Oil Resistance And Low Temperature Resistance HNBR Compound Rubber For Seals
Description:
HNBR is made via selective hydrogenation of the NBR butadiene groups which improves the temperature and ozone resistance considerably. HNBR is widely known for its physical strength and retention of properties after long-term exposure to heat, oil, and chemicals. HNBR has better heat resistance; oxidation resistance; tensile strength and abrasion resistance than standard nitrile (NBR). Also an excellent choice for automotiverefrigerant service.Hydrogenated nirtrile results from the hydrogenation of standard nitrile.
Temperature range:-25℉to 300℉
Application:
Oil industry Auto car industry Aircraft industry
Compound rubber products and hydrogenated nitrile rubber plate, molding products.

After-sales tip
HNBR material used in very widely applications, please confirmed typical properties and chemical resistance before ask for the sample. Our bulk production formula will be same with the sample. Once anything difference with the arrangement we support third part test, if its our fault we have duty to help customer solve the problem or agree return the products.
