magnesium oxide’s uses in rubber compounds

vulcanization and aging of rubber articles. Almost all CR compounds are vulcanized with zinc oxide and MgO with or without accelerators. During vulcanization and storage, chloride radicals and hydrogen chloride are created. These chloride-containing compounds can decompose the polymer chain and/or combine with zinc to produce zinc chloride.
