Benzoyl Peroxide is an organic peroxide compound used widely as a polymerization initiator and curing agent, available in both powder and paste forms. In industrial applications, it is essential in initiating free-radical polymerization in the production of resins, plastics, and rubbers. It is also used in the crosslinking of unsaturated polyester resins, especially in fiberglass-reinforced plastics. The paste form is typically stabilized in a phlegmatizer like water or plasticizer to ensure safe handling.

Industrial Uses

1. Performance Chemicals

  • Free-Radical Polymerization Initiator: Used to initiate polymerization of styrene, acrylates, and methacrylates. Essential in the manufacture of plastics, resins, and acrylic-based compounds. Provides consistent curing under controlled heat conditions in polymer plants.
  • Hardener for Unsaturated Polyester Resins (UPR): Widely used in combination with accelerators (like cobalt octoate) for crosslinking resins. Applied in FRP products including tanks, panels, automotive parts, and castings. Ensures uniform curing, improved strength, and reduced cycle times in molding processes.

2. Constructions

  • Composite Materials and Structural Laminates: Used in the preparation of fiber-reinforced construction materials and prefabricated composites. Enhances dimensional stability and structural integrity of UPR-based profiles and sheets. Common in production of architectural panels, bathware, and sanitary structures.

3. Paints, Coatings & Adhesive 

  • Curing Agent for Gel Coats and Pigmented Resins: Used in pigmented gel coats for boats, sanitary fittings, and automotive parts. Enables smooth, defect-free curing of thermosetting coating systems. Improves film hardness, chemical resistance, and adhesion properties.
