Composite materials flame-retardant intumescent

摘要

P the invention relates to the manufacture of flame-retardant materials. Composite materials, fireproofing, flexible, expansible hot formed of a component intrumescent in a granular form, of an organic binder, of an organic compound forming a product of carbonization and of fillers, the said materials, when they are heated to about 110°C, have an expansion by intrumescence up to ten times the volume of origin. / p & & p & application to the coatings of thermal insulation. / p
