Polymer science is continuously evolving, driven by the need for materials with enhanced properties tailored for specific applications. Crosslinking is a fundamental process that transforms linear or branched polymer chains into a three-dimensional network, dramatically altering their physical and chemical characteristics. Organic peroxides are a class of compounds widely used as initiators for this process. NINGBO INNO PHARMCHEM CO.,LTD. plays a vital role in supplying these essential chemical agents, such as their high-performance Organic Peroxide Initiator, to industries worldwide.

The Organic Peroxide Initiator, a 50% formulation on an inert carrier system in powder form, exemplifies the sophisticated chemistry involved in modern polymer modification. Its bifunctional nature allows it to effectively initiate the crosslinking of various polymers, including natural and synthetic rubbers, and polyolefins. The process begins with the thermal decomposition of the peroxide molecule, which cleaves to form highly reactive free radicals. These radicals then abstract hydrogen atoms from the polymer chains, creating polymer radicals. The subsequent combination of these polymer radicals results in the formation of stable covalent crosslinks.

Understanding the kinetics of this process is crucial for optimal results. The Organic Peroxide Initiator offers excellent scorch safety, meaning that premature crosslinking during the initial mixing phase is minimized. This is attributed to its controlled decomposition rate and a relatively high safe processing temperature of 135°C. This characteristic allows for thorough dispersion of the initiator within the polymer matrix before significant crosslinking occurs, leading to more uniform final properties. The typical crosslinking temperature of 175°C ensures that once the material reaches this temperature, the crosslinking reaction proceeds efficiently, achieving a high degree of cure (t90 of approximately 12 minutes).

The scientific advantage of using such initiators lies in their ability to create carbon-carbon crosslinks. These C-C bonds are generally stronger and more thermally stable than the C-S bonds formed during traditional sulfur vulcanization, leading to polymers with superior heat resistance, mechanical strength, and aging properties. This makes them ideal for demanding applications where materials are subjected to harsh conditions.
