| Kynar® resins are fluorinated thermoplastic homopolymers. Kynar® 370 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 with a higher HDT. This grade is especially modified in order to have a reduced mold shrinkage, low thermal expansion factor. Moreover, this grade has an increased thermal and electrical conductivity. This grade is available as pellet form for injection, extrusion, compression.&& |
