Zoo UV Absorber UV P CAS 2440-22-4
UV P yog ib qho zoo polymeric lub teeb stabilizer. Nws tuaj yeem siv dav hauv engineering plastics thiab homologous styrene copolymer, xws li polyester, acrylic resin thiab lwm yam halogen polymers lossis copolymer (xws li vinylene), acetal, cellulose ester thiab lwm yam. UV Palso siv rau elastomers, adhesives, polycarbonate blends, polyurethanes. , lwm yam cellulose esters, thiab epoxy cov ntaub ntawv.
Nws tseem muaj peev xwm nqus tau ultraviolet lub teeb nyob rau hauv thaj tsam ntawm 300-400nm. UV P muaj cov duab zoo tshaj plaws nyob rau hauv lub hnub ci mus ntev.
Khaws lub thawv kaw kom nruj. Tsis txhob noj thiab nqus pa.
