Polyethersulfone (PES)
Description (definition)
Polyethersulfone (PES) is an amorphous, transparent high-performance plastic known for its excellent heat and chemical resistance. PES is characterized by high dimensional stability, low moisture absorption and good electrical insulating properties. The plastic remains dimensionally stable at temperatures of up to 200 °C, making it ideal for applications in medical technology, the electrical industry and food processing.
An example
A typical example of PES is its use in reusable medical devices such as dialysis filters or surgical instrument housings that require regular sterilization. Its heat resistance and transparency ensure long-lasting function and hygienic handling.
What advantages does PES offer in medical technology?
PES is biocompatible, sterilizable and chemically resistant, which is why it is often used in surgical instruments, dialysis components and sterile containers. Its durability and transparency facilitate visual inspection and ensure hygienic standards.
Where is PES used in the electrical industry?
In the electrical industry, PES is used in insulating materials, connectors and housings for high-performance components. Its excellent electrical insulating properties and temperature resistance make it ideal for demanding applications.
Is PES recyclable?
PES is recyclable, but the recycling process requires special procedures to maintain the high material properties. Recycled PES is often used in less critical applications, such as technical housings or components.
