Product Texts

Kynar Flex® resins are fluorinated thermoplastic copolymers.

Kynar Flex® 3121-50 is a pelletized flexible, semi-crystalline VF2 based copolymer. It can be molded or extruded and has a useful temperature range from -40°C - 150°C. Kynar Flex® 3120-50 has a UL RTI of 150°C. This product is NSF/ANSI/CAN 61 certified. 

Kynar Flex® 3120-50 can be used in compounding for cross-linkable wire and cable as well as both wire applications requiring low temperature flexibility and high temperature resistance.

Kynar Flex® 3120-50 also finds use as a polymer processing aid (PPA) for polyolefins. The use of Kynar Flex® 3120-50 or Kynar Flex 3121-50 at 200 -1000 ppm levels reduces extruder pressure, improves surface finish, reduces die build up, and improves gauge control.
