Crosslinking Catalysts / Accelerators / Initiators

Crosslinking catalysts, accelerators, and initiators are essential additives used in the plastics industry to enhance the properties of polymers by promoting crosslinking reactions. These compounds typically appear as powders, liquids, or gels that integrate smoothly into polymer formulations. Functionally, they improve the material's mechanical strength, thermal stability, and chemical resistance. Key features include their ability to tailor the physical properties of plastics for specific applications, such as in automotive parts, electrical insulation, and medical devices. 

Alternatives to crosslinking catalysts include physical crosslinking methods, such as radiation or thermal treatments. A notable trend in the industry is the development of advanced crosslinking systems that offer faster curing times and lower processing temperatures. Sub-types of crosslinking additives include peroxide initiators, sulfur accelerators, and silane coupling agents.
