Dab tsi yogThermoplastic Polyurethane (TPU)?
Nyob rau hauv cov thermoplastic elastomers, thermoplastic polyurethanes (TPU) tsim ib tug subcategory. Raws li txoj cai, cov ntaub ntawv no yog thaiv copolymer ntawm polyethers lossis polyesters nrog classic polyurethanes.
Cov khoom sib txawv feem ntau yog hloov kho thaum lub sijhawm polymerization los ntawm kev sib txuas cov khoom sib txawv. Nyob rau hauv tsawg zaus, tom ntej compounding nrog ntau yam additives kuj yog ua.
Dab tsi yog cov khoom siv TPU muaj?
TPU cov ntaub ntawv yog cov yam ntxwv feem ntau los ntawm lawv cov neeg kho tshuab siab zog thiab ua haujlwm zoo heev.
Plastics los ntawm TPU chav kawm qhia tau zoo tiv thaiv rau ntau yam tsis-polar tshuaj. Nyob rau hauv sib piv, muaj ib co rhiab heev ntawm cov ntaub ntawv hais txog cov khoom degradation nyob rau hauv kev sib cuag nrog dej thiab aqueous daws, tshwj xeeb tshaj yog nyob rau hauv high kub. Txhawm rau kom tsis txhob muaj cov khoom puas tsuaj, nws yog qhov tseem ceeb kom qhuav TPU compounds ua ntej ua. Qhov no kuj txhawb cov txheej txheem ntawm cov ntaub ntawv.
Nyob ntawm cov chaw tsim khoom, TPUs kuj tau tsim rau cov neeg siv khoom lag luam. Cov ntaub ntawv tuaj yeem ua xim, thiab qee cov tuam txhab lag luam kuj tseem muaj TPU translucent.
Abrasion tsis kam
Mechanical zog
Tsawg kub hloov tau
Thaum tshav kub kub laus
Kev tiv thaiv rau ntau yam tsis-polar tshuaj
Kev txhaj tshuaj
Puas yog TPU tawv lossis mos?
Qib hardness ntawm thermoplastic polyurethanes feem ntau yog nruab nrab ntawm 60 Shore A thiab 80 Shore D. Piv nrog rau cov khoom siv TPS, TPU cov ntaub ntawv yog qhov nyuaj thiab tsis tshua muaj kev sib tw ncaj qha.
