  • What is Polyethersulfone (PES) Filter?
    Filtration is undoubtedly an integral part of most industrial applications. From protecting equipment to separating contaminants from a solution, it is undoubtedly the lifeblood of every industry and most applications.
     
    Today, more than ever, filtration applications are more demanding in terms of volume and intensity. One of the leading filter choices in this regard is Polyethersulfone.
     
    PES filters are fast becoming the leading choice. Thus, you’ve probably heard of it and wondering what the hype is all about. So, in this guide, we will cover all you need to know about PES filters.
     
    Let’s dive in.
     
    Basics of Polyethersulfone Filter
    Polyethersulfone is perhaps the most popular and functional material for commercial filter fabrication. Polyethersulfone is a high-performance polyethersulfone material belonging to the sulfone family. This is a family of thermoplastic resins, known for their transparency, high-temperature resistance, and stability over a range of temperatures.
     
    These microporous filters are tailored to be acid-free and resistant. So, you can use it to filter a vast range of particulates. Also, PES materials are known for their high-quality assurance. Thus, you can use them for applications related to food and others with strict standards.
     
    This material can be used to create durable micro-porous film asymmetric filters. These filters are great when it comes to removing various particulates from solutions during general industrial filtration processes.
     
    Besides, polyethersulfone filters also exhibit superior drug-binding features. These are necessary when you have to recover important drugs during I.V therapy. Besides, they also come in handy for recovery during open heart surgeries and chemotherapy.
     
    One of the most recent developments in making thin film composite filters with PES is using the sulfonated form of polyethersulfone as the substrate. The sulfonated PES OR SPES means adding sulfonic acid orthogonally to the aryl group of the polyethersulfone. When you sulfonated the polymers, it does great to meet up with the performance of unmodified PES.
     
    Polyethersulfone filters are also hydrophilic and low-binding materials. These features make them the suitable choice for tissue culture media sterilization, microbiology and life science fluid application, and other general filtration procedures.
     
    PES filters also promise a considerable level of quality standards for every step in your production process. It allows you to create products with uniform pores. With this, you can be sure of reasonable particle retention, purification values, and flow rates.
     
    Further, these filters have innate porosity and controllable pore sizes, which is also necessary for drug recovery as mentioned before.
     
    How we can help
    With our PES filters, you can be sure of superior durability and strength. This makes it the best option for aggressive handling. It is also great for use whenever you’re using automated equipment.
     
    So we can cater to the vast needs of our customers, our membrane technology is available in several pre-cut sheets, discs, and rolls.
     
    In fact, you have the choice to pick from various pore sizes. You can choose something tight or large enough to offer you just the right capillary flow rate you need.
  • Polyethersulfone(PES) Structure
    Polyethersulfone is a pale amber, transparent, and amorphous thermoplastic resin. Amongst thermoplastic resin, it also doubles as the most temperature-resistant option that’s commercially available.
     
    The resin material, PES, also has commendable water reabsorption and maintains stability in several chemicals. With a pretty considerable glass transition temperature, it guarantees superior dimensional integrity over a vast temperature range.
     
    All these terrific properties are kudos to the chemical makeup and structure of the material. But before delving into its chemical structure, let’s take a quick look at its chemical preparation.
     
    Chemical preparation of polyethersulfone
    The industrial preparation of polyethersulfone is carried out by polycondensing relevant monomers to form a unit or polymerizing cyclic ether sulfone.
     
    One of the most popular approaches to achieving this is the nucleophilic substitution of fluorosulfone or cholrosulfone using phenoxide ions.
     
    Take, for instance, you could react a disodium bisphenol salt alongside dichlorodiophenyl. The output of this reaction will give polyethersulfone and sodium chloride.
     
    Chemical Structure of PES
    Chemically, polyethersulfone is called Poly(oxy-1,4-phenylenesulfonyl-1,4-phenylene)]. This is a material manufactured via the synthesis of polyester or polysulfonation.
     
    The chemical structure of the material features multiple aromatic rings. These aromatic rings could either be that of biphenyl or phenol groups. These rings are then linked alternatively using sulfone and other groups, as shown below.
    5
    The structure of polyethersulfone is somewhat similar to that of polyetherketone. However, in the sulfonic group, in this case, acts as a substitute for the right-hand O-phenyl-CO section of polyetherketone.
     
    The bond linkage between the structures is those with high thermal stability. This is what ensures that the material does not deform in any way over a wide range of temperatures. This could even be as high as 200°C, which is more than enough for most applications. An instance is in medical equipment. These materials are often subject to high temperatures for sterilization. Thus, when you use polyethersulfone, you can be sure that the dimensions are still stable regardless of the temperature to which you subject the material to.
     
    The bond is also responsible for its considerable oxidative stability. This is what makes the material suitable for use with several chemicals. However, considering its structure, it might not perform so well when it comes to other aromatic chemicals.
     
