Anti oxidant

. Rubbers generally are subject to such changes that occur in the course of time and can lead to partial or complete destruction. Possible consequences are depolymerization, fatigue, brittleness, cracks and even disintegration. The resistance of a rubber article to oxygen, ozone and other reactive substances is determined mainly by the elastomer on which the compound is based and by the chemicals that are added to retard the destructive processes. Unsaturated groups in the rubber molecule are the reason for the rubber's sensitivity to oxygen, which increases with temperature. If catalysts of oxidation (known as rubber poisons) are present, aging is rapid. The results are hardening and embrittlement, crazing effects and fatigue. Ozone or dynamic stress (fatigue) lead to cracking on the surface of the rubber article. Antioxidants are chemicals which protect the vulcanizates against damaging external influences
