PVDF
High purity engineering plastic with excellent chemical, abrasion, and flame resistance
PVDF (polyvinylidene fluoride), often referred to by its trade name Kynar®, is a high purity engineering thermoplastic with excellent chemical resistance, abrasion resistance, flame resistance, and UV stability. PVDF is widely used for chemical tank liners and semiconductor equipment components. FDA compliant grades of PVDF are available.

PVDF Properties and Material Options
Homopolymer PVDF– has higher strength and stiffness and has a higher heat deflection temperature than copolymer PVDF.
Copolymer PVDF– is less stiff but has superior impact and stress crack resistance.
