Lub teeb Stabilizer-944 CAS 70624-18-9 yog dab tsi?

Lub teeb stabilizer UV-944 muaj kev tiv thaiv zoo, tshwj xeeb tshaj yog tsim rau cov khoom nyias, xws li fibers thiab films; Nws tuaj yeem txhim kho cov thermal oxygen aging kuj ntawm cov khoom. Lub teeb stabilizer HS-944 yog dawb rau lub teeb daj los yog hmoov, melting point 100-135 ° C, molecular hnyav 2000-3100, nrog zoo heev compatibility, extraction kuj thiab tsis tshua muaj volatility. Txij li UV-944 yog cov txheeb ze molecular loj stabilizer, thiab cov molecule tsuas muaj ib tug loj npaum li cas ntawm methylate, nws yog ruaj khov thaum kho nrog kub oxygen.
