Cov Khoom Siv UV Zoo UV P CAS 2440-22-4
UV P yog ib qho tshuaj polymeric light stabilizer zoo. Nws tuaj yeem siv dav hauv cov yas engineering thiab homologous styrene copolymer, xws li polyester, acrylic resin thiab lwm yam halogen polymers lossis copolymers (xws li vinylene), acetal, cellulose ester thiab lwm yam. UV P kuj siv rau elastomers, adhesives, polycarbonate blends, polyurethanes, lwm yam cellulose esters, thiab epoxy cov ntaub ntawv.
Nws kuj muaj peev xwm nqus tau lub teeb ultraviolet hauv qhov ntau ntawm 300-400nm. UV P muaj qhov ruaj khov zoo dua nyob rau hauv lub hnub ci ntev.
Khaws lub thawv kom kaw ruaj. Tsis txhob noj thiab ua pa.