    The sulfone group attached to the material also reinforces its superiorly high-temperature performance. The ether linkage, on the other hand, helps with practical processing. In essence, it ensures that the polymer chains are very mobile when they are in the melt phase.
     
    In Closing
    Polyethersulfone has a somewhat straightforward structure, simply comprising linked phenyl and sulfone units. Both units add several distinct benefits to their build-ups and applications. For instance, we said the sulfone group is responsible for the high operational temperature stability it boasts. This chemical build-up is also responsible for its suitability for applications across automotive, electrical, industrial, and membrane applications.
     
    So, if you’re still wondering whether or not is the material for you, well, you have to stop now. It is definitely for you. Now, reach out to us and we will gladly lead you on the right path to get you started.
  • Polyethersulfone(PES) vs Polysulfone
    Perhaps, the biggest difference between polyethersulfone and polysulfone is that polysulfone is made up of repeating sulfone units. On the other hand, polyethersulfone has the aryl-SO2-aryl makeup.
     
    There are essentially three materials belonging to the polysulfone family. These include:
     Polyethersulfone
    Polysulfone
    Polyphenylene
     
    While these materials are generally high-performing and suitable for high-temperature usages, there are still some basic differences between them.
     
    So, in this guide, we will pit polyethersulfone against polysulfone and see which one fits your bill the best.
     
    Let’s dive in.
     
    Polysulfone-the basics
    Polysulfone is a member of the higher-performing thermoplastic polysulfone family. These are polymers renowned for their toughness and ability to maintain dimension stability, even at considerable temperatures.
     
    Polysulfone, PSU, is the product formed when the fulsome functional group of bis(4-chlorophenyl)sulfone reacts with the chloride functional group of diphenoxide in a substitution reaction.
     
    The materials formed from polysulfone show some inherent properties such as high rigidity, strength, and stability. They also show superior stiffness. However, they can only maintain these properties between the range of 100°C and 150 °C.
     
    Further, polysulfone has a glass transition temperature that ranges between 190°C to 230 °C. This is to confirm that the dimensional stability of the material is quite satisfactory for several applications. It will only change in size when you expose it to a temperature that is above 150°C.
     
    Just like most materials belonging to the polysulfone family, PSU also shows superior resistance to electrolytes, alkalis, and mineral acids as long as their pH value neither exceeds nor falls below two to 13. Its chemical makeup also makes it insusceptible to an oxidizing agent. So, you have no worries if you’re using bleach.
     
    Polyethersulfone – the basics
    Here is another high-performing thermoplastic material. Its usage is most common in applications such as wastewater treatment and membrane bioreactor material.
     
    In a nutshell, polyethersulfone chemical structure comprises sulfone and other bonds linked to phenyl.
     
    Compared to polysulfone, this material does better when it comes to temperature resistance. In essence, it does well under a temperature as high as 400°C.
     
    Polyethersulfone is a pale amber, amorphous and transparent thermoplastic material. In the polysulfone family, it has the highest temperature resistance and commercial availability. On top of that, it has minimal water absorption and hardly creeps.
     
    What are the differences between polyethersulfone and polysulfone?
    There are truckloads of differentiating factors between polysulfone and polyethersulfone. For one, polyethersulfone can show dimensional stability under a temperature as high as 400° C. However polysulfone cannot even go up to half this temperature. Its ability is limited to roughly 150°C, as mentioned before. For this reason, polysulfone may not be as good as PES for high-temperature applications such as in medical equipment where objects are subject to high heat for sterilization. On top of that, polyethersulfone also does superiorly when it comes to glass transition temperatures.
     
    Another difference is in their structure and chemical makeup. While polyethersulfone contains the ether group, this group is comparatively absent in the polysulfone family. Thus, it is relatively limited when it comes to certain applications.
  • Polyethersulfone (PES) Chemical Compatibility
    When it comes to chemical resistance, some chemicals can hurt your polyethersulfone while some will not. Now, the issue is identifying these chemicals. With this understanding, you can easily avoid them and prolong the lifespan of your PES material.
     
    So, in this article, we will range through a quick guide on which chemicals are compatible with your PES material and those that are not. 
     
    The chemical compatibility, as discussed in this guide, will take a look at how PES reacts with various chemicals when subjected to the chemicals for under 48 hours at about 25 degrees Celsius. 
     
    These recommendations were birthed from extensive testing by TPP. However, note that these were under actual working conditions.
     
    PES is undoubtedly one of the most integral polymers and is applicable in a vast range of niches. Especially, membranes have found great prevalence across biomedical niches. Also, the modified forms, such as sulfonated polyethersulfone further reinforce the hydrophilic property of the material for superior filtration processes. 
     
    Now, let’s take a looks at the compatibility of the material with various chemicals. 
     
