GEHR Plastics PVDF-ELS Polyvinylidene Fluoride, Electrically Conductive
Categories:	Polymer; Thermoplastic; Fluoropolymer; Polyvinylidene Fluoride (PVDF)
Material Notes:	Polyvinylidene fluoride shows a higher tensile strength, pressure resistance and dimensional stability than the related PTFE, but friction and insulation properties are lower. PVDF has a high mechanical strength and toughness at lower temperature and it's self-extinguishing. The temperature ranges from -30°C to 150°C. Properties high tensile strength high mechanical strength high rigidity high chemical resistance very low water absorption good friction and wear and tear values self-extinguishing high UV-resistance toxic fumes when burned can not be solvent cemented relatively high coefficient of thermal expansion Applications include gaskets, pumps, rotation disks, valves, flap traps, centrifugals of extraction, fittings, glide tracks, and cogwheels.
