MACROLEX SOLVENT BLUE 97-PART II 615290

Overview

The Macrolex Solvent Blue 97, marketed commercially as Solvent Blue RR, is a high-performance solvent dye identified by Colour Index 615290. It delivers a deep, transparent blue colouration for a wide range of industrial polymers and liquid colour systems, from polystyrene and acrylic to nylon-based engineering plastics.

With CAS number 32724-62-2 and EINECS number 251-178-3, this dye is recognised worldwide under equivalent product names including Macrolex Blue RR, Keyplast Blue E, and Transparent Blue RR, making it straightforward to specify for existing colour formulations. Its molecular formula C36H38N2O2 with a molecular weight of 530.71 confirms a consistent, reproducible colouring performance in both masterbatch and liquid dosing processes.

Engineering & Design

Solvent Blue 97 belongs to the anthraquinone-based solvent dye family, which is valued for its strong tinctorial strength, thermal stability, and lightfastness in polymer applications. The dye dissolves readily in organic solvents and polymer melt systems, providing a homogeneous, transparent blue tone without the scattering effects associated with pigment dispersions.

The product is supplied in powder form and is designed for dosing into polymer compounding lines, colour masterbatch production, and solvent-based ink and coating systems. Its low migration behaviour and excellent heat resistance make it particularly suitable for injection-moulded parts, films, and fibres that must retain colour during high-temperature processing.

• Transparent coatings and lacquers
• Polymer films and fibres requiring high heat stability
• Colour matching in compounding and extrusion processes

Specifications

For colour-critical formulations, the Macrolex Solvent Blue 97 delivers batch-to-batch consistency because the dye’s defined molecular structure C36H38N2O2 provides a fixed chromophore that reproduces the same shade in every lot. Processors can therefore rely on the Macrolex Solvent Blue 97 to maintain colour targets across production campaigns, reducing the need for re-matching and rework.

Why Seven Star LLC

Seven Star LLC supplies the Macrolex Solvent Blue 97 dye with verified product documentation and batch traceability, ensuring you receive the correct colour index product for your formulation. Our team supports colourant specification for polymer processors, masterbatch producers, and ink manufacturers across the Gulf region.

As a B2B industrial supply company based in Oman, we coordinate international sourcing of specialty chemical products, providing clear documentation and responsive support for every order.

Quality & Consistency

Anthraquinone solvent dyes such as the Macrolex Solvent Blue 97 are produced under tightly controlled synthesis conditions, and each batch is analytically checked before release. The documented Colour Index 615290 and CAS registration ensure that the product you receive is exactly the material specified for your formulation, simplifying incoming inspection and regulatory filing.

Because the dye is fully soluble in the polymer or solvent system, colour development is even and transparent, free of the haze that can appear with insoluble pigments. This makes the Macrolex Solvent Blue 97 particularly valuable for transparent containers, packaging film, and decorative articles where depth of colour and clarity are equally important.

Documentation & Supply

Seven Star LLC provides the Macrolex Solvent Blue 97 with technical documentation covering product identification, handling, and storage guidance, and our team can support the preparation of material specifications for your procurement system.

For ongoing production requirements, we coordinate scheduled supply to keep your masterbatch or ink line running without interruption, with batch documentation retained for traceability.
