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.Reaction txhaj tshuaj molding Polyurethane (RIM Polyurethane), piv txwv li, thermoplastic Polyurethane elastomer (TPU).Ove b-75 kuj tseem siv tau rau hauv cov nplaum lossis polyurethane coatings xws li tarpaulin, undercloth thiab hluavtaws tawv. .
VU b-75 tuaj yeem tiv thaiv kom tsis txhob degradation ntawm polyurethane cov khoom nyob rau hauv lub teeb los yog kev nyab xeeb, xws li polyurethane ib leeg, ntsuas vaj huam sib luag, vaj huam sib luag qhov rooj, lub kauj, lub qhov rooj thiab qhov rais sealing sawb, headrest thiab tuav.
Tsis tas li ntawd, UV b-75 tuaj yeem muab tau yooj yim ntxiv rau cov khoom muaj ntxhiab polyurethane thiab aliphatic polyurethane rau cov khoom siv thermoplastic molding, semi-rigid polyurethane tus kheej laminating foams, thiab lwm yam polyurethane txheej.
UV b-75 tuaj yeem siv nrog cov xim ntuj lossis lwm yam khoom siv xim, tshwj xeeb tshaj yog rau lub teeb stabilizer ntawm cov khoom saum toj no.
Raws li cov kua tshuaj antioxidant nrog kev ua tau zoo, UV b-75 muaj qhov zoo ntawm kev tuaj yeem nchuav thiab nqus, tsis muaj plua plav paug thaum siv thiab siv sijhawm luv luv.Txhua cov kua dej tsis ua rau lub sijhawm khaws cov polyols, txawm tias qhov kub thiab txias. .
Khaws lub thawv kaw kom nruj. Tsis txhob noj thiab nqus pa.
