Thermoplastic Polyolefin being organic compound burns or decompose on exposure to fire generates toxic fumes & smoke, but Flame Retardant or Fire resistant compounds help mitigate fire danger. In order for fire to occur its three basic elements (fuel, heat, and oxygen) must exist. The science of flame retardance uses chemical reactions to moderate one or more of these attributes.
A variety of flame retardant additives can be deployed in thermoplastic polymers depending on the requirements of individual end-use applications.During combustion, flame retardant additives react with the burning polymer in the vapor phase disrupting, at a molecular level, the production of free radicals and shuts down the combustion process. This mechanism is commonly used with halogenated flame retardant systems.
