Gwiritsani ntchito
Chogulitsachi ndi chonyamulira cha UV cholemera kwambiri cha gulu la hydroxypheny benzotriazole, chomwe chimasonyeza kukhazikika kwa kuwala kwa ma polima osiyanasiyana panthawi yogwiritsidwa ntchito.
Ndi yothandiza kwambiri pa ma polima omwe nthawi zambiri amakonzedwa pa kutentha kwambiri monga polycarbonate, polyesters, polyacetal, polyamides, polyphenylene sulfide, polyphenylene oxide, aromatic copolymers, thermoplastic polyurethane ndi polyurethane ulusi, komwe kutayika kwa UVA sikuloledwa komanso kwa polyvinylchloride, styrene homo- ndi copolymers.
Kulongedza ndi Kusunga
