Initiators

Initiators are reactive chemicals that trigger polymerization, decomposition, or catalytic reactions by generating radicals, ions, or active species under thermal, photochemical, or redox conditions. They include peroxides, azo compounds, redox initiators, photo-initiators, and organometallic complexes used across polymer manufacturing, coatings, adhesives, elastomers, and composite fabrication. Their decomposition kinetics, activation energy, and compatibility with monomers determine reaction rate, molecular-weight distribution, and polymer architecture. Initiators are critical for achieving controlled polymerization, improving curing efficiency, and enabling advanced material properties. Modern applications increasingly require low-temperature, low-odor, high-selectivity, and environmentally compliant initiator technologies.
