摘要
通过对低聚物多元醇和扩链剂的选择,研制出邵D硬度大于75、缺口冲击强度大于6kJ/m2的高硬度聚氨酯弹性体,生产工艺完全适合工业化生产技术要求。
Through the choice of low polymer and chain extender, this paper develops a high hardness polyurethane elastomer, the hardness of which is more than Shore D 75, the gap impact intention of which is more than 6 kg/m^2, and the production technique of which totally fits in with the technical requirements of the industrialized production.
