polyethersulfone

Download Datasheet (pdf 39kb)

High resistance to heat and combustibility, low smoke emission, and transparency are the combination of properties possessed by stock shapes extruded from PES. These, coupled with light weight, good impact resistance, dimensional stability, and chemical resistance, make stock shapes extruded from PES resin useful in the electrical/electronics, aerospace/aircraft, automotive, and mass transit industries. PES stock shapes are also applicable for heat and fire safety, food service, and hospital and health care items.

The following physical property information is based on typical values of the base polyethersulfone resin (PES).

PES

Applications Include:
Printed circuits
High intensity light bases
Safety face shields
Machine guards
Connectors

Advantages of PES
Low smoke generation
Excellent electrical properties at elevated temperatures
Transparency
Excellent chemical resistance
Easily machined

Manufacturing Capabilities:
Rod: 3/16" to 6" diameter
Sheet: .035" to 4" thick
Film: .001" to .029" thick
Slab: 1/4" to 4" thick

Color/Grades:
Transparent (custom colors available)

*In addition to our standard capabilities, Westlake also has the ability to process custom resins in various sizes and colors with some exceptions.
