| Kynar Flex® resins are fluorinated thermoplastic copolymers. Outstanding characteristics: chemical resistance, imperviousness to UV, high barrier properties,high purity, good mechanical and thermomechanical properties. Main applications: injection molded and co-extrusion applications requiring the high chemical and temperature resistance properties of Kynar 2850-00 resin. Kynar Flex® 2850-04 resin is a standard grade of granules less flexible than the grade Kynar Flex® 2800-20 resin with a higher melting point. It has a UL RTI temperature rating of 140 degrees C.&& |
