Solvent Blue 104
Solvent Blue 104, sold under the trade name Transparent Blue 2B, is a high strength anthraquinone oil soluble solvent dye that delivers a clean medium blue shade in transparent plastics. With heat resistance up to 300°C and good to excellent light and weather fastness, it is a widely used engineering plastics dye for PET, PC, PA, PS, ABS and PMMA, and is a proven choice for spin dyeing of nylon fibers. Its high tinting power keeps dosing low, which helps control formulation cost in masterbatch and compounding applications.
Solvent Blue 35
Solvent Blue 35, marketed as Transparent Blue 2N, is an economical anthraquinone solvent dye producing a bright greenish blue in polystyrene and ABS. It offers high color strength and excellent heat resistance for its class, with a melting point of 127°C. Light fastness is good to excellent in full shade but decreases as titanium dioxide is added, so it is best positioned for transparent or lightly tinted articles. As a cost effective oil soluble dye, it is a common choice for general purpose PS and ABS coloring.
Solvent Blue 45
Solvent Blue RS (Solvent Blue 45) is a reddish blue anthraquinone dye with a melting point of 200°C, giving good heat resistance alongside good light fastness. This oil soluble solvent dye is used across engineering plastics and is highly recommended for spin dyeing and PET blowing where a stable reddish blue is needed. It dissolves excellently in organic solvents, which also makes it suitable for solvent based coloring of coatings, inks and foils. A dependable mid-range grade for transparent blue shades.
Solvent Blue 67
Bright Blue GN (Solvent Blue 67) is a phthalocyanine based solvent dye giving a standard greenish blue shade with acceptable light fastness. Unlike anthraquinone transparent dyes, it is mainly used for spin dyeing of clothing fibers and indoor decoration goods, where its shade and cost profile fit high volume textile coloring. It shows good heat stability up to 260°C and high color strength, and can also be used in plastics where a strong turquoise leaning blue is required.
