Description

Kynar Flex® resins are fluorinated thermoplastic copolymers.

Outstanding characteristics: chemical resistance, imperviousness to UV, high barrier properties, high purity, good mechanical and thermo-mechanical properties.

Kynar Flex® 2800-00 resin is a standard grade of granules, compared to the homopolymer grades, which exhibits a lower modulus, a better resistance to stress cracking in alkaline and oxidizing media, and a lower melting point. For cable coating, extrusion of tube and plaque, compression molding of bulky parts.

Additional characteristics:

  • Easily processed using conventional equipment
  • Excellent thermal stability
  • Retains properties after aging
  • Pigmentable
  • UL RTI temperature rating 125ºC
  • Radiation crosslinking
