Daim Ntawv Thov
Antixoidant 245 yog ib hom tshuaj antioxidant asymmetric phenolic zoo heev, thiab nws cov yam ntxwv tshwj xeeb suav nrog kev ua haujlwm zoo antioxidation, tsis tshua muaj volatility, tiv taus oxidation xim, muaj txiaj ntsig zoo synergistic nrog tus pab antioxidant (xws li monothioester thiab phosphite ester), thiab muab cov khoom zoo tiv taus huab cua thaum siv nrog lub teeb stabilizers. Antioxidant 245 feem ntau yog siv ua cov txheej txheem thiab lub sijhawm ntev stabilizer rau styrene polymer xws li HIPS, ABS, MBS, thiab engineering thermoplastics xws li POM thiab PA, thaum nws kuj ua haujlwm ua qhov kawg ntawm saw hlau hauv PVC polymerization. Tsis tas li ntawd, cov khoom tsis muaj kev cuam tshuam rau cov tshuaj tiv thaiv polymer. Thaum siv rau HIPS thiab PVC, nws tuaj yeem ntxiv rau hauv monomers ua ntej polymerization.
