| Kynar Flex® resins are fluorinated thermoplastic copolymers. Outstanding characteristics: chemical resistance, imperviousness to UV, high barrier properties, high purity, good mechanical and thermo-mechanical properties. Main applications: flexible tubing, corrosion protection in the chemical industry, coating (painting, co-extrusion), off shore, wire and cable jacketing with and without cross-linking. Kynar Flex® resin is a standard grade of granules, compared to the homopolymer grades, which exhibits a lower modulus, a better resistance to stress cracking in alkaline and oxidizing media, and a lower melting point. For cable coating, extrusion of tube and plaque, injection molding. Additional characteristics: Easily processed using conventional equipment Excellent thermal stability Retains properties after aging Pigmentable UL RTI temperature rating 125°C&& |
