Duritaanka TPU- Adkayn sare TPU/ Kabo cidhibta TPU/ TPU bikrad ah oo u adkaysta xirashada

Elastomer-ka Polyurethane-ka ee Thermoplastic (TPU) waa nooc ka mid ah elastomer-ka kaas oo lagu kululayn karo laguna milmi karo dareeraha. Waxay leedahay sifooyin dhammaystiran oo heer sare ah sida xoog sare, adkaysi sare, iska caabinta xirashada iyo iska caabinta saliidda. Waxay leedahay waxqabad wanaagsan oo wax lagu farsameeyo waxaana si weyn loogu isticmaalaa difaaca qaranka, caafimaadka, cuntada iyo warshadaha kale. Polyurethane-ka Thermoplastic wuxuu leeyahay laba nooc: nooca polyester-ka iyo nooca polyether-ka, walxaha cad ee wareegsan ama tiirarka ah ee aan kala sooca lahayn, cufnaantuna waa 1.10 ~ 1.25g/cm3. Cufnaanta qaraabada ah ee nooca polyether-ka ayaa ka yar tan nooca polyester-ka. Heerkulka kala-guurka galaaska ee nooca polyether-ka waa 100.6 ~ 106.1℃, heerkulka kala-guurka galaaska ee nooca polyester-ka waa 108.9 ~ 122.8℃. Heerkulka jajabnaanta ee nooca polyether-ka iyo nooca polyester-ka ayaa ka hooseeya -62℃, iska caabinta heerkulka hooseeya ee nooca polyether-ka ayaa ka wanaagsan kan nooca polyester-ka. Astaamaha ugu fiican ee polyurethane thermoplastic elastomers waa iska caabin aad u fiican oo xirasho ah, iska caabin ozone oo aad u fiican, adkeysi sare, xoog sare, dabacsanaan wanaagsan, iska caabin heerkul hooseeya, iska caabin saliid oo wanaagsan, iska caabin kiimiko iyo iska caabin deegaan. Xasiloonida hydrolytic ee nooca ester-ka ayaa aad uga sarreysa tan nooca polyester-ka.
