So much for the o-ring, and you still don't know what it's made of? The o-ring is one of the more commonly used sealing rings at present. Because of the different working conditions used, the requirements for the sealing rings are mostly different, so there are many types of sealing rings, so what are the Common Materials of o-rings? Under what circumstances does it apply? Common seal ring materials are hydrogenated butanediol rubber, butanediol rubber, silicone rubber, fluorine rubber, fluorine silicone rubber, butyl rubber, etc. . 1. hydrogenated butadiene-cyanogen rubber, with good corrosion resistance, compression resistance and tear resistance, but also to resist ozone, sunlight and oil damage, it is suitable for o-ring in automotive engine, washing machine and new type ring refrigeration system, but it can not be used in Ester, alcohol and aromatic solvent. 2. BUTYL cyanogen rubber, low cost, widely used, generally used in water, silicone oil, glycol hydraulic oil and other media, but in ozone, ketone nitrohydrocarbon polar solution is not suitable for use. 3. Silicone rubber, which is cold resistant, heat resistant, and resistant to ozone and atmospheric aging, but has poor tensile properties and is not oil resistant, is commonly used in o-rings for household appliances, for example, microwave oven, water heater, electric iron, drinking machine, kettle, etc. . 4, fluorine element rubber, has the good ozone resistance and the weather resistance, the high temperature resistance performance is also better than the silicon rubber, but the cold resistance is poor. Generally used in fuel systems and chemical plants o seal ring, in the Ketone, nitrate mixture is not recommended. 5、 fluorine silicon rubber, fluorine silicon rubber combined the advantage of silicon rubber and fluorine rubber, can resist the erosion of oxygenated compound, fluorine containing solvent and aromatic hydrocarbon containing solvent, the performance of oil resistance, fuel oil resistance and solvent resistance is good. Generally used in the military and aerospace field o-seal, in the brake oil and ketones are not recommended. 6. butyl rubber are heat resistant and air tight, resistant to sunlight, polar solvents and ozone, well insulated, and can be exposed to oxides or animal or vegetable oils, o-rings are generally used in vacuum equipment and chemical resistant products and should not be used with petroleum, aromatics or kerosene. In addition, o-ring materials also neoprene, acrylate rubber, natural rubber, perfluoro rubber, EPDM rubber and polytetrafluoroethylene, according to the specific needs of customers, support customized! Choose a suitable sealing ring, not only to reduce the cost of use, but also long product life, safety performance is also high! Suggest to buy sealing ring, consult experienced manufacturers, can give reasonable advice, one-to-one service, ensure quality, but also to provide perfect after-sales service.
