TPU polyeter ah oo u adkaysta xirashada iyo heerkulka sare leh oo loogu talagalay shaabadda saliidda

Elastomer-ka Polyurethane-ka ee Thermoplastic (TPU) waa nooc ka mid ah elastomer-ka oo lagu kululayn karo kuleyliyaha laguna milmi karo dareeraha. Waxay leedahay sifooyin dhammaystiran oo aad u fiican sida xoog sare, adkaysi sare, iska caabin xirasho iyo iska caabin saliid. Waxay leedahay waxqabad wanaagsan oo wax lagu farsameeyo waxaana si weyn loogu isticmaalaa difaaca qaranka, caafimaadka, cuntada iyo warshadaha kale. Polyurethane-ka Thermoplastic-ka ah wuxuu leeyahay awood uu ku shaqeeyo Polyurethane-ka Thermoplastic-ka ah.slaba 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 polyester-ka waa 100.6~106.1℃, heerkulka kala-guurka galaaska ee nooca polyester-kana waa 108.9~122.8℃. Heerkulka jajabnaanta ee nooca polyether-ka iyo nooca polyester-ka ayaa ka hooseeya -62℃, iska caabbinta heerkulka hooseeya ee nooca polyester-kana way ka fiican tahay tan nooca polyester-ka. Astaamaha cajiibka ah ee elastomer-ka thermoplastic-ka ee polyurethane waa iska caabbinta xirashada oo aad u fiican, iska caabbinta ozone-ka oo aad u fiican, adkaanta sare, xoogga sare, dabacsanaanta wanaagsan, iska caabbinta heerkulka oo hooseeya, iska caabbinta saliidda oo wanaagsan, iska caabbinta kiimikada iyo iska caabbinta deegaanka. Xasiloonida hydrolytic ee nooca ester-ka ayaa aad uga sarreysa tan nooca polyester-ka.
