HNBR

HNBR

HNBR is a hydrogenated NBR rubber. NBR is a copolymer of ACN and 1,3-butadiene. The NBR backbone contains double bonds remaining from the 1,3-butadiene monomer units. These double bonds are also prone to chemical attack, thermal degradation and oxidation. To improve these properties, NBR can be hydrogenated in a catalytic hydrogenation process to form HNBR, which is widely known for its physical strength and retention of properties after long-term exposure to heat, oil and chemicals. HNBR is used in a wide range of applications, including automotive (coolant, AdBlue, oil, fuel systems), industrial applications, oil and gas industries, food and pharma, and medical applications.
