Abstract
The present invention relates to high-voltage components, in particular for electromobility, containing polymer compositions based on at least one polyamide and 10,10′-oxybis-12H-phthaloperin-12-one, and to the use of 10,10′-oxybis-12H-phthaloperin-12-one for marking polyamide-based articles of manufacture as high-voltage components.
Claims19
An electromobility assembly comprising:
- a voltage-conducting part having an operating voltage according to class B of ISO6469-3:2018;
- and
- a high-voltage component in direct contact with or directly adjacent to the voltage-conducting part, wherein the high-voltage component comprises a polymer composition comprised of the following components:
- (A) at least one polyamide, and
- (B) a 10,10′-oxybis-12H-phthaloperin-12-one dye, wherein
- the 10,10′-oxybis-12H-phthaloperin-12-one dye component (B) is present in an amount of 0.01 to 5 parts by mass per 100 parts by mass of the at least one polyamide component (A) which is sufficient to achieve (i) an orange color corresponding to a color distance ΔE<20 from the L*a*b* coordinates of a color number beginning with “2” in the RAL color chart, and (ii) reduced contact bleeding of the 10,10′-oxybis-12H-phthaloperin-12-one component (B) as compared to a high-voltage component having 12H-phthaloperin-12-one as component (B).
