It has excellent resistance to acids, weak bases, hydrocarbons and halogenated compounds, but strong bases, caustics, esters and ketones can cause degradation. PVDF resists ultraviolet (UV) and gamma radiation. It has good mechanical strength, toughness and abrasion resistance, with thermal stability from -40 °C to 150 °C. The material is water-resistant and has flame-retardant properties.. || Please see the technical image illustration for size references.
