PVDFKYNAR FLEX

PVDFKYNAR FLEX

We stocks Kynar Flex™ 2750 (PVDF) tubing. The material has several properties which make it ideal for a broad range of demanding applications. Kynar Flex™ 2750 is FDA compliant and meets USP Class VI requirements. Also, it has low TOC, excellent chemical resistance to most strong chemicals, is UV stable, and is rated for high temperatures. Kynar Flex™ 2750 is widely accepted in a range of industries and is known as an excellent and economical alternative to Teflon™ and other fluoropolymers. In many cases it has superior mechanical properties over more expensive fluoropolymers in its class.
