Gusaba
Antixoidant 245 ni ubwoko bwa antioxydants ya asimmetrike ikora cyane, kandi ibiranga umwihariko byayo birimo antioxydants ikora neza, ihindagurika rike, kurwanya amabara ya okiside, ingaruka zikomeye hamwe na antioxydeant (nka monothioester na fosifite ester), no guha ibicuruzwa ibihe byiza. kurwanya iyo bikoreshejwe hamwe na stabilisateur yumucyo. Antioxidant 245 ikoreshwa cyane nkibikorwa hamwe na stabilisateur yigihe kirekire kuri styrene polymer nka HIPS, ABS, MBS, hamwe nubushakashatsi bwa termoplastique nka POM na PA, mugihe nayo ikora ihagarika urunigi muri polymerisation ya PVC. Mubyongeyeho, ibicuruzwa nta ngaruka bigira kuri polymer reaction. Iyo ikoreshwa kuri HIPS na PVC, irashobora kongerwaho muri monomers mbere ya polymerisation.
