High acid and chemical resistance

Polyvinylidene-fluorides are semi-fluoride thermoplastics, in which the standard hydrogen atoms of carbon mainchain are partially (57%) replaced by fluorine atoms. PVDF-plastics combine excellent mechanical, thermal and electrical characteristics with outstanding chemical resistance. Based on their versatile possibilities of use in different temperature ranges, polyvinylide fluorides are often used in medical technology.
