Teflon Sealing element Alternative summary

Not in what circumstances can be replaced, asbestos, graphite, rubber, nylon and so on can replace Teflon seal. If you need corrosion resistance, temperature resistance and comprehensive performance of the material is PTFE, FEP is, but not so high temperature ptfe. Perfluoroethylene FEP (F46) and the material of polytetrafluoroethylene (F4) is similar, the fluorine plastics, high and low temperature resistance, self lubrication, resistance to chemical corrosion. FEP can also be injection molding production, easy recovery, comprehensive performance has been Wu less, but the price is much higher than that of polytetrafluoroethylene (F4). If you think the PTFE performance is not enough, can be considered in PTFE, PTFE can be filled with carbon fiber, copper powder, reinforced polyphenyl ester, improve his performance and life.
