TPU, high -kev ua tau zoo polymer, tau tshwm sim nyob rau hauv kev kho mob kev lag luam nyob rau hauv xyoo tas los no.Nws lub cev thiab tshuaj lom neeg lub zog ua rau nws plays lub luag hauj lwm tseem ceeb nyob rau hauv kev kho mob teb.TPU (thermoplastic polyurethane elastomer) yog ib tug siab -kev ua tau zoo polymer nrog siab zog, siab toughness, hnav tsis kam, roj kuj thiab lwm yam yam ntxwv ntawm kev kho mob txoj hauj lwm, ua rau nws ib tug tseem ceeb txoj hauj lwm. Tsis tshua muaj kub kev ua tau zoo tau nthuav dav ntawm daim ntawv thov.Thermoplastic polyurethane elastomer (TPU) yog ib qho tshwj xeeb elastomer nrog cov khoom zoo tag nrho xws li lub zog siab, siab tawv, hnav tsis kam, thiab roj tsis kam. Field.TPU tuaj yeem raug cais raws li cov txheej txheem sib txawv.Piv txwv li, raws li cov qauv muag muag, TPU tuaj yeem muab faib ua hom polyester, polyether hom thiab butadiene hom, uas muaj cov pab pawg sib txawv.Ib yam, raws li cov qauv nyuaj, TPU tuaj yeem muab faib ua aminoester hom thiab aminoester urea hom.In practical applications. lub zog, hydrolysis tsis kam thiab siab resilience, thaum polyester TPU nthuav tawm zoo tensile zog, flexural zog thiab kev sib txhuam tsis kam.
Kev faib tawm ntawm TPU hauv kev kho mob
Zoo li lwm yam polyurethane, TPU kuj muaj cov yam ntxwv ntawm siab modulus, siab zog, siab elongation thiab siab elasticity.Tam sim no, nws kuj pom zoo hnav tsis kam, roj kuj, tsis kub tsis kam thiab aging kuj.Tshwj xeeb, nws siab tensile zog, loj elongation thiab tsis tshua muaj deformation tus nqi ntawm ntev -lub sij hawm compression nyob rau hauv ntau yam kev kho mob ntawm TPU muaj ib tug prospected daim ntawv thov. Raws li cov yam ntxwv sib txawv thiab kev siv, xws li rau catheters, adhesives, pob qij txha, thiab lwm yam.Cov hom muaj xws li aliphatic polyetheramines, aromatic polyurethane, thiab lwm yam., Txhua yam ntawm TPU qhia txawv biocompatibility thiab lub cev muaj zog.
