Silicone Flame Retardant Additive
Silicone flame retardant additive is a polysiloxane-based compound that functions in the condensed phase by promoting formation of a cohesive, ceramic-like silica char layer during combustion. Unlike halogen or phosphorus-based FRs, silicone additives reduce heat release rate and smoke production while maintaining excellent electrical insulation and mechanical properties. They are particularly valued in high-performance engineering plastics and wire and cable applications.
