Description

Kynar Flex® resins are fluorinated thermoplastic copolymers.

Kynar Flex® 2950-05 resin is a pelletized, semi-crystalline VF2 based copolymer. It has been designed for wire and cable applications requiring high flexibility and improved resistance to impact.The low molecular weight allows extrusion conditions that reduce jacket shrink back over fiber optic constructions.

Additional characteristics:

Excellent thermal stability

Excellent abrasion resistance

Excellent chemical resistance

Impervious to UV degradation

High Limiting Oxygen Index

Extremely low smoke emission characteristics

Meets UL910 requirements
