PTFE is one of the best corrosion-resistant materials in the world today, so it is called the "Plastic King". It can be used in any kind of chemical medium for a long time, and its production has solved many problems in my country's chemical, petroleum, pharmaceutical and other fields. Polytetrafluoroethylene seals, gaskets, gaskets. Polytetrafluoroethylene seals, gaskets, and gaskets are made of suspension polymerized polytetrafluoroethylene resin. Compared with other plastics, PTFE has the characteristics of excellent chemical resistance and temperature resistance. It has been widely used as a sealing material and filling material. It has a high degree of chemical stability and excellent chemical resistance, such as strong acid, strong alkali, strong oxidant, etc., has outstanding heat resistance, cold resistance and abrasion resistance. The long-term use temperature range is -200-+250℃, and Excellent electrical insulation, and is not affected by temperature and frequency. In addition, it has the characteristics of non-sticking, non-absorbent, non-burning, etc. Suspended resin is generally molded and processed by molding and sintering. The resulting rods, plates or other profiles can be further processed by machining methods such as turning, drilling, and milling. The bar can be made into oriented film by turning and drawing, and made into Teflon tape with glass fiber.
