PTMG

基本解释

Polyurethane elastomers based on glycols(PEA,PPG PTMG), diisocyanate(TDI) and chain extender(E-300) were prepared.
以多元醇(PEA,PPG,PTMG),PDI,E 300为原料,制备了PU弹性体。
The PTMG project of 25,000 t/a, which is invested independently by Mitsubishi Chemical Company, has been started construction in May, 2008.
由三菱化学独资建设的2.;5万吨/年聚四氢呋喃醚（PTMG）项目于2008年5月开工建设。
Specially, the Polyurethane elastomers based on PTMG have more advantages than those based on the other polybasic-alcohol.
与由二异氰酸酯类合成的聚氨酯材料、用低聚多元醇合成的聚氨酯弹性体与弹性纤维等材料相比较,该产品性能更为突出。
The T g of polyester soft segment is higher than of polyether soft segment,and the elastic modulus increases in the order of PPG PEG PTMG in the PU elastomer.
在PU弹性体中 ,聚酯软段比聚醚软段的Tg 高 ,弹性模量依PPG、PEG、PTMG软段顺序增加
And two new segmented poly(urethaneureas) were prepared from poly(tetramethylene glycol)(PTMG) or polyadipate of 1,4 butanediol(PBA), MDI and Urea(as chain extender).
通过对聚氨酯脲及其硬段模型化合物的结构与性能的研究，发现这种体系有高相分离程度、高氢键密度的特点，并暗示了三维氢键网络结构的存在。
