Polycarbonate diols yog ib hom polyols nrog cov khoom zoo heev, thiab lawv cov saw hlau molecular muaj cov carbonate-raws li rov ua haujlwm. Nyob rau hauv xyoo tas los no, lawv raug suav hais tias yog cov khoom siv raw rau tiam tshiab ntawm thermoplastic polyurethane elastomers. Yog li ntawd, raws li qhov muag muag, nws muaj kev ua tau zoo hauv txhua yam ntawm polycarbonized TPU synthesized nrog isocyanate thiab saw extender.
Piv nrog polyester TPU, nws tsis tsuas yog muaj lub zog siab, siab kub tsis kam thiab lwm yam ntxwv, tab sis kuj muaj hydrolysis zoo heev. Piv nrog polyether TPU, nws tsis tsuas yog muaj kev ua haujlwm zoo hydrolysis, tab sis kuj muaj zog dua, zoo dua kub ua hauj thiab zoo oxidation stability.
Vim nws txoj kev ua tau zoo heev, nyob rau xyoo tas los no, polycarbonized TPU tau siv ntau thiab ntau dua hauv kev tsim khoom, cov ntaub ntawv kho mob thiab lwm yam. Siv nws cov hnav tsis kam, siab zog, zoo kub tsis kam, hydrolysis tsis kam, nws tuaj yeem siv los ua cov log tsheb hauv qab dej thiab lwm yam khoom tshwj xeeb. Siv nws cov hydrolysis tsis kam, siab zog, oxidation tsis kam, thiab lwm yam, nws tuaj yeem tsim tshwj xeeb chlorine resistant kav thiab lwm yam khoom lag luam. Nrog nws zoo heev oxidation kuj thiab stability nyob rau hauv tib neeg lub cev, nws yuav siv tau raws li ib tug tshiab hom kev kho mob cog khoom.
Nrog rau ntau xyoo ntawm kev tshawb fawb kev loj hlob thiab kev tsim khoom, Miracll tuaj yeem ruaj khov tsim 80A-95A hardness series ntawm Polycarbonate TPU xws li C80, C85, C90, C95.
Nyob rau hauv lub neej yav tom ntej, peb yuav tsim cov ntaub ntawv zoo tshaj plaws tshiab raws li cov hom phiaj sib txawv thiab ib puag ncig.
