Since 2006, Focus on rubber seals

Hydrogenated nitrile rubber seals have what performance?

by:ORK      2020-07-11
Along with the development of the automobile, petroleum industry, rubber seals in addition to the required oil resistant, also need to have good heat resistance, resistance to high temperature and high pressure, oxygen resistance and other properties, ordinary NBR NBR has far cannot meet these requirements, although some performance purpose has been replaced by fluorine rubber, the fluorine rubber bad low temperature resistance. So people began to explore the improvement on the properties of NBR hydrogenated nitrile rubber seals seal glue arises at the historic moment. Hydrogenated nitrile butadiene rubber ( HNBR) Is butadiene copolymer and propylene sunny, is a kind of special rubber, it is through all or part of the double bond of hydrogenated nitrile butadiene rubber. Its characteristics are mainly: 1, hydrogenated nitrile rubber seal 2, aging resistance, high mechanical strength and wear resistance and excellent ozone resistance ability 3, compression deformation resistance superior 4, hydrogenated nitrile rubber seals seal heat resistance is higher than nitrile rubber neoprene and about 30 ℃, temperature range of use: about 45 ℃ ~ + 150 ℃, short-term use can be 180 ℃ high temperature resistant, the disadvantage is that the price is higher. Above is hydrogenated nitrile rubber seal has some characteristics, because the price is high, so there is currently no nitrile rubber seals so wide application scope, but for some requirements higher product is more suitable. Sealing pieces 17 years of professional manufacturers, professional custom fit for the customer the rubber seals, such as more material problems, consulting, we welcome.
Most people who see a in operation for the first time are amazed at how well the custom rubber seals is managed.
