What is Polyethersulfone(PES) Used For?

The high-performance thermoplastic, PES, is finding its way into several applications today. This is due to its overwhelming range of superior properties. To mention a few, this includes its minimal flame resistance, high glass transition temperature, great optical clarity, etc.

In this article, we will take a quick look at some of those areas where you can use Polyethersulfone.

Let’s dive in.

Applications in the industrial settings

As mentioned before, the application of PES is pronounced in areas where other thermoplastics such as Polyamide prove ineffective. Also, it slots right into these industrial applications because of its high mechanical strength and operating temperatures.

Most commonly, you’ll find PES being used in valves and pumps for electrochemical and chemical applications. In essence, you can use it for components such as oil level indicators, conveyor belt filters, distillation columns, and several others.

Automotive applications

Polyethersulfone is now used for several automotive applications. Reinforcing the thermoplastic resin with carbon fiber or glass, you can use it to manufacture tons of automotive components. In fact, it has replaced thermostats and metals for most of these applications.

The material is revered for its superior temperature resistance. Thus, it is gradually replacing several engineering plastics for operations that exceed their capabilities.

Some of the most common places you'll find polyethersulfone in automotive is in components such as transmission parts, battery caps, oil control pistons, ignition parts, bearing cages, etc.

Further, you’ll also find PES in the headlight of your cars. It is usually used to make the housing, screen, and reflectors of the headlight.

Especially when you reinforce the material with glass, it slots perfectly into your engine oil circulation framework. This polymer blend elevates its dimensional and thermal stability. So, even when it comes in contact with hot oil, there won't be any noticeable effect.

Electrical applications of PES

PES is known for its great dimensional stability, as mentioned before. On top of this, it boasts great strength and stiffness. Thus, it is the perfect fit for several electronic and electrical applications.

Some of the places, where PES is applied in electronics, include injection molded boards, coils, relays, projector components, and battery seals.

Besides, this application further spans TV components, heat shields, battery seals, and even components of your fan heater.

Medical applications of polyethersulfone

PES can work excellently even when you subject it to high sterilization stress. This makes it one of the leading choices for making components of sterilization boxes, section bottles, syringes, and even dialyzer membranes. Further, the material also does well to resist the detrimental impacts of disinfectants and germicides. These reinforce its suitability for the range of medical components mentioned before.

For polyethersulfone membranes

Finally, PES is one of the most popular polymer materials when it comes to making commercial membranes. It can help you create durable film aesthetic membranes that can effectively help you separate particulates from solutions when going through general filtration.

PES membranes also show superior drug binding and low protein properties. This makes it work excellently to recover critical drugs. These drugs fit perfectly for open heart surgery and I.V therapy.
