Modified reinforced graphite carbon black ptfe flat gasket

PTFE parts PolyTetraFluoroEthylene is a fluorocarbon-based polymer and is commonly abbreviated PTFE.The brand of PTFE is manufactured only by DuPont.it offers high chemical resistance, low and high temperature capability, resistance to weathering, low friction, electrical and thermal insulation.PTFE's mechanical properties are low compared to other plastics,but its mechanical properties can be enhanced by adding fillers such as glass fibers, carbon, graphite, molybdenum disulphide, and bronze.

PTFE graphite gasket is one of the many types of gaskets with a wide range of uses, its raw material is made of natural graphite after chemical treatment and high temperature treatment of 1,000 degrees Celsius from the expandable graphite or known as flexible graphite, natural graphite after treatment to become flexible graphite, with its excellent heat resistance and chemical resistance, this characteristic makes the gasket made of it in the very low temperature to 400 ℃ spanning a wide range of temperatures within the sealing performance is almost unchanged, and almost all of the special body shows excellent chemical resistance.

PTFE graphite gaskets have very superior performance, its thermal stability and excellent, changes in external temperature has little effect on its sealing, it also has a rare self-lubricating function, coupled with corrosion resistance, does not age, and does not become brittle, so that it is in harsh conditions to ensure long-term stability of the use of the general do not need to be maintained, due to its excellent characteristics, are widely used in a variety of piping, valves, pressure vessels, heat exchangers, condensers, generators, air compressors, exhaust pipes, refrigerators, and a variety of pumps and other equipment.
