摘要： Disclosed herein is a polyamide composition (PC) including at least one polyamide (A) and at least one carbon black (B), where the surface layer of the at least one carbon black (B) includes 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 where 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. Further disclosed herein are a process for producing the polyamide composition (PC), a process for producing a moulded article by forming the polyamide composition (PC), a moulded article including the polyamide composition (PC), and a method of using the at least one carbon black (B) in a polyamide composition (PC) for increasing the shrinkage of moulded articles made from the polyamide composition (PC).
