Fluorine rubber O-ring temperature Viton o-ring is a copolymer of vinyl fluoride and hexafluoropropylene, the proportion of up to 1.85. Depending on the molecular structure and the amount of fluoride, fluorine rubber chemical resistance and low temperature resistance also different. Viton advantage is that from the fire self-extinguishing, excellent air tightness, ozone resistance, weather resistance, aging resistance, the use of an organic peroxide vulcanizing Viton products made of a more excellent performance. Can provide DuPont Viton series elastomer seals are. Including generic brands A-type (fluorine content 66%), B-type (fluorine content 67-68.5%), F-type GF-type (fluorine content 70%), GLT GFLT (low temperature rating), Viton ETP (better chemical resistance), Viton TFE / P (preferably acid properties). Static sealing temperature range: -26-232 degrees short time up to 275 degrees dynamic seal: -15-200 degrees GLT type: -45-215 degrees Hardness SHORE A 50-90 Black is also the color used by the customer to specify the scope of application of fluorine When the seal is made of rubber for automobile sealing aircraft engines, long-term use at 250 degrees, for engine power output shaft seal can also be used for engine valve stem seals, cylinder liner seals, clutch seals, air filtration sealed and fuel pump seals. Viton seals can be used only under a high vacuum environment, at 1.33 * 10-7pa under other types of rubber can not be sealed. Therefore FKM has wide application in the aerospace field. Fluoro rubber seal can be used for inorganic acid medium, nitric acid in sulfuric acid at 140 degrees 90 degrees or less concentrated hydrochloric acid in long-term use, it can be specially formulated for aqua regia. The semiconductor industry, can be used for 275 degrees below medium silicon tetrachloride gallium arsenide phosphorus oxychloride and the like. Viton GLT has a wider temperature range, and excellent resistance to corrosion performance HTS mineral oil, commonly used in the aerospace field. Viton ETP broader chemical resistance Kunshan Hui Yang sealing products - have strong technical force and production capacity, the rubber O-ring is suitable for installation in various machinery and equipment, at a predetermined temperature, pressure, and various liquid and gaseous media, in stationary or moving began to seal. In the bathroom, shipbuilding, automotive, hardware, electronics, toys, electronics, aerospace equipment, machinery, and a variety of instruments, large-scale application of various types of sealing elements. Rubber O-ring is mainly used for static seals and reciprocating seals. Seal for rotary motion, the only low-speed rotary sealing device. Rubber O-ring is usually installed in the outer or inner circle cross-section from the seal rectangular groove. Rubber O-ring in the oil, acid, wear, chemical erosion and other environmental still play a good sealing, cushioning effect. Therefore, the rubber O-rings are used in hydraulic and pneumatic drive system most widely used seal. Kunshan Hui Yang Sealing Products Co., Ltd.
