Minerals on fire. Flame retardants look to mineral solutions
This paper examined the leading mineral flame retardant (mineral FR) products, their properties and most importantly their specific market applications based on technical and economic factors. Whereas the halogenated flame retardants are more and more under pressure because of their significant disadvantages related to the formation of smoke and toxic, corrosive decomposition products, the volume of mineral flame retardants grows at an annual rate of 3 & to 6 %, depending on area and source, because they provide extremely low smoke values, they absorb toxic and corrosive gases, and generate nothing but water, CO2 and harmless metal oxides. Wherever technical solutions are developed that allow the use of mineral FRs these formulations are nowadays preferred. The different mineral FRs used were examined. Their properties such as physical density, temperature stability, endothermic enthalpies, flame performance were investigated. The most common mineral FRs are aluminum hydroxide, magnesium hydroxide and huntite/hydromagnesite. Their consumption in USA and Western Europe was shown as well as the market development of the mineral FRs in Western Europe from 1998 to 2002. Within the group of the FRs the aluminum hydroxide will grow slower than Mg based products. The highest growth rate is expected from the newer product groups like brucite and huntite/hydromagnesite because of their lower cost level. A market share of some 10 % to 15 % per annum is the target for the mineral flame retardant supply industry.
