Nirmala pumps and equipments offer premium quality Polyvinylidene Fluoride (PVDF) is a tough engineering thermoplastic that offers a unique balance of performance properties. NPE Pump's Polyvinylidene fluoride (PVDF), the homopolymer of 1,1-difluoromethylene, is a tough engineering thermoplastic.
About PVDF Polymer
The unique structure of alternating methylene and difluoromethylene units along the chain creates a polymer material having high crystalline 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.
PVDF-based copolymers 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.
