Description

Kynar® resins are fluorinated thermoplastic homopolymers.

Kynar® 340 resin is a thermoplastic fluorinated polymer resin. The properties are the same as standard grade: chemical resistance, resistance to UV, low permeation, high purity, excellent mechanical behavior. More over, this grade is electrically conductive. This grade is available as pellet form for injection, extrusion, compression.
