稀土异戊橡胶用于载重胎可40%替代天然橡胶

Rare-earth Isopentadiene Rubber Used on Heavy-load Tyre Substitute for 40% of Caoutchouc

近日，由中科院长春应用化学研究所和中国石油吉林石化分公司研究院共同承担的国家科技支撑计划项目“异戊橡胶生产技术开发”研发出新的稀土异戊橡胶。这种稀土异戊橡胶中试产品成功应用于全钢载重子午轮胎，可40％替代天然橡胶，经中国橡胶工业协会材料检测研究中心检测评价，轮胎的成型、加工和使用性能基本不受影响。

Products of new rare-earth Isopentadiene rubber have been successfully used on whole-steel heavy-load meridian tyres,which substituted for 40% of caoutchouc. Through testing and evaluation by the Research Center for Material Testing of China Rubber Industry Association,moulding of the tyres,machining and usage performance are basically not affected.
