DTBP is one of the most stable organic peroxides. It is used as a crosslinking polyethylene, EVA and vulcanization of rubber. It is used as a polymerization initiator at temperature above 100°C. Used as catalyst in polymerization for olefin copolymers and crosslinking agent for unsaturated polyesters. It is also used as fuel additive and chemical intermediate.

Peroxide are powerful oxidizing agents releasing oxygen. Then are widely used as initiators and catalysts for the polymerization process the plastics industry and as disinfectants for cosmetics, detergents, toothpaste and pharmaceuticals.
