ABSTRACT

Inorganic flame retardants including aluminum trioxide, magnesium hydroxide, ammonium polyphosphate and red phosphorus. New efforts will obviously be directed forwards ecologically-friendly flame retardant systems. Among the new trends of flame retardancy may be noted the use of intumescent systems, polymer nanocomposites preceramic additives, additives, low-melting glasses, different types of char-formers and polymer morphology modification. Phosphorus and nitrogen compounds and systems are a small but rapidly growing group of intumescent flame retardants which are in the focus of public interest concerning environmentally friendly flame retardants. It was also found that the addition of silicone with halogenated flame retardants reduces further the heat release rate and, furthermore, improves some of the physical properties that are reduced by the addition of the halogenated flame retardants alone.
