Fouad Laoutid, MateriaNova Belgium presented testing of industrial plasma technology for coating different materials with flame retardants. Such technology is today widely used in industry, for example for coating articles with metals (such as drill bits). Plasma coating equipment is today available for coating powers, films, fibres or cables. The plasma reactor technology has been tested for various materials including vegetal lignocellulose fibre insulating panels, polyamide sheets, polyester fabrics. Plasma coating of DEP (diethyl phosphate) and tri ethoxysilane, with a 5-10 µm deposit, reduced peak heat release by around one third for polyamide sheets and rendered polyester fabric difficult to ignite and self-extinguishing.
