Dialkyl Peroxides & Perketals are key organic peroxides that serve as high-temperature crosslinking agents and initiators for polymers. They decompose to generate free radicals, driving the vulcanization of rubber and the crosslinking modification of plastics.
Dialkyl Peroxides & Perketals are a class of high-efficiency organic peroxides that function primarily as high-temperature initiators and crosslinking agents. By generating free radicals upon thermal decomposition, they enable the crosslinking of polymer chains, which is essential for rubber vulcanization and plastic modification. These products are widely used in industries that demand enhanced heat resistance, mechanical strength, and durability in polymeric materials.
We provide a comprehensive portfolio designed for both standard crosslinking processes and specialized high-performance applications:
