Application
● This compound is widely used as a radical initiator in polymerization processes. It also serves as a vulcanizing agent in rubber manufacturing and as a bleaching agent in various industrial applications, due to its strong oxidative properties.
● This compound is one of the most commonly used radical initiators, frequently applied in the polymerization of acrylates. It works as an initiator for styrene and styrene copolymers and is often combined with other initiators like tert-butyl peroxybenzoate (LQ-TBPB) for enhanced performance.
● In unsaturated polyester resins, it is used as a curing agent at medium to low temperatures, providing consistent results in the curing process.
● As a vulcanizing agent, BPO is essential in the production of diene-based rubbers, contributing to the material's strength and flexibility.
● Additionally, it serves as an important bleaching agent for flour and a decolorizing agent for vegetable oils in the food and processing industries.
