Dawn Special Elastomer Company is a leading enterprise in the development, production, and sale of HNBR products. Based on cutting-edge technology and high added value, Dawn extends its rubber processing and production downstream. The hydrogenated nitrile rubber plant has a designed capacity of 3,000 tons per year, and the first phase of production of 1,000 tons was achieved in 2019.
So, what is HNBR rubber and why is it special?
HNBR, or hydrogenated nitrile rubber, is a highly saturated elastomer that is treated by special hydrogenation. It is similar to NBR, or nitrile rubber, but with a unique molecular structure that contains a small amount of or no carbon-carbon double bonds. This means that HNBR has better thermal oxygen aging (it can withstand a working temperature of 150℃ for a long time), ozone resistance, radiation resistance, and good dynamic properties. Additionally, HNBR has good resistance to chemically corrosive mediums, especially hydrogen sulfide.
Despite these unique features, HNBR maintains the oil resistance and wear resistance of NBR. This makes it an ideal material for use in harsh environments that require high temperature and chemical resistance, such as the automotive and oil industries.
In summary, Dawn HNBR rubber is a high-tech, high-value material with numerous applications and advantages. With Dawn Special Elastomer Company's expertise and commitment to quality, customers can be confident in the performance and durability of their products.
