Oil-soluble dyes, commonly known as oil colorants or solvent dyes, have become essential in a wide range of industries that require vibrant, stable, and uniform color solutions. Unlike water-soluble dyes, these formulations are specifically designed to blend seamlessly with oil-based systems, making them ideal for applications such as plastics, lubricants, candles, petroleum products, inks, and coatings. Their ability to provide high tinting strength and excellent heat resistance has significantly boosted their popularity across manufacturing sectors. Oil colorants are widely used in plastics manufacturing due to their superior performance in polymers like polystyrene, acrylics, polycarbonate, and polyethylene. These dyes disperse evenly within the material, giving finished products bright, consistent coloration without streaks or patches. Their thermal stability ensures that colors remain unchanged during high-temperature processing, a critical factor in injection mold...
