Profile: Jiangsu Changxin Airproof Material Co., Ltd. specializes in manufacturing PTFE, teflon and other engineering plastic products. We are an ISO 9001:2000 certified company. Our products include PTFE rods, tubes, sheets, films and FPM products. Our extruded tubes and rods are made from PTFE resin with appropriate additive through the process of extruding & sintering. Our PTFE film is made from PTFE rough, with the process of skiving, pressing, trimming and cutting. They are highly crystalline and have high intensity & excellence in anti-voltage & mechanical properties. Our molded and skived sheets are free from bubble, layer, mechanical damage & external impurities with smooth surface. These are compatible with QB/T3625-1999 standard. We also offer FPM sealing parts including framework oil seals, seal rings, gaskets and ropes. The FPM is a synthetic polymeric elastomer. It is an excellent elastic engineering material, widely used in various industries such as aviation, automobile, shipbuilding, mechanics, chemical and light industry. The mechanical sealing capability of FPM exceeds PTFE products, and its anti-corrosion ability is better than other rubber products. Our products are widely applied in compressors, photo-electronic, power circuit breaker, valves, instruments, pneumatic components, boilers, and construction machinery.
