Guangzhou SF Sealing Technology Co., Ltd. is specialized in producing single lip, lips, three PTFE lip seal manufacturers. Quality PTFE lip and stainless steel frame, is a powerful guarantee of high quality oil seal. Products are mainly used for high-precision, high-friction, high pressure, high temperature and strong corrosion and some rubber seal incompetence environment, is one of high quality oil seals seal products. PTFE seal lip portion of the company is chosen filled modified PTFE (mainly filled with glass fiber, carbon fiber, graphite, molybdenum disulfide), to improve the wear resistance of PTFE, stainless steel skeleton. Meanwhile, in the product structure of our company imitation of similar products imported from Europe to deal with, to ensure that products with the former bit of reality. At the same price, guaranteed cheap. My company's PTFE seal has the following advantages: First, with excellent chemical stability, resistant to almost all chemicals can be used in water, strong acids, strong bases, strong oxidizing capacity of agents, such as methane gas seals on. Two, has excellent anti-friction properties, PTFE lip friction coefficient is relatively low, only 0.02, is one of 40 points of rubber, and especially suitable for oil-less oil in the working state, even when the machine is again used for a long also can have low friction immediately. Third, able to withstand greater pressure 2MPa, rubber seal only 0.03MPa, especially for high-speed rotating applications at speeds up to 30M / S can work within a temperature range of -100 ℃ -250 ℃. Four, PTFE lip pulled in the processing of a horn-like, due to memory after PTFE has been drawn contractility, frictional heat generated in the work to make lip shrinking, so do not need the help of the spring, will be tightly in the shaft, do not let a gap exists with the shaft surface, but also to compensate for wear. Five Shelf: lips seal / reverse screw 7,42 * 38 * 52 * 62 * 8, 45 * 62 * 8, 45 * 65 * 8, 48 * 62 * 8, 48 * 65 * 10,48 * 70 * 10,49 * 72 * 10, 54 * 73 * 10,55 * 72 * 80 * 8,60 * 8,55 * 8,60 * 80 * 80 * 85 * 10.65 * 10.65 * 85 * 8 65 * 90 * 10, 68 * 90 * 12, 70 * 10,68 * 100 * 100 * 100 * 12 * 10,75 At present, our company's PTFE seals are mainly used in air compressors, vacuum pumps, compressors, engines , motors, air conditioners, blenders, automatic precision machinery, robotics, chemical processing equipment, pharmaceutical and food processing equipment, etc., especially for rubber seal can not be competent environment.
