The peroxide crosslinking agent mainly realizes the crosslinking reaction by introducing free radicals or reactive oxygen atoms. It decomposes in rubber to generate free radicals, which interact with the polymer chains and initiate the crosslinking reaction. This crosslinking reaction connects different polymer chains together, forming a three-dimensional network structure, thereby improving the material's strength, abrasion resistance, and chemical corrosion resistance.

Peroxide crosslinking agents are widely used in the production of rubber products, such as rubber seals, wire and cable insulation materials, and self-healing tire inner linings etc.
