Abstract: The invention relates to a thermoplastic composition comprising (A) a semi-aromatic copolyamide comprising repeat units derived from diamine consisting primarily of tetramethylene diamine and hexamethylene diamine, or pentamethylene diamine and hexamethylene diamine, and dicarboxylic acid consisting primarily of terephthalic acid, having a VN of at least 100 ml/g; and (B) a reinforcing agent. The invention also relates to a plastic part made of the thermoplastic composition. The invention further relates to an automotive vehicle comprising a structural part made of the thermoplastic composition and to an electrical assembly comprising a plastic component made of the thermoplastic composition.

Abstract: The invention relates to a polyamide composition with an increased resistance against blistering that is for example the result of a reflow soldering process. The composition comprises: A) 99-50 wt % of at least one polyamide A derived from: A1) at least one di-amine monomer having 4 carbon atoms and wherein the amount of C4-diamine is at least 2 mol % relative to the total amount of di-amine and, A2) at least one di-acid monomer, wherein at least one of the monomers has at least one aromatic structural unit, and wherein the polyamide A, has a molecular weight, expressed as Mn, of at least 9000 g/mol, and B) 1-50 wt % of at least one reinforcing agent and C) 0-20 wt % of inorganic fillers and/or additives, D) 0-49 wt % of one or more polymers other than A) wherein the sum of A, B, C and D amounts to 100 wt %. The invention also relates to the use of the polyamide composition and to a shaped article made out of the polyamide composition.
