Ultramarine blue pigment is one of the most heat-stable organic pigments available, making it an ideal choice for plastics processing where temperatures can exceed 300°C. Its ability to withstand the extreme heat of extrusion and injection molding without color shift is a key advantage.
In polyolefins such as polyethylene (PE) and polypropylene (PP), ultramarine blue provides excellent color strength. It does not migrate or bleed, ensuring long-term color stability in finished plastic products.
Shree Krishna Ultramarine Pigments (P) Limited supplies specialized ultramarine blue grades formulated for plastics, including grades designed for PVC, EVA, masterbatches, and universal plastic applications. These grades offer controlled particle size and easy dispersion in polymer matrices.
Ultramarine blue is also FDA-compliant for use in food-contact plastics under specific regulations, making it suitable for packaging applications where safety is paramount.
Plastic manufacturers who switch to high-quality ultramarine blue from premium suppliers report fewer batch rejections, more consistent color across production runs, and improved customer satisfaction.
