Explore our premium selection of industrial dyestuffs and chemical colorants formulated for rigorous performance standards.
In high-precision polymer fabrication and industrial chemical synthesis, Solvent Blue 35 (CAS Registry No. 17354-14-2) represents a cornerstone anthraquinone-derived dyestuff. Recognized molecularly as 1,4-bis(butylamino)anthraquinone, Solvent Blue 35 offers unparalleled thermodynamic stability and spectroscopic purity. Compared to simple monoazo or disazo structures, the anthraquinone core delivers a robust resonance hybrid layout that successfully absorbs photons within the orange-red spectral region (wavelengths of maximum absorption at ~600 nm to 645 nm), reflecting a deep, vibrant cerulean blue.
When procurement executives audit OEM Solvent Blue 35 factories, analyzing physical-chemical thresholds is vital to ensuring line stability and minimizing structural defects in extruded plastics. The presence of butyl side chains enhances solubility matrices across non-polar matrices, making it highly compatible with polymers without inducing stress cracking or microscopic phase separation.
For specialized applications such as masterbatch production, automotive plastics, and ink formulation, understanding the precise limits of the chemical structure is necessary. Below is the analytical data profile that defines high-quality Solvent Blue 35 manufacturing standards:
| Technical Property | Standard Rating / Measurement |
|---|---|
| Chemical Formula | C22H26N2O2 |
| Molecular Weight | 350.45 g/mol |
| Heat Resistance | 280°C – 300°C (Max limit) |
| Lightfastness (Blue Wool Scale) | 7 – 8 (Excellent) |
| Solubility in Xylene (20°C) | ≥ 50 g/L |
| Acid/Alkali Resistance | Grade 5 (No visible migration) |
Solvent Blue 35 is not just an additive; it is a critical component across diverse modern manufacturing sectors globally. From micro-molded medical components in Europe to raw fuel marking markers in North America, this dye fulfills critical functional requirements:
Widely utilized in the coloring of Polystyrene (PS), Polymethyl Methacrylate (PMMA), Polycarbonate (PC), and Polyethylene Terephthalate (PET). Its thermal stability ensures that under high-temperature extrusion and injection molding (reaching 280°C), the dye molecules do not degrade, preventing shifts in color or polymer degradation.
In global fuel distribution, government regulations mandate colored markers to differentiate tax-free agricultural fuels, heating oils, and marine fuels. Solvent Blue 35 is chosen for its oil solubility and low ash content, ensuring zero particulate deposition in internal combustion engines.
From ballpoint pen inks to specialized flexographic packaging inks, Solvent Blue 35 provides strong tinting strength and compatibility with diverse resin binders, ensuring consistent film formation and long-lasting UV resistance on metal foils and plastics.
As manufacturing paradigms shift towards sustainability and automation, Chinese chemical factories have transitioned from traditional batch production to intelligent manufacturing ecosystems. This evolution addresses two major issues for international buyers: supply chain continuity and batch consistency.
By integrating distributed control systems (DCS) and automated feeding mechanisms, raw material addition, reaction temperatures, and filtration parameters are tightly monitored. This prevents the generation of unwanted side-reaction isomers, resulting in high dye yield and standard shade consistency.
Additionally, close proximity to major deep-water ports (such as Tianjin Port) allows for direct, climate-controlled container logistics, protecting shipment containers from excessive humidity and temperature changes that could cause dye caking or packaging degradation during transit.
Tianjin Sunrise Chem Group specializes in manufacturing high-quality dyestuffs. Including Direct dyes, Acid dyes, Basic dyes, Sulphur dyes, Solvent dyes, Liquid dyes and Fluorescent dyes.
