PTMG is a linear polyether glycol with primary hydroxyl groups at both ends. It easily reacts with isocyanates compounds (e.g. MDI, TDI), and generates polymers with the superior characteristic described below. ■ High impact resilience ■ Hydrolysis resistance ■ Flexibility at low temperature ■ Abrasion resistance ■ Tear resistance ■ Fungus resistance The PTMG
