HNBR is a kind of highly saturated special elastomer obtained by hydrotreating NBR.Compared with NBR, the molecular structure of HNBR contains little or no carbon carbon double bond, while maintaining NBR oil resistance, abrasion resistance and other performance at the same time, also has more excellent heat-resistant oxygen aging (can be long-term work under 150 ℃), ozone resistance, radiation resistance, resistance to chemical media to hydrogen sulphide has good resistance to tolerance and good dynamic performance, etc., is a kind of comprehensive performance of special rubber.
Dawn HNBR competitive advantage
1.Adopt self-developed core catalyst.
2.At present, Dawn Special Elastomer Materials Co., Ltd. is the largest HNBR manufacturers in China, and Dawn Group has strong financial strength and brand influence.
3.Our ultimate goal is "stable product quality + domestic price".
