Chemical Properties:

Polycarbonateyog ib qho amorphous, tasteless, odorless, non-toxic pob tshab thermoplastic polymer, muaj cov khoom zoo heev, thermal thiab hluav taws xob, tshwj xeeb tshaj yog cuam tshuam, zoo toughness, creep me me, cov khoom loj yog ruaj khov. Nws muaj kev cuam tshuam lub zog ntawm 44kj / mz, tensile zog> 60MPa. polycarbonate kub tsis kam yog qhov zoo, tuaj yeem siv tau ntev ntawm - 60 ~ 120 ℃, kub deflection kub 130 ~ 140 ℃, iav hloov kub ntawm 145 ~ 150 ℃, tsis muaj qhov pom tseeb melting point, hauv 220 ~ 230 ℃ yog lub xeev molten. Thermal decomposition kub> 310 ℃. Vim lub rigidity ntawm cov saw hlau molecular, nws cov viscosity yaj yog ntau dua li ntawm cov thermoplastics.

Daim ntawv thov:

Peb qhov kev siv loj ntawm PC engineering plastics yog iav sib dhos kev lag luam, kev lag luam tsheb thiab hluav taws xob thiab hluav taws xob kev lag luam, ua raws li kev lag luam machinery qhov chaw, optical discs, ntim, computer thiab lwm yam khoom siv hauv chaw ua hauj lwm, kev kho mob thiab kev kho mob, zaj duab xis, leisure thiab tiv thaiv cov cuab yeej, thiab lwm yam. PC siv tau raws li lub qhov rais thiab qhov rooj iav, PC laminate yog dav siv nyob rau hauv cov tsev txhab nyiaj, embassies, kev tiv thaiv cov qhov rais, kev ruaj ntseg cov chaw rau pej xeem. cov khw muag khoom thiab cov iav mos mos.
