Hydrogenated nitrile rubber compound-HNBR
Product Description
This material is based on hydrogenated nitrile rubber (HNBR). It is specially designed for the production of rubber products. It is widely used in some rubber products factories abroad. It has high strength, high hardness, heat resistance, oil resistance and H2S resistance. It is resistant to acid and alkali, low compression and permanent deformation, and has good process performance.
