| 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. 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&& |
