PVDF (Polyvinyl idene Fluoride) PIPE

PVDF (Polyvinyl idene Fluoride) PIPE


Polyvinyl idene Fluoride (PVDF) is a tough engineering thermoplastic that offers a unique balance of performance properties. 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 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.

Resins area series of PVDF-based copolymers similar to 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. Suitable for the delivery of pharmaceutical grade purified water (PW) and DI water, using hot water, steam chemical or ozone sa nitisation. Dueto its excellent chemical resistance it is widely used in chemical distribution systems.

PVDF pipes, fittings and mountings from ASVA Piping Systems are sold under the ASVA brand.
