<p>The invention relates to thermoplastic molding materials comprising (A) from 34 to 99.99% by weight of at least one thermoplastic polymer selected from (i) polyarylene ethers, (ii) polyetherimides, (iii) polyarylene sulfides and (iv) polycarbonates having a glass transition temperature of at least 145°C, and to copolymers of the aforementioned polymers (i) to (iv), (B) from 0.01 to 10% by weight of at least one organic black pigment which is transparent in the range from 1000 nm to 1600 nm and has a thermal stability under DIN EN 12877-1 of at least 300°C, (C) from 0 to 6% by weight of at least one demolding agent selected from fatty acids, esters and amides, (D) from 0 to 50% by weight of one or more additives, where the sum of the percentages by weight of (A), (B), (C) and (D) adds up to 100% by weight. The invention further relates to a process for preparing the thermoplastic molding materials and to the moldings obtainable therefrom. The invention finally relates to the use of the thermoplastic molding materials for reducing the accumulation of heat in plastic components, moldings, films or membranes.</p> |
