Thermoplastic Polyester Elastomer (TPEE)-tseem hu ua polyester roj hmab los yog TPC-ET- yog ib txoj kab thaiv copolymer uas muaj cov ntu ntu ntawm polybutylene terephthalate (PBT) thiab cov ntu hloov tau ntawm polyether lossis polyester. Thawj tsim nyob rau hauv 1972 los ntawm DuPont (USA) thiab Toyobo (Nyiv), cov khoom no sib txuas cov elastic zog ntawm cov roj hmab nrog cov yam ntxwv ntawm cov yas. Nws muaj qhov nyuaj ntawm 32-82 Shore D, tiv taus qhov kub thiab txias ntawm -70℃txog 200 degree, thiab nthuav tawm zoo heev tiv thaiv kev qaug zog, cuam tshuam, thiab tshuaj lom neeg corrosion.
Cov khoom ntawm TPEE tuaj yeem raug kho los ntawm kev kho qhov sib piv ntawm nws cov ntu nruj thiab hloov tau yooj yim; tshwj xeeb, nws cov qauv compression yog siab dua li ntawm cov ntaub ntawv polyurethane. Nws tau siv dav hauv cov haujlwm xws li cov khoom siv tsheb (sau npe rau ntau dua 70% ntawm daim ntawv thov), hluav taws xob thiab khoom siv hluav taws xob, thiab cov khoom lag luam. Nws cov ntawv thov tseem ceeb suav nrog kev tsim cov flex-cov khoom tiv taus, xws li hydraulic hoses, kis tau tus mob, thiab lub zog. Xyoo 2025, kev lag luam loj rau TPEE hauv Suav teb tau txog 3.093 billion RMB, thaum lub ntiaj teb kev ua lag luam nce mus txog 10.808 billion RMB; Kev lag luam thoob ntiaj teb tau npaj kom loj hlob mus rau 15.438 billion RMB los ntawm 2032. Ningbo Institute of Materials Technology thiab Engineering tau ua tiav ib qho bio-raws li thiophene dicarboxylate- hom TPEE. Cov khoom siv tshiab no siv poly (1,3-propylene 2,5-thiophenedicarboxylate) raws li nws cov ntu ntu, ua ke nrog polytetrahydrofuran ether saj zawg zog ntu; Nws ua tiav qhov elongation ntawm kev tawg ntawm 760% thiab tensile modulus ntawm 122 MPa, thaum ib txhij muaj ob qho tib si biocompatibility thiab antimicrobial zog.
