TPU ua npuas ncauj, lossis thermoplastic polyurethane ua npuas ncauj, yog cov khoom siv polymer tshiab uas tau nyiam cov xim vim nws cov khoom tshwj xeeb. Cov khoom no muaj ntau cov elastic, hnav TPU ua npuas ncauj hlaws.
Tom qab ua npuas dej, TPU npuas nthuav dav rau {{{0}}} npaug ntawm nws qhov qub ntim, nrog qhov pore loj ntawm 30-300 microns. Nws muaj qhov ceev tsawg heev ntawm 0.15-0.25 grams ib cubic centimeter thiab nws qhov hnyav yuav luag imperceptible. Vim yog cov khoom no, nws feem ntau muab piv rau "pob kws."
TPU foaming overcomes lub shortcomings ntawm tsoos TPU cov ntaub ntawv xws li hnyav hnyav, siab hardness, thiab tsis zoo poob siab absorbs. Tsis tas li ntawd, nws yog sib dua, breathable, ib puag ncig tus phooj ywg, hnav-resistant, elastic heev thiab resistant rau yellowing.
TPU ua npuas ncauj yog dav siv hauv khau khoom tsim thiab muaj ob qho tib si zoo nkauj thiab ruaj khov. Ntau lub npe nrov thoob ntiaj teb kev ua kis las khau hom siv TPU ua npuas ncauj cov ntaub ntawv ua insoles thiab outsole.
Hauv cov txheej txheem tsim khoom, TPU kub yaj nplaum nplaum feem ntau yog siv los khi cov ntaub ntawv TPU ua npuas ncauj. Txij li TPU kub yaj nplaum zaj duab xis thiab TPU ua npuas ncauj yog cov khoom siv tib yam, ntau qhov zoo ntawm TPU npuas tuaj yeem khaws cia.
