Related Information

Pigment yellow 191 is similar to CI Pigment Yellow 83, with low color strength, but excellent heat resistance. In high-density polyethylene (HDPE, 1/3 standard depth), the heat resistance is 300 ° C, without dimensional deformation, and has good Light fastness (grade 7-8); excellent migration resistance in plastic PVC; temperature resistance up to 330 ℃ in polycarbonate, and resistance to organic solvents. It is mainly used in the United States for coloring traffic coatings.
