Zinc Oxide for Rubber
Zinc oxide is important organic chemical material; executive standard: GB/T3185-92; it is insoluble in water; soluble in acid, alkali and ammonium hydroxide; widely used in rubber, foaming,
coating, ceramic, printing ink, enamel, electric cable and paint fields.
Between 50% and 60% of Zinc Oxide use is in the rubber industry. Zinc Oxide along with stearic acid is used in the vulcanization
of rubber, ZnO additive also protect rubber from fungi (see medical applications) and UV light.
