Polycarbonate Diol (PCDL)yog tus hwm- qib tshwj xeeb polyol engineered rau siab -kev ua tau zoo polyurethane systems. Piv nrog cov pa polyester polyol thiab polyether polyol, Polycarbonate Diol (PCDL) muab kev txhim kho ruaj khov thiab ntev - lub sij hawm ruaj khov.
Ua tsaug rau nws cov qauv carbonate pob txha tshwj xeeb, Polycarbonate Diol (PCDL) muab kev tiv thaiv zoo rau hydrolysis, tshav kub, oxidation, thiab tshuaj lom neeg. Cov khoom no ua rau Polycarbonate Diol (PCDL) cov khoom siv zoo tagnrho rau kev thov kev lag luam thiab kev siv tshwj xeeb.

Polycarbonate Diol (PCDL) yog siv dav hauv polyurethane dispersions (PUD) rau siab - dej ua haujlwm - raws li txheej txheej. Piv nrog rau cov pa polyols, PUD systems raws li Polycarbonate Diol (PCDL) pom zoo hydrolysis tsis kam, ua rau lawv zoo tagnrho rau cov chaw ntub dej lossis ntub dej. Cov dispersions no muab cov yeeb yaj kiab zoo heev- tsim cov khoom, muaj zog adhesion rau ntau yam substrates, thiab txhim kho kev puas tsuaj. Tsis tas li ntawd, Polycarbonate Diol (PCDL) txhim kho cov tshuaj tiv thaiv tiv thaiv cov tshuaj ntxuav thiab cov kuab tshuaj, uas yog ib qho tseem ceeb rau cov txheej txheem textile, tawv tiav, thiab txheej ntoo. Nws qhov tsis tshua muaj VOC sib raug zoo kuj tseem txhawb nqa cov qauv kev sib raug zoo ntawm ib puag ncig, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov txheej txheem txheej txheej.
Hauv cov ntawv thov thermoplastic polyurethane (TPU), Polycarbonate Diol (PCDL) ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov kav ntev thiab kev ua haujlwm. TPU cov ntaub ntawv uas tsim nrog Polycarbonate Diol (PCDL) qhia tau hais tias zoo heev mechanical zog, yooj, thiab ntev -lub sij hawm resilience nyob rau hauv dynamic kev nyuaj siab. Piv nrog polyester- thiab polyether-raws li TPU, PCDL-raws li TPU muaj kev txhim kho zoo heev rau hydrolysis, tshav kub aging, thiab UV raug. Qhov no ua rau nws tshwj xeeb tshaj yog haum rau kev thov xws li cables, films, hoses, thiab wearable devices. Tsis tas li ntawd, Polycarbonate Diol (PCDL) pab txhawb kom zoo dua pob tshab thiab qhov zoo ntawm qhov chaw, uas yog qhov tseem ceeb rau siab -kawg TPU cov khoom siv hauv cov khoom siv hluav taws xob thiab cov khoom siv.
Polycarbonate Diol (PCDL) yog dav siv nyob rau hauv hluavtaws tawv resins rau hwm PU tawv ntau lawm. Polyurethane systems raws li Polycarbonate Diol (PCDL) muab qhov sib npaug zoo dua ntawm softness, elasticity, thiab txhua yam muaj zog, ua rau cov tawv nqaij ntau dua -zoo li xav. Nws zoo heev hydrolysis tsis kam ua kom ntev - lub sij hawm durability, tshwj xeeb tshaj yog nyob rau hauv khau, automotive interiors, thiab rooj tog zaum upholstery raug rau ya raws thiab kub hloov. Tsis tas li ntawd, Polycarbonate Diol (PCDL) txhim khu kev tiv thaiv kom daj thiab kev laus, ua kom zoo nkauj zoo nkauj lub sijhawm. Cov txiaj ntsig no ua rau nws yog ib qho tseem ceeb raw khoom rau siab -kawg hluavtaws tawv tsom rau cov khoom kim heev thiab kev ua tau zoo- tsav kev lag luam.
