NBR (nitrile rubber) sealsUsed in the petroleum series hydraulic oil, glycol Department of hydraulic oil, gasoline, water, silicone grease, silicone and other media. Is the most widely used, the lowest-cost rubber sealing material. Does not apply to polar solvents such as ketones, smelly itchy, nitro hydrocarbons, MEK and chloroform. Normal temperature range of - (yu3 lv4 fang3 _zheng4 chang2 shi3 yong4 wen1 du4 fan4 wei2 wei4 _) 40 °C ~ 120 °C.HNBR (hydrogenated nitrile rubber) ringHas good resistance to corrosion, tear-resistant and anti-compression deformation features such as resistance to stink itch, resistance to sunlight, oil resistance, good. Better abrasion resistance than nitrile rubber. For washing machines, car engine system and a new ring cooling system. Not suitable for use in alcohols, esters and aromatic solvents. The normal operating temperature range -40 ° C to 150 ° C.SIL (silicon rubber (_gui xiang) adhesive) ringHas excellent heat resistance, cold resistance, smelly itch, anti-air aging properties. There are good insulating property. Poor tensile strength than ordinary rubber, and non-oil resistance. Apply to household electric water heaters, electric irons, microwave ovens and other household electrical appliances, also applies to a variety of indirect contact with human skin supplies, such as kettles, water dispensers. Is not recommended for use in the most concentrated solvents, oils, concentrated acid and hydrogen itch sodium. The normal operating temperature range -55 ° C to 250 ° C.VITON (fluorine rubber) sealsTemperature resistance than silicone rubber has excellent weather resistance, resistance to the smelly itchy and chemical resistance, but poor resistance to cold. For the majority of oil, solvent resistance, especially acid class, aliphatic hydrocarbons and animal and vegetable oils. Can be used to seal the demand of diesel engines, fuel systems and chemical plants. Not suitable for use in ketones, low molecular weight esters and a mixture containing nitrate. The normal operating temperature range -20 °C to 220 °C.The FLS (fluorosilicone rubber) sealsThe performance of both the fluorine rubber and silicon (ta1 de0 xing4 neng2 jian1 you3 fu2 su4 xiang4 jiao1 ji2 gui1) the advantages of rubber, oil resistance, solvent resistance, fuel oil and resistant to high and low temperature are good. Can resist the itch containing the compounds, including the erosion of the aromatic hydrocarbon solvents and chlorinated solvents. Can be used in the aerospace and military applications. Not suitable for exposure to ketones and brake fluid. The general use of the temperature range -50 °C to 200 °C.EPDM (ethylene propylene diene monomer rubber) sealsGood weather resistance, smelly itchy, water resistance and chemical resistance. Alcohols and ketones, can also be used for the seal of high temperature water vapor environment. For in the bathroom, car radiators and car braking systems. Not suitable for food use or being exposed to mineral oil. General use temperature range is -55 °C ~ 150 °C.CR (chloroprene rubber) sealsResistance to sunlight, resistant to weather and excellent performance. Available in dichlorodifluoromethane and ammonia refrigerant, resistant to dilute acid, resistance to grease the Department of lubricants, but in the expansion of large amount of mineral oil with low aniline point. Easy to crystallize at low temperature hardening. Applicable to all kinds of contact with the atmosphere, the sun, smelly itchy environment and a variety of fire and chemical resistant seals links. Not suitable for use in the chemicals into the acid, nitro hydrocarbons, esters, chloroform, and ketones. General use temperature range is -55 °C ~ 120 °C.IIR (butyl rubber) sealsExcellent air tightness, heat resistance, sunlight resistance, smelly itchy, good insulation properties; polar solvents such as alcohols, ketones, esters, such as resistance, can be exposed to animal and vegetable oils or itching compounds. Can be applied to the chemical resistance or vacuum equipment. Not suitable for use with petroleum solvents, kerosene or aromatics. The general use of the temperature range -50 °C to 110 °C.ACM (acrylic fat rubber) sealsOils have excellent the (jue mian you lei you you xiu de) resistance, high temperature, weather good, but the compression deformation rate and water resistance, mechanical strength, somewhat less. Generally used for vehicle transmission and power steering system into. Is not recommended for hot water, brake fluid into the phosphate. The general temperature range from -25 ° C to 170 ° C.Nr (natural rubber) sealsHas good abrasion resistance, flexibility, tensile strength and elongation. But easy to aging in the air, when heated, becomes sticky, and easy expansion and dissolved in mineral oil or gasoline, alkali but impatience strong acid that can be used in the automotive car oil, ethanol solution containing ions of hydrogen itch normal Operating temperature range -20 °C to 100 °C.Pu (polyurethane rubber) sealsExcellent mechanical properties of polyurethane rubber, wear resistance, high voltage performance are superior to other rubber. Aging resistance, resistance to the smelly itchy, oil resistance, or when the temperature is easily hydrolyzed. Applicable to high pressure resistance, wear sealed link, such as hydraulic cylinders. General use temperature range is -45 °C ~ 90 °C.FFKM (perfluorinated rubber) sealsExcellent resistance to chemical corrosion, acid, alkali, ketones, esters, ethers, strong itch agent and the vast majority of known chemicals. The highest heat to 300 °C. Usually used to solve complex sealing problems of the environment, nearly a hundred times higher price than ordinary rubber material is very expensive, of course, good sealing effect, and can be used in a very strict environment, irreplaceable.PTFE (polytetrafluoroethylene) sealsPTFE PTFE (ju4 si4 fu2 yi3 xi1 zai4) industry, aviation, electrical, chemical, mechanical, instrumentation, metal surface treatment, medicine, food, metallurgy smelting, hydraulic and other widely used as high temperature resistance, corrosion-resistant materials low coefficient of friction, insulation material, anti-sticking coating, it has become an irreplaceable product.
