Sebenzisa
Le mveliso yi-light stabilizer esebenza kakuhle, ekwaziyo ukufunxa imitha ye-UV engama-240-340 nm ubude bayo kunye neempawu zombala okhanyayo, ezingenatyhefu, ezihambelana kakuhle, ezihamba kancinci, ezilula ukucutshungulwa njl. Ingakhusela i-polymer kangangoko, inceda ekunciphiseni umbala. Ingaphinda ilibazise ukutyheli kwaye ithintele ukulahleka komsebenzi wayo womzimba. Isetyenziswa kakhulu kwi-PE, PVC, PP, PS, PC organic glass, polypropylene fiber, ethylene-vinyl acetate njl. Ngaphezu koko, inefuthe elihle kakhulu lokuzinza kokukhanya kwi-phenol aldehyde yokomisa, i-varnish yotywala kunye ne-acname, i-polyurethane, i-acrylate, i-expoxnamee njl.
