| 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: piping systems, corrosion protection in the chemical industry and lined pipe, off shore, wire and cable. Kynar Flex® 2850-00 resin is a standard grade of granules less flexible than the grade Kynar Flex® 2800-00 resin with a higher melting point. For extrusion, wire and cable constructions which require an UL wire ratings to 150 degrees C. Also for applications requiring a UL RTI temperature rating of 140 degrees C. A powder form is available as Kynar Flex® 2851-00 resin.&& |
