Kynar Flex® resins are fluorinated thermoplastic copolymers.

Kynar Flex® 2850-02 has been specifically designed for use in wire and cable constructions which require an Underwriters Laboratories temperature of 150ºC and a Limiting Oxygen Index (LOI) of at least 75.

Kynar Flex® 2850-02 is easily processed and has excellent physical, mechanical, thermal and flame resistant characteristics.

Kynar Flex® 2850-02 meets the smoke and flame requirements of UL 910 and ASTM E84 (the Modified Steiner Tunnel Test). This copolymer is commonly used for pipe, wire jacketing, conduits, and in injection molded parts. ADDITIONAL CHARACTERISTICS:

  • Excellent thermal stability
  • Excellent abrasion resistance
  • Impervious to UV degradation
  • Self extinguishing material
  • Extremely low smoke emission characteristics
  • 0/0 rating in ASTM E-84/UL 723

  • This material data has been provided by Arkema High Performance Polymers.
