Polyvinlidene Fluoride PVDF Pipe and fittings

PVDF Pipe fittings

PVDF Pipe fittings are made up of Polyvinlidene Fluoride PVDF.  it is a tough engineering thermoplastic that offers a unique balance of performance properties. Polyvinylidene fluoride PVDF, the homo polymer of 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 crystalline combined with a high polarity resulting in a sharp melting point. Thus PVDF has the characteristic stability of fluoropolymers when exposed to harsh thermal, chemical and ultraviolet environments while retaining the properties of a conventional thermoplastic material.

Resins area series of PVDF-based co-polymers similar to homo-polymer 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 sanitation. Due to its excellent chemical resistance it is widely used in chemical distribution system

Polyvinlidene Fluoride (PVDF) is a unique thermoplastic with properties which allow it to be used for very aggressive or highly specialized applications. Although expensive compared to other thermoplastics, PVDF offers an economically attractive alternative to many “exotic” materials and/or in process lines where limited working life of other materials necessitates frequent replacement.

PVDF has excellent chemical and physical properties, even at low temperatures, and has considerable resistance to abrasion. It is resistant to most of the inorganic acids and bases, and to aliphatic and aromatic hydrocarbons, organic acids, alcohols and hydrogenated solvents. It is also non-toxic and can be used for high purity applications.

Safe working temperatures range from -40ºC to +120ºC, with short term use possible at temperatures well above this level.

PVDF pipe systems are assembled using heat fusion welding, either using socket fittings or butt fusion of pipes and/or fittings end to end.
