Inzira ya polymer oxydeire ni urunigi rwerekana ubwoko bwa radical. Antioxydants ya plastike ni ibintu bimwe na bimwe, bishobora gufata radicals ikora kandi ikabyara radical idakora, cyangwa ikabora polymer hydroperoxide ikorwa mugikorwa cya okiside, kugirango ihagarike urunigi kandi itinde inzira ya okiside ya polymers. Kugirango polymer ishobore gutunganywa neza kandi ubuzima burambye.
