The tetrafluoroethylene product is made of polytetrafluoroethylene resin, China Teflon Back-up Rod Seal Manufacturer which is sintered by cold pressing with a mold, and has excellent corrosion resistance, good self-lubricity and non-blocking property. Therefore, the product is almost resistant to all chemical media and has the characteristics of wear resistance, pressure resistance and low friction coefficient. It is widely used in petroleum, chemical metallurgical machinery, transportation, medicine, food, electricity and many other fields.

PTFE has excellent chemical stability, wide temperature range, good corrosion resistance and other excellent properties widely used in chemical, pharmaceutical, environmental protection, nuclear industry, daily necessities and other industries. However, the PTFE material is easy to be cold flow, has poor creep creep resistance, and has poor compression resilience, which seriously restricts its application in the sealing industry. Therefore, at present, filler modification, expansion modification and the like are often used to improve the polytetrafluoroethylene material. The PTFE sealing material prepared by this method fails to form a eutectic with other modified materials, and the filled modified material still exists in the form of its own particles, and the physical and mechanical properties of the prepared polytetrafluoroethylene composite material are obtained. Poor. The manufacturing process of the PTFE sealing product is a method of cold pressing forming, high temperature sintering, shaping and turning processing of the polytetrafluoroethylene material or its modified material. The PTFE sealing product prepared by this method has poor mechanical properties at high temperature, high temperature creep, large wear, poor resilience performance, poor product dimensional accuracy, long processing cycle and low production efficiency. Low utilization of materials.
