Choyamwitsa UV UV B-75 CAS 41556-26-7; 125643-61-0; 23328-53-2

UV b-75 imagwiritsidwa ntchito kwambiri mu polyurethane. Kuyika jekeseni wa reaction Polyurethane (RIM Polyurethane), mwachitsanzo, thermoplastic Polyurethane elastomer (TPU). Ove b-75 ingagwiritsidwenso ntchito mu zomatira kapena zophimba za polyurethane monga tarpaulin, undercloth ndi chikopa chopangidwa.

VU b-75 imatha kuletsa kuwonongeka kwa zinthu za polyurethane pansi pa kuwala kapena nyengo, monga polyurethane sole, zida, chitseko, chiwongolero, chitseko ndi zenera, chopumira mutu ndi chogwirira.

Kuphatikiza apo, UV b-75 ikhoza kuwonjezeredwa mosavuta ku aromatic polyurethane ndi aliphatic polyurethane products za thermoplastic molding products, semi-rigid polyurethane self-laminating foams, ndi zina polyurethane coverings.

UV b-75 ingagwiritsidwe ntchito ndi utoto wachilengedwe kapena zinthu zina zamitundu, makamaka pokonza kuwala kwa zinthu zomwe zili pamwambapa.

Monga antioxidant yamadzimadzi yokhala ndi ntchito yabwino kwambiri, UV b-75 ili ndi ubwino woti imatha kutsanulidwa ndi kupopedwa, yopanda fumbi loipa panthawi yogwiritsidwa ntchito komanso nthawi yochepa yosakaniza. Zakumwa zonse sizimagwa panthawi yosungira ma polyol, ngakhale kutentha kochepa.
