Solvent Blue 36

Solvent Blue 36 is a synthetic organic dye commonly used as a solvent dye. It belongs to the anthraquinone dye family and is known for its excellent solubility in organic solvents. This dye is widely used for coloring hydrocarbon-based products such as oils, waxes, plastics, and fuels. It offers vibrant blue coloration with good stability and resistance to heat, light, and chemicals, making it suitable for industrial applications.

What are the core characteristics and advantages of Solvent Blue 36?

Solvent Blue 36 distinguishes itself with a balanced set of properties tailored for solvent-based systems, featuring the following key advantages:

• ‍Vivid and consistent shade: It appears as a dark blue powder with a slight violet undertone, and forms a bright, transparent blue solution when dissolved. The color consistency is controlled within 1.5 CIELAB units, ensuring uniform coloring across production batches .
• Optimized solubility profile: Practically insoluble in water (solubility ≤0.005 g/L at 25℃) but exhibits excellent solubility in medium to high polarity organic solvents, including 88 g/L in toluene, 125 g/L in ethyl acetate, and 75 g/L in mineral spirits—facilitating seamless integration into solvent-based formulations .
• Robust thermal stability: Maintains stable color and chemical structure at temperatures up to 230-250℃, making it suitable for high-temperature processing such as plastic extrusion and injection molding without discoloration .
• Superior fastness performance: Boasts light fastness of grade 6 (per ISO 105-B02), alkali resistance of grade 5 (pH 8-10), and rubbing fastness of grade 4-5, ensuring dyed products resist fading from environmental exposure and physical contact .
• Cost-effective tinting: Tinting strength reaches 100-108% relative to standard samples, requiring only 0.03-0.1% dosage relative to substrate mass to achieve target color depth, reducing material costs .
• Low environmental impact: Heavy metal content (Pb, Cd, Hg, As) totals ≤50 ppm, complying with EU REACH regulations for industrial dyes .‍

Main Applications:

Main used in coloring of polystyrene, polycarbonate, ABS,lucite,unplasticized pvc and estron.
