Specification
Lub teeb Stabilizer LS 770 (tseem hu ua Hindered Amine Lub Teeb Stabilizer 770)yog ib qho hnyav molecular hindered amine lub teeb stabilizer (HALS) nrog cov tshuaj npe bis (2,2,6,6-tetramethyl-}4-piperidyl) sebacate. Cov khoom no muaj txiaj ntsig zoo inhibits photo-oxidative degradation ntawm polymers los ntawm cov dawb radical scavenging mechanism, muab kev ruaj ntseg zoo rau lub sijhawm ntev rau cov ntaub ntawv polymer. Nws yog ib qho ntawm feem ntau siv lub teeb stabilizers muaj hnub no.
LS 770 yog tshwj xeeb tshaj yog haum rau lub teeb stabilization tiv thaiv ntawm cov khoom tuab, thaum tseem muaj kev ua tau zoo nyob rau hauv siab - tshwj xeeb - nto- cheeb tsam cov khoom xws li zaj duab xis thiab tapes. Nws yog ib qho zoo tagnrho lub teeb stabilization tov rau polyolefins, styrenic polymers, polyurethanes, thiab engineering yas.

Kev ntsuas kev ua tau zoo:
Thaum siv ua ke nrog cov tshuaj tua kab mob antioxidant, nws tuaj yeem txhim kho kev laus thaum tshav kub kub.
Thaum siv ua ke nrog UV absorbers (xws li UV 326, UV 327, UV 329), nws nthuav tawm cov txiaj ntsig zoo, ntxiv dag zog rau lub teeb stabilization.
Kev nyab xeeb & kev tswj hwm
Toxicity Information:Cov khoom no muaj toxicity tsawg thiab tsis yog - khaus rau tib neeg daim tawv nqaij.
Regulatory Status:Cov khoom no raug tso cai siv rau hauv polyolefin plastics npaj rau kev sib cuag zaub mov hauv cov tebchaws xws li Nyiv, Canada, thiab Tebchaws Meskas (qhov kev siv siab tshaj plaws: 0.5% hauv Asmeskas thiab Nyiv; 0.35% hauv Canada).
Kev txwv tsis pub siv:Tsis haum rau siv nyob rau hauv daim ntawv thov uas muaj kev sib cuag nrog cov zaub mov ncaj qha, los yog nyob rau hauv cov khoom uas nkag mus rau hauv cov mucous daim nyias nyias, abraded daim tawv nqaij, los yog implanted rau hauv tib neeg lub cev.
