<p>Flame-resistant thermoplastic compositions based on polyamide comprising a mixture of polyamide(s), of Sb2O3 and/or of melamine cyanurate and of Mg(OH)2. They may contain glass fibres, inorganic fillers and/or additives such as colorant(s), lubricant(s), stabilisers against heat or light, impact strength improvers, plasticisers and antioxidants. They are prepared by mixing constituents in powdered form, introducing the mixture with the polyamide into an extruder and incorporating glass fibres into the molten material. These compositions are employed especially for the production of moulded or extruded objects, of films or of composite materials exhibiting an excellent fire resistance (V0 under 1.6 mm) and good mechanical characteristics.</p> |
