New Application Areas

摘要

Since early 1960 Vinylidne fluoride (VF2) based fluoropolymers are a class of polymers has been used in many types of chemical industry applications throughout the world. Often the acronym PVDF is used to describe a whole class of resins of which more than 100 separate commercial grades are known to exist. Each resin has specific application and while in most of the cases these resins can be used interchangeably for fluid handling applications. There are few cases in where selection of wrong grade has resulted in performance deficiency or even in system failure. It has been more than 20 years since an original paper was given to describe commercial availability of PVDF and modified PVDF resins to the pure water industry (9), since that time the number of modified PVDF grades has tripled. The intention of this paper is to introduce PVDF and PVDF Copolymer, discuss their properties/traditional application areas and new application areas like Li-ion Battery, membrane, films, foams & rotomolding articles.
