Abstract

Thermoplastic moulding compositions containing PA1 A. a thermoplastic polymer and PA1 B. 0.1 to 50% by weight, with respect to A, of an inorganic substance with an average particle diameter of 0.1 to 100 nm, PA1 and the use of superfine inorganic substances as defined by B for increasing the X-ray contrast of thermoplastic moulding compositions comprising A and B.
