Rubber gasket

NBRsyntheticsilicone

Main features of NBR rubber gasket: Excellent oil resistance Nitrile rubber has excellent anti-permeability and stability to petroleum-based media such as mineral oil, lubricating oil, hydraulic oil, diesel, gasoline, etc. It is an ideal sealing material for hydraulic systems, engines, fuel tanks and other environments. Good wear and tear resistance The molecular structure of NBR gives it high mechanical strength, and it is not easy to be worn quickly even on contact surfaces with friction or slight movement. Strong sealing and small compression deformation It has good compression rebound performance and can provide stable and reliable sealing in flanges, threaded connections, pumps and valves. Wide applicable temperature range The general operating temperature range is -25℃ to +100℃, and the special formula can be extended to -40℃ ~ +120℃, which is suitable for most normal temperature to medium temperature conditions. Good water resistance, alcohol resistance, silicone oil resistance and other properties In addition to petroleum-based liquids, it also has certain resistance to certain polar liquids such as water, ethanol, and silicone oil (but not ketones, esters and strong polar solvents). Obvious processing and cost advantages NBR gaskets can be mass-produced by molding, stamping, laser cutting, etc., with mature technology and high cost performance. It is the preferred material for most medium and low pressure seals. Typical application scenarios: Petrochemical equipment seals (such as oil pumps, fuel pipe joints, oil tank flanges) Automobile engine and gearbox seals
