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.
