PVDF
Non Melt
Melt
PVDF is a partially fluorinated polymer and is a homopolymer of vinylidene fluoride which has low to high melt viscosity with resistance to harsh thermal, chemical and ultraviolet environments. It is widely used for piping conveying halogenated compounds but should not be used in the service where the pH is above 11. It cannot tolerate esters, ketones or aldehydes. Available as pellets or as powder for rotational molding.
Working Temperature Range: -40deg. C to 150deg. C
