Claims13
A UV laser-markable dark-colored insulation material that can produce a light-color marking with a high initial contrast of at least about 55% as measured according to AS4373 standards, wherein the insulation material comprises:
- (i) fluoropolymer up to 100 parts;
- (ii) color pigment configured to render the insulation material dark-colored in an amount ranging from 1 to 20 phr based on the fluoropolymer;
- and
- (iii) UV laser-marking additive configured to produce the light-color marking on the dark-colored insulation material in an amount ranging from 1 to 20 phr based on the fluoropolymer wherein the UV laser-marking additive comprises a mixture of mica, titanium dioxide, silicon dioxide, and antimony-doped tin oxide or mica coated with titanium dioxide, silicon dioxide, and antimony-doped tin oxide.
