invested by Chinese and Japanese party in 1998, specializes in developing, managing, manufacturing additives for new type of rubber with different performance such as anti-aging, acceleration, sulfuration. Meanwhile, we provide refined raw materials for more than 40 rubber enterprises in domestic and overseas as well as service of technology, prescription and craftwork arrangement. Since 2003 Self-Preparation Professional Production Line was established to produce motorcycle inside and outside tube. Many kinds of indexes have passed through the most rigorous international certificate from Germany, America and Japan, such as outer tube anti-wear, rolling resistance, driving performance, airtightness of inner tube, elongation rate, heat fatigue, long time of cracking resistance, anti-aging and tear strength since we combine our strong capacity of technology and prescription design. In addition we took use of self-developed rubber modification technology, concord and coupling technology of anti-aging, sulfuration and reinforcement.
