UV Absorber UV-234

Kufotokozera Kwachidule:

UV-234 ndi high molecular weight UV absorber ya hydroxypheny benzotriazole kalasi, kusonyeza kukhazikika kwapadera kwa kuwala kwa ma polima osiyanasiyana pakugwiritsa ntchito kwake. Ndiwothandiza kwambiri kwa ma polima omwe amakonzedwa pa kutentha kwakukulu monga polycarbonate, polyesters, polyacetal, polyamides, polyphenylene sulfide, polyphenylene oxide, onunkhira copolymers, thermoplastic polyurethane ndi polyurethane ulusi, kumene kutayika kwa UVA sikuloledwa komanso polyvinylchloride, styrene homo- ndi copolymers.

Kugwiritsa ntchito

Izi ndi mkulu maselo kulemera UV absorber wa hydroxypheny benzotriazole kalasi, kusonyeza kwambiri kuwala bata zosiyanasiyana ma polima pa ntchito yake.It kwambiri zothandiza ma polima nthawi zambiri kukonzedwa pa kutentha kwambiri monga polycarbonate, poliyesitala, polyacetal, polyamides, polyphenylene. sulfide, polyphenylene oxide, zonunkhira za copolymers, thermoplastic polyurethane ndi polyurethane fibers, kumene kutaya kwa UVA sikuloledwa komanso polyvinylchloride, styrene homo- ndi copolymers.
