Zinc peroxide (ZnO2) is a chemical compound used as a bleaching and curing agent. Perhaps its most important use is to promote cross-linking in carboxylated nitrile rubber and other elastomers.<ref>Akiba, M., and A. S. Hashim (1997). "Vulcanization and crosslinking in elastomers". Progress in Polymer Science 22: 475–521. DOI:10.1016/S0079-6700(96)00015-9.</ref>
Conditions/substances to avoid are: water, acids, salts of heavy metals, reducing agents, organic materials, flammable substances and hydrogen peroxide.
