Abstract: The present invention relates to a polyamide composition (PC) comprising at least one polyamide (A) and at least one carbon black (B), wherein the surface layer of the at least one carbon black (B) comprises not more than 2 % by weight of oxygen, based on the total weight of the surface layer of the at least one carbon black (B), and wherein the weight of oxygen in the surface layer is measured by X-ray photoelectron spectroscopy at an X-ray penetration depth of 2 to 10 nm. The present invention further relates to a process for producing the polyamide composition (PC) and to a process for the production of a moulded article by forming the polyamide composition (PC). In addition, the present invention relates to a moulded article comprising the polyamide composition (PC), and to the use of the at least one carbon black (B) in a polyamide composition (PC) for increasing the shrinkage of moulded articles made from said polyamide composition (PC).
