Used primarily as a radical initiator in polymerization processes, especially in the production of low-density polyethylene (LDPE) and other vinyl polymers. It enables controlled initiation of free radical reactions at elevated temperatures (decomposition range approximately 120–160 °C), making it suitable for high-pressure and solution-phase polymerizations. Its decomposition generates radicals efficiently, promoting chain growth in plastics manufacturing. Also applied in crosslinking of elastomers and curing of unsaturated polyester resins. Preferred in processes requiring a balance between reactivity and thermal stability due to its moderate decomposition rate. Offers high radical yield and low residue after decomposition, resulting in high-purity final products.
