Abstract:
1. A polymer composition comprising: at least 20 weight %, based on the total weight of the polymer composition, of at least one polycondensation polymer having a heat deflection temperature of above 80° C. under a load of 1.82 MPa when measured according to ASTM D648; from 0 to 5 weight %, based on the total weight of the polymer composition, of at least one polymer having a heat deflection temperature of at most 80° C. under a load of 1.82 MPa when measured according to ASTM D648; a white pigment present in a concentration of at least 4 weight %, based on the total weight of the composition; a black pigment present in a concentration of at least 0.0001 weight % up to 0.005 weight %, based on the total weight of the composition, wherein the polycondensation polymer is selected from the group consisting of at least partially aromatic polyamides, polyamideimides, liquid crystalline polymers, polyimides, polyetherimides, polyaryletherketones, polyarylethersulfones and polyphenylene sulfides.
