Description

Kynar® resins are fluorinated thermoplastic homopolymers.

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

Kynar® UHM 6020-20 resin is a specific grade of granules for injection, extrusion, compression and transfer molding.

This grade has specific improved mechanical properties where extreme conditions in temperature and pressure are needed.
