Txhaj tshuaj TPU-High hardness TPU / Khau pob luj taws TPU / Hnav-resistant virgin TPU

Thermoplastic polyurethane elastomer (TPU) yog ib hom elastomer uas tuaj yeem ua kom yas los ntawm kev cua sov thiab yaj los ntawm cov kuab tshuaj. Nws muaj cov khoom zoo heev xws li lub zog siab, kev tawv siab, kev hnav tsis kam thiab kev tiv thaiv roj. Nws muaj kev ua haujlwm zoo thiab siv dav hauv kev tiv thaiv lub tebchaws, kev kho mob, Khoom noj thiab lwm yam lag luam. Thermoplastic Polyurethane muaj ob hom: polyester hom thiab polyether hom, dawb random spherical lossis columnar particles, thiab qhov ceev yog 1.10 ~ 1.25g / cm3. Qhov ceev ntawm polyether hom yog me dua li ntawm polyester hom. Qhov kub hloov iav ntawm polyether hom yog 100.6 ~ 106.1 ℃, thiab qhov kub hloov iav ntawm polyester hom yog 108.9 ~ 122.8 ℃. Qhov kub brittleness ntawm polyether hom thiab polyester hom qis dua -62 ℃, thiab qhov kub tsis kam ntawm polyether hom zoo dua li ntawm polyester hom. Cov yam ntxwv zoo tshaj plaws ntawm polyurethane thermoplastic elastomers yog kev tiv taus zoo heev, tiv taus ozone zoo heev, tawv heev, muaj zog heev, elasticity zoo, tiv taus kub tsawg, tiv taus roj zoo, tiv taus tshuaj lom neeg thiab tiv taus ib puag ncig. Qhov ruaj khov hydrolytic ntawm hom ester siab dua li ntawm hom polyester.
