PVDF transparent film, PVDF solar cell front sheet film , PVDF solar cell film

PVDF (polyvinylidene fluoride) is a kind of light fluoride material, with the working temperature ranging from -70 to 150 . It features superior corrosion resistance, mechanical property, electrical insulating property, low friction coefficient, weatherability, and radiation tolerance. Moreover, the tensile strength is two times higher than PTFE, the compressive strength six times higher than PTFE, and the abrasion resistance similar to nylon.