    How compatible is PES with various chemicals? 
    We will discuss this section under three headings. The first is the chemicals, to which PES is highly resistant. The second is those where it has limited resistance. And the third are the ones that completely damage the polymer. 
     
    Chemicals that PES is highly resistant to.
    The first set is certain acids such as: 
     Nitric acid 
    Hydrofluoric acid 
    Chromic acid 
    ​​​​​​​ Hydrochloric acid 
    ​​​​​​​ Acetic acid 
    ​​​​​​​ Sulfuric acid. 
     
    Some alcohols are also very compatible. Some of these include methanol, ethanol, butanol, isopropanol, and amyl alcohol. 
     
    PES is also highly compatible with certain oils. These include sesame oil, cottonseed oil, peanut oil, and several others. 
     
    In addition, the high compatibility of PES further spans halogenated hydrocarbons such as freon. Plus, you can use the PES with esters such as amyl acetate, dioxane, ethyl acetate, tetrahydrofuran, etc.
     
    Chemicals where PES has limited resistance 
    These chemicals include certain alcohols such as benzyl alcohol. It is also worth noting that the PES material shows limited resistance to every form of aromatic hydrocarbon. These include xylene, benzene, toluene, etc. Halogenated hydrocarbons such as carbon tetrachloride also show limited resistance. 
     
    The ones that completely damage the polymer
    Some of the chemicals that can damage your PES are ketones. Almost every form of ketone will damage the material. These include: 
     Methyl ethyl ketone 
    ​​​​​​​ Methyl isobutyl ketone 
    ​​​​​​​ Acetone 
    ​​​​​​​ Cyclohexanone 
     
    Any of these materials are not compatible with your PES. As such, they might completely damage it. 
     
    Also, you want to completely avoid contact with certain halogenated hydrocarbons such as: 
    ​​​​​​​ Chloroform 
    ​​​​​​​ Methyl chloride 
    ​​​​​​​ Dowclene

  • Polyethersulfone (PES) Membrane Properties
    Polyethersulfone (PES) membrane is undoubtedly a popular choice for several general filtration procedures. For one, it is the most suitable choice for removing fine particles from solutions. These particles include fungi, bacteria, etc.
     
    For this reason, the PES membrane is a versatile pick for processes like sterile filtration, preparation of certain samples, and I.V therapy. 
     
    Naturally, PES is hydrophilic. For this reason, it attracts water and gets wet easily. Thus, it tends to filter things faster than other materials available. On top of this, it further guarantees an elevated flow rate and superior throughputs. 
     
    The membranes are also inherently low-protein binding. For this reason, it minimizes the tendency of target analyte binding for certain procedures. Whether you’re striking with an autoclave or gamma radiation, the material is also sure to retain its functionality and dimensional stability effortlessly. 
     
    Now, we've seen a high-level overview of the properties that set PES membranes apart. Now, the next step is properly defining them. To do this, we will take a look at some of those areas where these properties are best felt. 
     
    With no further ado, let's delve right into it. 
     
    Properties for medical processes 
    This is where the hydrophilic nature of polyethersulfone gets to flex its muscles. One such is infusion therapy. With the polyethersulfone membrane, you can be sure of a relatively quicker finished device priming. Since it gets wet relatively quicker, it also guarantees higher throughput for a longer period. The membrane also features a uniform pore structure. This property is best felt when it comes to sterile fluid and particulate retention. 
     
    Properties that are relevant in the preparation of samples. 
    The PES membrane is characterized by minimal protein binding characteristics. This feature is what makes it great for preparing a vast range of biological samples. You can also get PES membranes in several pore sizes, making it a versatile choice. The membrane slots in effortlessly for removing coarse particulate in applications related to pre-filtration. It also does well to help you remove fine particulate for final sample clarification. 
     
    That’s not all. PES doubles as the leading pick for multiplexed and bead-based assays. It further helps bring the tendency of false positives to the barest minimum in serological assays. 
     
    Properties applicable to microbial analysis 
    You can find the polyethersulfone membrane in the modified black form. In this format, the membrane offers you just the right contrast you need for particulate and microbiological analyses. With the dark background, you can get good contrasts. This makes it easier to estimate opaque colonies in your laboratory. It also makes it easier to monitor lightly stained particulates in the fluids being observed. If you’re looking to isolate and count your yeast and mold colonies, the PES membrane can help you do that effortlessly. 
     
    Properties that make it suitable for sterile filtration 
    PES membrane is available in several pore sizes. You can get sizes from 0.1 to 0.2 micrometers. This is suitable for buffer and culture sterilization as well as pharmaceutical filtration procedures. If you are worried about contamination from mycoplasma, the 0.1-micrometer pore size can rid you of this concern. 
  • Sulfonated Polyethersulfone(PES)
    As the name implies, sulfonated polyethersulfone, SPES, is obtained via a sulfonation reaction, occurring at room temperature in the presence of a mild sulfonating agent. 
     
