| titleOfInvention | Flame retardant polyamide compositions, uses of same and processes for the preparation thereof |
| abstract | The invention relates to a composition for a thermoplastic composite material, comprising: (a) from 65 to 95% by weight of at least one reactive semi-crystalline polyamide prepolymer having an average molar mass Mn of less than 5000 g/mol and having a volume median diameter Dv50 of the reactive semi-crystalline polyamide prepolymer powder particles of 10 to 300 μm; (b) from 5 to 35% by weight of at least one flame retardant selected from an at least partially meltable flame retardant in powder form and having a volume median diameter Dv50 of 10 to 300 μm, and a non-meltable flame retardant in the form of a pre-milled powder and having a volume median diameter Dv50 of 1 to 50 μm; and (c) from 0 to 2% by weight of at least one additive, and said reactive polyamide prepolymer comprising or consisting of at least one Z/BACT/XT copolyamide wherein: - BACT is an amide unit having a molar ratio of 10 to 65%; - XT is an amide unit having a molar ratio of 30 to 60 mol%; - Z Is an amide unit unit present at a molar ratio ranging from 5 to 30%; and wherein the molar sum Z + BACT + XT is equal to 100%, the sum of the constituents (a) + (b) + (c) is equal to 100%, and said reactive semi-crystalline polyamide prepolymer has a melting point Tf < 300°C, a glass transition temperature Tg > 80°C, and a difference between the melting point and the crystallization temperature Tf -Tc < 70°C. |
