Abstract (en)
[origin: WO2022106776A1] The present invention relates to a transparent moulding composition comprising, by weight (the total being equal to 100%): (A) 35 to 84% polyamide mixture comprising 10 to 95% of at least one semi-crystalline aliphatic polyamide having an average number of carbon atoms relative to the nitrogen atom greater than or equal to 8, and 90 to 5% of at least one amorphous polyamide; (B) more than 10 to 30%, in particular 15 to 30%, of at least one impact modifier; (C) 6 to 20% of short glass fibres; (D) 0 to 10% of at least one prepolymer; (E) 0 to 5%, in particular 0.1 to 5%, of at least one additive chosen from stabilisers, colourants, plasticisers, processing aids or a mixture thereof, the refractive index of each constituent (A), (B), (C) and (D) being between 1,500 and 1,540, the composition being free of PEBA and having a dry modulus measured at 23°C of greater than 1,700 MPa.
