Dilauroyl peroxide (LPO) is widely used as an initiator in polymerization reactions, particularly in the production of plastics and resins. It helps initiate the polymerization process by decomposing into free radicals when heated, which then react with monomers to form polymers. This makes it valuable in the manufacture of materials like PVC, polyethylene, and polystyrene. Additionally, LPO is employed in the curing of unsaturated polyester resins, which are used in fiberglass-reinforced composites for automotive, marine, and construction applications. Its ability to promote cross-linking in polymers also makes it useful in the production of adhesives and coatings. In the cosmetic industry, it is sometimes utilized in small quantities for its stabilizing properties in formulations. However, due to its reactive nature, it must be handled with care to ensure safety.
