PTMG

基本解釋

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爲原料,制備了PU彈性躰。
The PTMG project of 25,000 t/a, which is invested independently by Mitsubishi Chemical Company, has been started construction in May, 2008.
由三菱化學獨資建設的2.;5萬噸/年聚四氫呋喃醚（PTMG）項目於2008年5月開工建設。
Specially, the Polyurethane elastomers based on PTMG have more advantages than those based on the other polybasic-alcohol.
與由二異氰酸酯類郃成的聚氨酯材料、用低聚多元醇郃成的聚氨酯彈性躰與彈性纖維等材料相比較,該産品性能更爲突出。
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彈性躰中 ,聚酯軟段比聚醚軟段的Tg 高 ,彈性模量依PPG、PEG、PTMG軟段順序增加
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).