    In the process of polyethersulfone sulfonation, chlorosulfonic acid acts as the sulfonating agent. There is also the need for a solvent in the reaction. This is where concentrated sulfuric acid comes into play. 
     
    FTIR confirms the presence of the sulfonic acid group in the sulfonated polyethersulfone. According to a study by thermogravimetric, membranes made from sulfonated polyethersulfone, also show superior thermal stability. This is to say that the membranes can guarantee dimensional stability over a vast range of temperatures. 
     
    By using N-methyl-2-pyrrolidone to test the SPES material, it was discovered that the tensile strength of the SPES membrane decreases as you increase the intensity of sulfonation. On the other hand, as the degree of the sulfonation increases, the affinity to water or water intake increases. 
     
    Comparing the sulfonated to unsulfonated polyethersulfone membrane, the sulfonated polyethersulfone reigns supreme when it comes to hydrophilicity. This implies that the material's interaction with water is better, and as such, it tends to filter things faster than most of the other materials. This hydrophilic nature was confirmed by a minimal angle of contact when tested with water. The atomic force microscopy phase images also confirm that the sulfonated membranes feature more considerable hydrophilicity at a higher degree of sulfonation. 
     
    The SPES membranes are also characterized by amorphous nature. This nature was discovered using the X-ray diffraction technique. 
     
    If you’re more than convinced that the sulfonated form of polyethersulfone is for you, be sure to reach out to us. We will help you identify your particular needs and draft out a plan, quote, and guide to help you bring everything to creative fruition. 
  • Modified Polyethersulfone (PES)
    Polyethersulfone is a material that has gained traction in several applications. To mention a few, these include waste treatment and a range of medical-related applications. This is largely due to their terrific thermal and mechanical properties. 
     
    However, one of the primary setbacks to the material is its hydrophobic degree. Sometimes, you can notice biofouling effects on the membrane. This strongly limits the potential of polyethersulfone in filtration membranes.
     
    To solve this problem, there is a rising need for modified polyethersulfone. One of the most popular approaches to creating modified polyethersulfone is surface motivation. With modification, you can easily ramp up the hydrophilicity of your material, thus speeding up the flow rate and the rate at which the filtration occurs. The modification also rids you of the concerns related to membrane fouling.
     
    Generally, modification means you’re introducing a hydrophilic functional group into the PES polymer. So, you will still retain the superior thermal and mechanical properties associated with polyethersulfone. On top of that, modified PES does well to elevate your permeate flux. 
     
    Speaking of permeate flux, it is important to note that the essence of designing a membrane is to create something that does well to reject absolute and permit the solvent. This is what modification tends to elevate. 
     
    In addition, there are various ways to introduce these hydrophilic functional groups. You can do this by copolymerizing the hydrophilic monomer with the monomer of polyethersulfone. This will help create a new hydrophilic polymer material. The second way is to simply introduce the hydrophilic functional group to the surface of the PES polymers. 
     
    The hydrophilic functional groups usually used are hydroxyl, carboxyl, and sulfone. Sulfone is the most popular and sulfonated polyethersulfones are some you should be looking forward to. 
  • Glass Transition Temperatures of (PES)
    Glass temperature is the temperature at which your polyethersulfone is transformed from ductile to glass. It is the temperature that changes your carbon chains. 
     
    Put simply, it is the temperature where the PES material has higher molecular mobility. This is usually a result of considerable temperature change. The glass transition temperature of polyethersulfone is 180 to 250 degrees Celcius. 
     
    When the temperature increases beyond this value, there will be considerable alterations in the resin’s thermal properties and dimensional stability. 
     
    In essence, above 250 degrees Celsius, the polyethersulfone polymer is subject to hysteresis and isotropic expansion. When it cools down, there will be dimensional changes, which can make the material ductile and rubbery. 
     
    Glass transition temperature directly correlates with the strengths and capabilities of the material. This ultimately translates into its particular end use. Glass transition temperatures also relate to the mechanical properties of PES. These include: 
     
     The temperature range at which it can operate 
    Module of elasticity 
    Tensile strength 
    Resistance to impact. 
     
    Considering all the glass transition temperatures, you can use the material for several purposes. One such is in medical components. As you know, medical components are subject to high standards when it comes to cleanliness. They must be sterilized to ensure they are kept uncontaminated, So, they need to be made of materials that can withstand high-temperature sterilisation processes. This is where PES comes to play. 
     
    Also, your engines tend to get so hot when in operation. Thus, you need a material that can withstand this temperature demand. Fortunately, the glass transition temperature of polyethersulfone makes this possible. 
     
    If the glass transition temperature of PES is more than enough to convince you that the material is for you, be sure to reach out to us and let's get you started.
