Zhejiang Huangyan Zhedong Rubber Auxiliary Co.,Ltd. is combined with Jintan Zhedong Rubber Auxiliary Factory, Wuxue Zhedong Rubber Auxiliary Factory, Hebi Zhedong Rubber Auxiliary Factory and Huangyan Zhedong Rubber Auxiliary Imp. & Exp. Co., Ltd.. The company is engaged in research, producing as well as sell. We are the member of China Rubber Industry Association. Our annual output value is 300 million Yuan. Our corporation already through ISO9001:2000 quality management system authentication in 2002. We are professional in producing rubber antioxidants, accelerators and anti aging agents. Now we have more than 50 kinds of rubber auxiliaries in order to satisfy our customer. "Rely on the quality and credit standing for the survival and the development" is our management philosophy. Depend on our superior technics, we exploited HTDM that has excellent effect when it used as vulcanization accelerator instead of DTDM. We are the only one who can make it in China and it conforms to the international requirement. And we also exploited 2 anti aging agents, called DBHA and LD. According to the market, we changed our producing technic to increase the contents of 2, 3, 4 polymer in RD up to more than 60%; improved sieve residue to more than 300um. The production scale of DOTG, refined M, refined DM, refined TETD and Si-69 (HP-669) is be expanded. We also have new non-pollution compound auxiliaries like MB(N), 4010NA(N), 4020(N), Rubber Antioxidant A, Rubber Antioxidant etc.. Especially 4010A(N) and 4020(N) have the follow merits: lower water extracting rate; lower toxicity ;improved dispersivity and coordination; enhanced the anti-light aging performance; improved the phenomenon that agglomerated and hard to weighing and use in summer. Beijing Rubber Industry Research and Designing Institute of China Chemical Industrial Department have carried out the test on the new products, and the test result shows that the new products have better performances than the old ones.
