Description

Kynar Flex® resins are fluorinated thermoplastic copolymers.

Kynar Ultraflex® resin is a semi-crystalline copolymer of vinylidene fluoride and hexafluoropropylene. This copolymer is a highly flexible material that can be melt processed using typical melt processing equipment or can be easily put in solution for solution coating process. It can be supplied in as pellets for melt processing or as crumb to facilitate dissolution. This is the most flexible Kynar Flex® resin grade available.
