Abstract
The present invention relates to high-voltage components, especially for electromobility, comprising polymer compositions based on at least one polyester and 10,10′-oxybis-12H-phthaloperin-12-one, and to the use of 10,10′-oxybis-12H-phthaloperin-12-one for production of polyester-based products, with the proviso of a color difference ΔE<20 from the L*a*b* coordinates of a color number beginning with “2” in the RAL color chart, and to the use of 10,10′-oxybis-12H-phthaloperin-12-one for marking of polyester-based products as high-voltage components.
Claims16
An electromobility assembly comprising:
- a voltage conducting part having an operating voltage according to class B of ISO6469-2:2018, and
- a high-voltage component in direct contact with or directly adjacent to the voltage-conducing part, wherein the high-voltage component comprises a polymer composition comprising:
- (A) at least one polyester, 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 polyester 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).
