Solvent Yellow 93

Advanced plastic colorants are the most ideal colorants for various plastics, offering advantages such as strong coloring power, excellent heat resistance, high lightfastness, resistance to acids and alkalis, and vibrant colors. They are widely used in the coloring of daily-use plastics, bobbin materials, industrial greases, paints, inks, and masterbatches. Some varieties are suitable for coloring and spinning of chemical fibers, polyester, nylon, and acetate fibers.

Application Range

Advanced plastic colorants fall under the category of oil-soluble dyes and can dissolve in organic solvents. They can be used individually or blended in specific proportions to achieve various color tones as needed.

Dye Application

When these dyes are dissolved in a plastic melt, they distribute in a molecular state. For coloring various plastics, a specific proportion can be directly added to the plastic and uniformly mixed before pre-molding or molding. The color intensity can be adjusted according to requirements. In transparent and clean resins, the dyes produce bright and transparent color tones. When used in combination with an appropriate amount of titanium white powder and other dyes, semi-transparent or opaque color tones can be achieved. The dosage can be negotiated based on needs, with typical usage being 0.02%-0.05% for transparent tones and around 0.1% for opaque tones.
