We make Polyvinylidene Fluoride (PVDF), a tough engineering thermoplastic that offers a unique balance of performance properties. Polyvinylidene Fluoride (PVDF), a thermopolymer of 1,1-difluoroethylene, is a tough engineering thermoplastic. PVDF Pipes have the characteristic properties of high resistance to chemical attacks intrinsic to all fluoropolymers based on the very high strength of the carbon – Fluorine atom bond
