Berry Rubber Auxiliary Co., Ltd., The company is engaged in research, producing as well as sell. We are the member of China Rubber Industry Association. Our corporation already through ISO9001: 2000 quality management system authentication in 2002. We are professional in producing rubberantioxidants, 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, calledDBHA 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. Theproduction scale of DOTG, refined M, refined DM, refined TETD and Si69 (HP669) is be expanded. We also have new non-pollution compound auxiliaries like 4010NA(N), 4020(N), Rubber AntioxidantA, 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 antilight aging performance; Improved the phenomenon that agglomeratedand hard to weighing and use in summer. Beijing Rubber Industry Research and Designing Instituteof China Chemical Industrial Department have carried out the test on the new products, and the testresult shows that the new products have better performances than the old ones. The new product alsowon recognition in practice.
