Description

Kynar Flex® resins are fluorinated thermoplastic copolymers.

Kynar Flex® ADX 2250-05 resin is a semi-crystalline flexible functionalized copolymer designed for co-extrusion with other materials to improve interlayer adhesion. It is particularly suited to tubing, pipe and film co-extrusion applications.

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

More over, this grade increases the potential of adhesion on materials as polyamides, polyolefins and can be coextruded.
