PVDF is a tough, stable fluoropolymer with distinct engineering advantages.
A semi-crystalline thermoplastic, PVDF is used in applications requiring the highest of purity and will withstand harsh chemicals, PVDF is one of the highest radiation resistance plastics available, only seconded by PEEK and Polyimide.It's highly desirable insolubility and electrical properties results from the polarity of alternating CH2 and CH2 groups on the polymer chain
PVDF has a low density (1.78/cm3) compared to other fluoropolymers.PVDF is available in Rod, Tube and Sheet form and is processed by Injection moulding, compression moulding and hot moulding. Commonly used in the Semiconductor, defence, chemical and medical industries as well as in the production of lithium-ion batteries.
