低模量聚醚型PU弹性体力学性能的研究

Study of mechanical property of moduser polyther polyurethane elastomer

研究了由聚醚二醇 (PPG、PTMG)、80 / 2 0 -TDI和扩链剂制备的PU弹性体 ,并讨论了聚醚软段 ,聚醚分子量 ,弹性体交联点分子量和硬段浓度对弹性体力学性能的影响。

Polyurethane elastomer of low modulus have been prepared by polyether,tolyene diisocyanate and bends of di and tri glycol.The mechanical properties of polyurethane are studied utilizing tensile testing.
