Message

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 trasit industries.

Applications Include:

Liquid crystal displays

Radomes

Magnet wire insulation

Hot melt adhesives

Flex circuitry

High temperature labels

Advantages of 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
