Siv
Tetrakis(2,4 - di - tert - butylphenyl) [1,1'-biphenyl]-4,4'-diylbis(phosphonite) ua hauj lwm pab raws li ib tug pab antioxidant. Nws tuaj yeem hnov mob nrog cov hydroperoxides tsim thaum lub sijhawm ua thiab nws pib-oxidation ntawm polymers, yog li tiv thaiv kev degradation los ntawm kev ua. Ntxiv mus, nws tuaj yeem ua rau muaj kev sib koom ua ke nrog lub ntsiab antioxidant. Nws daim ntawv thov thaj chaw npog polyolefins, olefin copolymer zoo li polyethylene, polypropylene, polybutene, ethylene-vinyl acetate copolymers, polycarbonate, polyacetal, polyamide, thiab lwm yam. Nws cov tshuaj antioxidant kuj tuaj yeem siv rau hauv polyester, styrene homopolymer, thiab copolymer khoom, adhesives, ntuj thiab hluavtaws tackifiers, elastomers xws li BR, SEBS, SBS, thiab lwm yam organic substrates. Tsis tas li ntawd, nws tuaj yeem siv ua ke nrog Tinuvin thiab Chimassorb series lub teeb stabilizers.
