Organic peroxides are most widely used in the chemical, plastic and rubber industries. They act as initiators for the free radical polymerization of monomers to synthesize thermoplastic polymers, and as agents for curing thermosetting polyester resins and cross-linked elastomers and polyethylene. Organic peroxides are used as a source of free radicals in many organic synthesis.

2-Butanone peroxide is the hardener of glass fiber and reinforced plastics, and also the hardener of unsaturated polyester resin. Cyclohexanone peroxide is the catalyst for hardening some glass fiber resins; Bleaching agent for flour, vegetable oil, fat and wax; And the polymerization agent in the plastic industry and the curing agent in the rubber industry. Lauroyl peroxide can be used in cosmetics and pharmaceutical industry, and also can be used as a burning agent for acetate yarn. In addition to being used as polymerization catalyst, tert butyl peroxide is also used as ignition promoter of diesel fuel.

Benzoyl peroxide is mainly used in polymer industry to initiate free radical polymerization and copolymerization of vinyl chloride, styrene, vinyl acetate and acrylic resin. It is also used to cure thermosetting polyester resin and silicone rubber and to harden certain glass fiber resins. Benzoyl peroxide is used to treat acne. It is the preferred bleaching agent for flour, and has been used for bleaching cheese, vegetable oil, wax, fat, etc. Cumene hydroperoxide is used to make phenol and acetone. Peracetic acid is a bactericide and bactericide, especially used in food processing. It is also used as a bleaching agent for textiles, paper, oil, wax and starch, and as a polymerization catalyst.

Hydrogen peroxide has many uses, most of which derive from its characteristics as a strong oxidant or bleach. It is also used as a reagent for the synthesis of compounds. Different grades of hydrogen peroxide have different uses: 3% and 6% solutions are used for medicinal and cosmetic purposes; 30% solution is used for laboratory reagent, 35% and 50% solutions are used for most industrial applications, 70% solution is used for some organic oxidation applications, and 90% solution is used for some industrial applications and for military and aerospace propellant programs. More than 90% of solutions are used for professional military purposes.

Hydrogen peroxide is used to produce glycerin, plasticizer, bleach, medicine, cosmetics, desiccant of fat, oil and wax, and amine oxide for household tableware detergent. It is used in the textile industry to bleach textiles, especially cotton, and in the pulp and paper industry to bleach mechanical wood pulp. In mining, hydrogen peroxide is used to increase the solubility of uranium in leaching solution. It can also be used for metal etching, oxidation and metal surface treatment in the electronic industry. In addition, hydrogen peroxide is a bactericide in the food industry and a source of oxygen in respiratory protective equipment.
