KYNAR ® Polyvinylidene Fluoride (PVDF) is a tough engineering thermoplastic that offers a unique balance of performance properties. KYNAR ® polyvinylidene fluoride (PVDF), the homopolymer of 1,1-difluoroethylene, is a tough engineering thermoplastic. The unique structure of alternating methylene and difluoromethylene units along the chain create a polymer material having high crystallinity combined with a high polarity resulting in a sharp melting point. Thus KYNAR ® PVDF has the characteristic stability of fluoropoly-mers when exposed to harsh thermal, chemical and ultraviolet environments while retaining the properties of a conventional thermoplastic material.
KYNAR FLEX® resins are a series of PVDF-based copolymers similar to KYNAR® homopolymer resins in purity and chemical resistance, but having additional chemical compatibility in high pH solutions, increased impact strength at ambient and low temperatures, and increased clarity. |
