国家反应注射成型工程技术研究中心技术人员分别用低不饱和度聚醚多元醇Ａｒｃｏｌ - 42 0 0、ＰＴＭＧ和聚酯制备聚氨酯弹性体 ,进行了力学性能比较。测试结果表明 ,在邵氏Ａ硬度为 80度时 ,用Ａｒｃｏｌ- 42 0 0聚醚制备的聚氨酯弹性体性能较ＰＴＭＧ和聚酯型聚氨酯弹性体优?
National reactive injection molding engineering and technical research center technicians respectively using low unsaturated polyether polyol Arcol - 42 0 0, PTMG and polyester prepared polyurethane elastomer, the mechanical properties were compared. The test results show that the polyurethane elastomer prepared with Arcol-420o polyether has better properties than PTMG and polyester polyurethane elastomer at a Shore A hardness of 80 degrees.
