Product Description
PTFE skived sheet is manufactured by high-temperature sintering of premium PTFE resin, followed by precision skiving and polishing processes. It exhibits excellent high and low temperature resistance, allowing long-term operation within the temperature range of -185ºC to 260ºC. Besides, PTFE skived sheets have superior corrosion resistance, which can resist the erosion of almost all strong acids, strong alkalis, oxidants and other harmful chemical substances. In addition, they have an extremely low friction coefficient, one of the lowest among solid materials, making them widely used in mechanical sealing, bearing pads, and other industrial applications.
