Abstract: A composition including from: a) 35% to 100% by weight of at least one semicrystalline aliphatic polyamide and/or one polyamide of formula MXDZ wherein MXD is meta-xylylenediamine and Z is a C6 to C12 aliphatic dicarboxylic acid, the semicrystalline aliphatic polyamide and/or the polyamide of formula MXDZ having a total acidity between from 70 to 180 μeq/g and a total basicity of less than 100 μeq/g; b) 0 to 25% by weight of polyolefins; c) 0 to 60% by weight, of glass fibers; d) 0 to 2% by weight of at least one additive; e) 0 to 30% by weight of at least one flame retardant; the sum a)+b)+c)+d)+e) being equal to 100%, the semicrystalline aliphatic polyamide and/or the polyamide of formula MXDZ having a melt flow index (MFI) between from 4 to 50 g/10 min.
