Abstract: The use of at least one MXDZ polyamide, obtained from the polycondensation of meta-xylylenediamine (MXD), with a C6 to C18 aliphatic (Z) dicarboxylic acid, in particular C6 to C12, in a mixture including at least one aliphatic polyamide A obtained from the polycondensation of a unit selected from: a C6 to C12 lactam, a C6 to C12amino acid, and an XY unit obtained from the polycondensation of a C4 to C18, aliphatic diamine (X), especially C4 to C12, and a C6 to C18 aliphatic dicarboxylic acid (Y), especially C6 to C12, circular-section glass fibres and optionally at least one impact modifier and/or at least one additive, said at least one MXDZ polyamide and said mixture constituting a composition, and the MXDZ/A weight ratio being from 0.11 to 0.83, in particular from 0.11 to 0.66, to limit the warping of said composition during processing, in particular by injection or compression moulding.

IPC: C08L77/06
Abstract: The field of molded articles and fiber-reinforced thermoplastic compositions for obtaining them. The use of the reinforced thermoplastic composition for obtaining a thin molded article with reduced warpage. The composition may include: from 30 to 70% by weight of an amorphous polyamide matrix by total weight of the composition; from 30 to 70% by weight of glass fibers with a circular cross-section by total weight of the composition; and optionally additives.

Abstract: The use of circular-section glass fibres in a mixture including at least one MXDZ polyamide, obtained from polycondensation of meta-xylylenediamine (MXD), with a C6 to C18 aliphatic (Z) dicarboxylic acid, and at least one aliphatic polyamide A obtained from the polycondensation of a unit selected from: a C6 to C12 lactam, a C6 to C12 amino acid, and an XY unit obtained from the polycondensation of a C4 to C18 aliphatic diamine (X), and a C6 to C18 aliphatic dicarboxylic acid (Y), circular-section glass fibres and optionally at least one impact modifier and/or at least one additive, said circular-section glass fibres and said mixture constituting a composition, said circular-section glass fibres being present from 30 to 75% by weight and with respect to the total weight of the composition, to improve the mechanical properties of said composition, including elongation at break, after processing, in particular by injection or compression moulding.
