Description

Kynar® polyvinylidene fluoride (PVDF), the homopolymer of 1,1-di-fluoro-ethene (VF2), is a tough, engineering thermoplastic that offers a unique balance of properties. It has high stability when exposed to harsh thermal, chemicals, and ultraviolet environments. Kynar® resins are readily melt-processed by standard methods of extrusion and injection / compression molding.

Kynar Flex® resins are a series of PVDF-based fluoropolymers with higher flexibility than conventional PVDF.

Properties

Kynar® PVDF’s properties include high mechanical strength and toughness, high abrasion resistance and high thermal stability. As a fluoropolymer, Kynar® PVDF boasts outstanding resistance to most chemicals and solvents, ultraviolets and weathering. Furthermore, Kynar® PVDF is used for its high purity and low permeability to most gases and liquids. Kynar® PVDF is also appreciated for its low flame and smoke characteristics.

Kynar Flex® resins are similar to Kynar® resins with respect to purity and chemical resistance, but possess unique qualities of additional chemical compatibility in high pH solutions, increased impact strength at ambient and colder temperatures and increased clarity.
