Description

Lithium peroxide is used in air purifiers. It is also used to produce high-purity oxygen. It acts as a catalyst for polymerization of styrene to polystyrene. Further, it serves as a curing agent for special polymers and a source of oxygen in sealed spaces such as submarines and in breathing apparatus.
