Txhaj TPU-High hardness TPU / khau luj taws TPU / Hnav-tiv taus nkauj xwb TPU

Thermoplastic polyurethane elastomer (TPU) yog ib hom elastomer uas tuaj yeem ua yas los ntawm cua sov thiab yaj los ntawm hnyav. Nws muaj cov khoom zoo heev xws li lub zog siab, siab toughness, hnav tsis kam thiab roj tsis kam. Nws muaj kev ua haujlwm zoo thiab siv dav hauv kev tiv thaiv hauv tebchaws, kev kho mob, Khoom noj khoom haus thiab lwm yam lag luam. Thermoplastic Polyurethane muaj ob hom: polyester hom thiab polyether hom, dawb random kheej kheej los yog columnar hais, thiab qhov ceev yog 1.10 ~ 1.25g / cm3. Cov txheeb ze ntom ntom ntawm polyether yog me dua li ntawm polyester hom. Cov iav hloov pauv kub ntawm polyether hom yog 100.6 ~ 106.1 ℃, thiab iav hloov kub ntawm polyester hom yog 108.9 ~ 122.8 ℃. Lub brittleness kub ntawm polyether hom thiab polyester hom yog qis dua -62 ℃, thiab qhov kub tsis kam ntawm polyether hom yog zoo dua li ntawm polyester hom. Cov yam ntxwv zoo ntawm polyurethane thermoplastic elastomers yog zoo heev hnav tsis kam, zoo heev ozone kuj, siab hardness, siab zog, zoo elasticity, tsis kub tsis kam, zoo roj kuj, tshuaj tsis kam thiab ib puag ncig kuj. Lub hydrolytic stability ntawm ester hom yog ntau dua li ntawm polyester hom.
