Specification
Lub teeb Stabilizer LS 622 (tseem hu ua Hindered Amine Lub Teeb Stabilizer 622)yog lub siab molecular hnyav polymeric hindered amine lub teeb stabilizer (HALS) nrog cov tshuaj npe poly (4-hydroxy-2,2,6,6-tetramethyl-1-piperidineethanol) succinate. Cov khoom no yog oligomer uas muaj txiaj ntsig zoo cuam tshuam cov duab-oxidative degradation ntawm polymers los ntawm cov dawb radical scavenging mechanism.
Piv nrog rau qhov hnyav molecular HALS, LS 622 nthuav tawm qis qis dua, zoo heev kev tsiv teb tsaws, thiab kev tawm tsam. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov ntawv thov uas xav tau kev ua haujlwm siab thiab kev tshem tawm, xws li cov yeeb yaj kiab, fibers, tapes, thiab lwm yam siab - tshwj xeeb - nto- cov khoom siv hauv cheeb tsam.

Nta
LS 622 tuaj yeem tiv thaiv lub teeb ultraviolet, txo cov nyhuv kis ntawm UV teeb; thiab tseem tuaj yeem nqus tau lub zog siab UV lub teeb (wavelength 290 ~ 400 m) muaj zog.
Daim ntawv thov
Lub teeb Stabilizer 292 yog tshwj xeeb tshaj yog tsim rau cov txheej txheej thiab tuaj yeem siv rau hauv ntau yam kev siv xws li tsheb refinish coatings, industrial topcoats, coil coatings, wood stains los yog luam muag xim thiab varnishes, hluav taws xob curable coatings.
LS 622 yog dav haum rau cov nram qab no polymer systems:
| Daim ntawv thov teb | Cov ntaub ntawv tshwj xeeb |
|---|---|
| Polyolefins | PP (Polypropylene), PE (Polyethylene, nrog rau kev txhaj tshuaj molding, rotational molding, films, tapes), TPO |
| Olefin Copolymers | EVA (Ethylene{0}}Vinyl Acetate Copolymer) |
| Styrenics | PS, ABS |
| Engineering Plastics | Polyamide (Nylon), Polyacetal (POM), Polyester |
| Elastomers | Elastomers, Polypropylene / Elastomer Blends |
| Lwm tus | Polyurethane (PU, suav nrog fibers thiab kub yaj nplaum), PVC, Adhesives, Sealants |
Ceeb toom tshwj xeeb:LS 622 kuj pom zoo lub teeb stabilization kev ua tau zoo hauv cov pa roj carbon dub - muaj cov tshuab.
Kev ntsuas kev ua tau zoo thiab kev sib koom ua ke
Siv ib leeg:Raws li qhov hnyav molecular hnyav HALS, nws muab lub sijhawm ntev - tiv thaiv lub teeb ruaj khov, tiv thaiv cov teeb meem zoo li gloss, tawg, blistering, delamination, thiab discoloration.
Siv ua ke nrog UV Absorbers:Tso tawm ib qho tseem ceeb synergistic nyhuv, uas yog tshwj xeeb tshaj yog hais nyob rau hauv pigmented systems.
Siv ua ke nrog rau lwm yam siab Molecular Nyhav HALS:Ua kom muaj kev sib koom ua ke thaum ua ke nrog qhov hnyav molecular HALS xws li LS 944 thiab LS 119.
Siv ua ke nrog Antioxidants:Ntxiv mus, txhim kho thermal stability thiab UV stability
