Data Sheets for Download:

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.

The following physical property information is based on typical values of the base Ultrason® E resin as well as test results obtained from actual film testing.

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
