UV Absorber UV B-75 CAS 41556-26-7; 125643-61-0; 23328-53-2
UV b-75 feem ntau yog siv rau hauv polyurethane. Kev txhaj tshuaj molding Polyurethane (RIM Polyurethane), piv txwv li, thermoplastic Polyurethane elastomer (TPU). UV b-75 kuj tseem siv tau rau hauv cov nplaum lossis polyurethane coatings xws li tarpaulin, undercloth thiab tawv hluavtaws.
VU b-75 tuaj yeem tiv thaiv kev puas tsuaj ntawm cov khoom polyurethane hauv qab lub teeb lossis huab cua, xws li polyurethane hauv qab, vaj huam sib luag ntsuas, vaj huam sib luag qhov rooj, lub kauj tsheb, daim kab xev kaw qhov rooj thiab qhov rai, lub taub hau thiab tes tuav.
Ntxiv rau, UV b-75 tuaj yeem ntxiv tau yooj yim rau cov khoom polyurethane aromatic thiab aliphatic polyurethane rau cov khoom thermoplastic molding, semi-rigid polyurethane self-laminating foams, thiab lwm yam polyurethane coatings.
UV b-75 siv tau nrog cov xim ntuj lossis lwm yam khoom siv xim, tshwj xeeb tshaj yog rau lub teeb stabilizer ntawm cov khoom saum toj no.
Ua ib qho kua antioxidant nrog kev ua tau zoo heev, UV b-75 muaj qhov zoo ntawm kev muaj peev xwm nchuav thiab pumped, tsis muaj plua plav paug thaum siv thiab luv luv lub sijhawm sib tov. Txhua yam kua tsis precipitate thaum lub sij hawm khaws cia ntawm polyols, txawm tias nyob rau hauv qhov kub qis.
Khaws lub thawv kom kaw ruaj. Tsis txhob noj thiab ua pa.
