Chimassorb 944 Cas 71878-19-8 yog dab tsi?

Chimassorb 944 (CAS 71878-19-8) yog ib qho tshuaj amine hindered light stabilizer (HALS) uas muaj molecular weight siab.

UV Absorber 944 yog ib qho polymerized high-molecular-weight hindered amine light stabilizer, uas muaj qhov tsis tshua muaj volatility, migration resistance, thiab high-temperature resistance. Cov hindered amine pawg hauv cov qauv tshuaj ntawm UV 944 tuaj yeem ntes tau cov free radicals, yog li ua lub luag haujlwm hauv kev ruaj khov ntawm lub teeb.

Polymeric high-efficiency hindered amine lub teeb stabilizer, qis volatilization, qis migration, thermal stability thiab anti-oxidation nyhuv, synergistic nrog antioxidants thiab UV absorbers. UV Absorber 944 tuaj yeem siv rau polyolefins, olefin copolymers, tab sis kuj rau polyphenylene ether complexes, polyoxymethylene, amides, mos thiab tawv PVC thiab PVC blends.
