Abstract
Relates to the use of a thermoplastic polymer molding compound for producing metallically coated light-reflecting components based on thermoplastics, which are suitable for operating temperatures of at least 200° C. The polymer molding compound used according to the present invention is characterized in that it comprises polyamides which are selected from a group which comprises homopolyamides, copolyamides, and mixtures (blends) made of homopolyamides and copolyamides and mixtures made of homopolyamides or copolyamides, these polyamides being selected from a group which comprises amorphous and transparent polyamides, and these polyamides having a glass transition temperature (Tg) of at least 205° C. Light-reflecting components produced according to the use according to the present invention are suitable for operating temperatures of at least 200° C. and comprise reflectors for traveling lights of vehicles, for signal and lighting devices, and reflectors for solar collectors.
