Materyel TPU: polymerized elastome termoplastik. Pou reyaksyon an polymerization nan TPU ak monome ki gen rapo, TPU se yon reyaksyon jwenti nan difenylmethane diisocyanate (MDI) oswa pou diminye toluene (TDI) ak lot molekil diisocyanate ak pisin makromolekile ak ba-molekile pisin (chen pwolonje) Polymerized materyel polymere. Estrikti molekile li se yon blok rijid jwenn pa reyaksyon an nan difenylmethane diisocyanate (MDI) oswa diisocyanate toluene (TDI) ak yon pwolonje chen, ak diisocyanate tankou difenylmethane diocyanate (MDI) oswa diisocyanate toluene (TDI) segman yo chen fleksib jwenn nan reyaksyon an nan molekil ak pisin makromolekile yo variantes fome.
