Antioxidant 168 CAS 31570-04-4 Tris (2,4-di-tert-butylphenyl) phosphite
Antioxidant 168 yog ib qho zoo heev phosphite antioxidant. Nws yog ib tug dawb hmoov nyob rau hauv tsos. Nws yooj yim soluble hauv cov kuab tshuaj organic xws li benzene, chloroform thiab cyclohexane. Nws yog me ntsis soluble hauv ethanol, acetone, thiab insoluble hauv dej thiab cawv Solvent, me ntsis soluble hauv esters. Tsawg toxicity, tsis tshua muaj volatility, siab thermal stability, zoo heev hydrolysis tsis kam, thiab muaj peev xwm decompose hydroperoxides generated thaum lub sij hawm thermal ua ntawm polymeric cov ntaub ntawv.Muaj ntau tshaj li ib tug kaum os formulations compounded nrog phenolic antioxidants, uas yog dav siv nyob rau hauv polyolefins (xws li aspolyethylene thiab polypropylene) thiab olefin copolymer, polyamides, polycarbonates, PS resins, PVC, engineering plastics, thiab roj hmab thiab roj av, cov khoom siv polymer xws li ABS resin.
Khaws lub thawv kaw kom nruj. Tsis txhob noj thiab nqus pa.
