polyvinylidene fluoride


Manufactured from Kynar® polyvinylidene fluoride resin. This material offers excellent corrosion and chemical resistance at both ambient and elevated temperatures. PVDF is also inherently UV stable, mechanically tough, abrasion and flame resistant.

The following physical property information is based on typical values of the base resin polyvinylidene fluoride resin.

Kynar® 740

*In addition to our standard capabilities, Westlake also has the ability to process custom resins in various sizes and colors with some exceptions.

Kynar® is a Registered Trademark of Atofina, Inc.
