Polyethersulfone (PES Film) Specifications

Description

PES film possesses a combination of properties such as high resistance to heat and combustibility, low smoke emission and transparency. These coupled with light weight, high tear initiation and propagation strength, dimensional stability, chemical resistance and thermoformability make the film particularly useful in electrical, aerospace, automotive, and mass transit industries.

Applications

Liquid crystal displays • Radomes • Magnet wire insulation • Hot melt adhesives • Flex circuitry • High temperature labels

Advantages of Polyethersulfone (PES Film)

High heat deflection and continuous use temperature • Exceptional tensile and flexural strength • High dielectric strength • Exceptional mechanical properties • Dimensionally stable at varying temperatures • Transparency • Hydrolytically stable

Manufacturing Capabilities

Thicknesses and Widths: .001” to .010” up to 27” wide & .011” to .029” up to 26” wide • Finishes: all thicknesses available polished one side, matte the other (P/M)
