TPU/Thermoplastic Polyurethane Tpu granules/compounds don Waya da Kebul

Elastomer na Polyurethane (TPU) wani nau'in elastomer ne wanda za'a iya ƙera shi ta hanyar dumamawa sannan a narkar da shi ta hanyar narkewa. Yana da kyawawan halaye masu kyau kamar ƙarfi mai ƙarfi, juriya mai ƙarfi, juriyar lalacewa da juriyar mai. Yana da kyakkyawan aikin sarrafawa kuma ana amfani da shi sosai a fannin tsaro na ƙasa, likitanci, abinci da sauran masana'antu. Polyurethane na Thermoplastic yana da nau'ikan guda biyu: nau'in polyester da nau'in polyether, barbashi masu siffar fari ko na columnar, kuma yawansu shine 1.10 ~ 1.25g/cm3. Yawan polyether ya fi na polyester ƙanƙanta. Zafin gilashin canzawa na nau'in polyester shine 100.6 ~ 106.1℃, kuma zafin gilashin canzawa na nau'in polyester shine 108.9 ~ 122.8℃. Zafin karyewar nau'in polyether da nau'in polyester ya fi ƙasa da -62℃, kuma ƙarancin juriyar zafin jiki na nau'in polyester ya fi na polyester kyau. Abubuwan ban mamaki na polyurethane thermoplastic elastomers sune juriyar lalacewa mai kyau, juriyar ozone mai kyau, tauri mai yawa, ƙarfi mai yawa, sassauci mai kyau, juriyar zafi mai ƙarancin zafi, juriyar mai mai kyau, juriyar sinadarai da juriyar muhalli. Tsayin hydrolytic na nau'in ester ya fi na nau'in polyester girma sosai.
