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

UV b-75 amagwiritsidwa ntchito makamaka mu polyurethane.Reaction jekeseni akamaumba Polyurethane (RIM Polyurethane), mwachitsanzo, thermoplastic Polyurethane elastomer (TPU) .Ove b-75 Angagwiritsidwenso ntchito zomatira kapena polyurethane zokutira monga tarpaulin, nsalu zamkati ndi kupanga chikopa .

VU b-75 imatha kuteteza bwino kuwonongeka kwa zinthu za polyurethane pansi pa kuwala kapena nyengo, monga polyurethane sole, gulu la zida, chitseko cha chitseko, chiwongolero, chitseko ndi zenera losindikizira, chitseko chamutu ndi handrail.

Kuphatikiza apo, UV b-75 imatha kuwonjezedwa mosavuta kuzinthu zonunkhira za polyurethane ndi aliphatic polyurethane pazopangira zopangira ma thermoplastic, thovu lokhazikika la polyurethane, ndi zokutira zina za polyurethane.

UV b-75 itha kugwiritsidwa ntchito ndi utoto wachilengedwe kapena zida zina zamitundu, makamaka pakukhazikitsira kuwala kwa zinthu zomwe zili pamwambapa.

Monga antioxidant yamadzimadzi yochita bwino kwambiri, UV b-75 ili ndi ubwino wotha kutsanuliridwa ndi kupopera, yopanda kuipitsidwa ndi fumbi panthawi yogwiritsira ntchito komanso nthawi yochepa yosakaniza. .
