Hydrogenated nitrile rubber hydraulic O-ring is more excellent performance

Hydrogenated nitrile rubber (HNBR) is nitrile rubber in the unsaturated double bond by catalytic hydrogenation made. Hydrogenated nitrile rubber of hydraulic O-ring As the main chain tends to saturation, so in addition to maintaining its excellent oil resistance, rubber elasticity, heat resistance, acid resistance, aging resistance and physical properties are greatly improved. Such as the use of temperature can be as high as 170-180 ?, cold-resistant temperature of -50 to -380 ?. The presence of a small amount of C = C bond allows the hydrogenated nitrile rubber to be sulfur cured. Nitrile rubber is a non-crystalline rubber, but hydrogenated into a tensile crystalline rubber. Hydrogenated nitrile rubber hydraulic O-ring has excellent heat resistance, oxidation resistance and oil resistance, in many ways to replace the fluorine rubber or other special rubber, is widely used in automotive, oilfield mining, aerospace and other industrial fields, as times New Materials of Concern. Hydrogenated nitrile rubber research has made significant progress, successfully developed a new Jan catalyst and its catalytic degradation and hydrogenation, such as technology and processing technology, by optimizing the catalytic hydrogenation conditions for the preparation of hydrogenated nitrile rubber excellent performance.

TFE / P, NBR can not withstand high temperature acidic medium environment, and HNBR show the best performance. The static and dynamic ozone resistance test results of the HNBR samples showed no ozone cracking after 1000 hours and showed excellent ozone aging resistance.

Hydrogenated nitrile rubber hydraulic O-ring processing performance is better than FKM, similar to ordinary NBR, you can fill more filler. The use of sulfur vulcanized HNBR compounds has a much higher adhesive performance than peroxide vulcanization because the sulfur in the compound is chemically reactive with the fiber or metal material.

Hydrogenated nitrile rubber hydraulic O-ring commonly used in high temperature, fuel and other harsh environments, requiring the use of plasticizers must be difficult to volatile, resistant to extraction.

Hydrogenated nitrile rubber hydraulic O-ring has good chemical resistance and heat resistance, suitable for the production of various industrial rubber, oil resistance and abrasion resistance is particularly outstanding ZSC is even more compelling, ZSC even Hardness of more than 90 degrees, the processing viscosity is also very low, easy to shape, than the strength of polyurethane rubber, water resistance, oil resistance have a large improvement, suitable for high hardness rubber.
