Flame Retardant Materials from Oxidative Polymerization of Naturally Derived Cashew Nut Shell Liquid (CNSL) Derivatives

摘要

Flame retardant (FR) materials control or reduce the risk of fire and therefore have a direct impact on safety. Every year approximately, 909,000 ton of flame retardant additives are used to make various commercial polymers less flammable1. Most of the FRs used currently are based on halogens and phosphates. Halogenated FR’s are, also very persistent in the environment and non- biodegradable. They are toxic to human and animal life. The European Union has already banned the use of Halogenated Flame Retardants. The toxic and persistent nature of the halogenated FR’s has resulted in the immediate need for developing non-toxic and non-halogenated FRs.
