Inorganic flame retardant developments
Sophie Duquesne, ENSCL (Ecole Nationale Supérieure de Chimie de Lille), presented applied research projects into PIN flame retardant applications. Development and testing of a lightweight carpet for aviation showed the complexity of smoke density and smoke toxicity, depending on the different elements of the carpet (pile, weft, warp, backing, backcoating) and on whether these are tested separately or together.
In another project, phosphorus, silicon and nitrogen based compounds and sodium hydroxide were used to treat flax-PLA (polylactic acid) composites. In a third project, a silicone surface plasma treatment was tested to improve performance of high temperature resistant textiles.
