PVDF is a kind of engineering plastic withsuperior comprehensive performance, not only having excellent mechanicalproperties, but also superior resistance to corrosion, high temperature,ultraviolet, radiation, and abrasion. The working temperature ranges from -70 ℃to 150 ℃. Moreover, it enjoys good toughness, with the tensile stretch at breakup to 300 percent and abrasion resistance similar to nylon.
