Properties of the modified /filled PTFE composites
(If not durable PTFE general these materials can be used instead try)
PTFE has excellent heat resistance, chemical resistance, non-adhesive and weather resistance, but due to the linear expansion coefficient of PTFE, poor dimensional stability, low hardness, abrasion resistance is poor, in large Under load showed a greater "cold", limited its application, in order to overcome these disadvantages, and according to different requirements, can be modified by adding appropriate amount of filler. (Filler, glass fiber, para-poly, molybdenum disulfide, polyester, graphite, carbon, carbon fiber, bronze powder, silica fume, etc.) in order to maintain its low friction at the same time, access to excellent wear resistance, high temperature of 350 degrees, high strength, high stiffness and dimensional stability.
