Widely used as a free-radical initiator in polymerization reactions, especially in the production of acrylic and styrenic polymers. It is effective in emulsion, suspension, and solution polymerizations due to its ability to decompose into radicals at moderate temperatures. Commonly applied in the manufacturing of plastics, adhesives, coatings, and synthetic rubbers. Its liquid form enhances handling safety and allows for precise dosing in industrial processes. Also utilized in chemical synthesis where controlled radical generation is required.
