Abstract (en)
[origin: WO2022129765A1] The present invention relates to a moulding composition comprising by weight: (A) 38 to 87% of at least one semi-crystalline aliphatic polyamide, (B) 3 to 25% of a hollow glass reinforcement, (C) 5% to 30% glass fibres, (D) 5 to 15% of at least one impact modifier chosen from a polyolefin, a polyether block amide (PEBA-1) and a mixture thereof, the polyolefin and the PEBA-1 having a flexural modulus less than 200 MPa, in particular less than 100 MPa, as measured according to standard ISO 178: 2010, at 23°C, (E) 0 to 2% by weight of at least one additive, the sum of the proportions of each constituent of the composition being equal to 100%, the density of the composition being less than 1.12 g/cm3.
