What are the types of rubber sealing products

Rubber seals are made of one or several parts of the ring-shaped cover, fixed in the bearing of a ring or gasket and another set of rings or gasket contact or the formation of narrow labyrinth gap, to prevent lubricating oil leakage and the intrusion of foreign objects.　Rubber seals (O-ring, Y-ring) of the common types 1, O-type rubber seals O-type rubber seals O-type rubber seals are owned by fluorine rubber, nitrile rubber, silicone and other materials, O-type rubber seals are widely used in a variety of machinery, resistant to various types of petroleum-based oils and a variety of chemical media: O-type rubber seals using different rubber to meet the -60 ℃ - +300 ℃ temperature range, O-type rubber sealing rings. The use of pressure range: <10MPa (hydraulic), <1MPa (pneumatic) <16MPa (static sealing) of the butyl rubber and gasoline-resistant with (90, 93, 97) expansion rate of 0. 2, Y-type rubber seals Y-type rubber seals are fluorine rubber, butyl rubber, chlorine rubber and other materials used to produce a variety of products, Y-type rubber seals are widely used in the hydraulic, mechanical, Pneumatic and other industries. Resistant to petroleum-based oil has excellent abrasion resistance, Y-type rubber seals with different rubber raw materials to meet the -60 ℃ - +300 ℃ temperature region.　3, silicone rubber sealing ring series Silicone rubber sealing ring products are widely used in electronics, medical equipment, food and other industries.　Silicone rubber sealing ring raw materials are generally domestic, imported silicone, the use of temperature can meet -60 ° - +300 ° C, silicone rubber sealing ring to meet the oil resistance, steam resistance, medical, food equipment use.　　 4、Fluoroelastomer sealing ring series Fluoroelastomer sealing ring series of products, widely used in automotive, shipbuilding, military, electronics and electrical industries, the working temperature of fluoroelastomer sealing ring in -40 ° C +300 ° C, can be resistant to fuel oil, high temperature, Freon, resistance to hot water, steam and excellent chemical resistance.　5、Polytetrafluoroethylene rubber sealing ring (gasket) series Polytetrafluoroethylene rubber sealing ring (gasket) has high temperature resistance, corrosion resistance, even at high temperatures and concentrated acids, alkalis or strong oxidizing agents do not react, polytetrafluoroethylene rubber sealing ring (gasket) has been widely used as a sealing material, polytetrafluoroethylene rubber sealing ring (gasket) for pipelines, flanges, reaction kettles, valves and containers on the sealing The rubber sealing ring is generally made of butyl chloride (Buna-N).　Rubber seals are generally made of nitrile rubber, natural rubber, nitrile rubber is made of butadiene and acrylonitrile by emulsion polymerization, nitrile rubber is mainly produced by low-temperature emulsion polymerization, with excellent oil resistance, high abrasion resistance, good heat resistance and strong adhesion; natural rubber is a kind of natural macromolecular compounds with polyisoprene as the main ingredient, and the molecular formula is (C5H8)n, and 91%~94% of its composition is rubber. 91% to 94% is rubber hydrocarbon (polyisoprene), the rest is protein, fatty acids, ash, sugar and other non-rubber substances. Natural rubber is the most widely used general-purpose rubber.　Scope of application of rubber seals: mainly for hydraulic and pneumatic systems and a variety of mechanical equipment and components, in the specified pressure, temperature and different liquid and gas media, at rest or in motion to play a sealing role. Rubber seals suitable for the working temperature of -40 ~ +230 ℃
