Daim ntawv thov
Antixoidant 245 yog ib yam ntawm cov txiaj ntsig zoo asymmetric phenolic antioxidant, thiab nws cov yam ntxwv tshwj xeeb muaj cov tshuaj tiv thaiv kab mob siab, tsis muaj zog, tsis kam mus rau oxidation xim, muaj txiaj ntsig zoo nrog cov tshuaj antioxidant (xws li monothioester thiab phosphite ester), thiab muab cov khoom zoo huab cua. tiv thaiv thaum siv nrog lub teeb stabilizers. Antioxidant 245 feem ntau yog siv los ua cov txheej txheem thiab lub sijhawm ntev stabilizer rau styrene polymer xws li HIPS, ABS, MBS, thiab engineering thermoplastics zoo li POM thiab PA, thaum nws tseem ua haujlwm kawg ntawm cov saw hauv PVC polymerization. Tsis tas li ntawd, cov khoom lag luam tsis cuam tshuam rau cov tshuaj tiv thaiv polymer. Thaum siv rau HIPS thiab PVC, nws tuaj yeem muab ntxiv rau hauv monomers ua ntej polymerization.
Ntim thiab khaws cia
Ntim: 25kg / hnab
Cia: ruaj khov hauv cov khoom. Tsis muaj qhov tshwj xeeb xav tau tab sis khaws qhov cua thiab deb ntawm dej thiab kub siab.
