An authoritative analysis of chemistry, procurement requirements, and engineering performance of Pigment Blue 29.
Synthetic Ultramarine Blue (C.I. Pigment Blue 29) is a complex sodium aluminosilicate polysulfide. Renowned for its unique, highly saturated reddish-blue undertone, it is chemically stable and non-hazardous. Unlike organic pigments, Ultramarine Blue offers exceptional thermal resistance up to 350°C and superior lightfastness, making it indispensable in high-temperature polymer processing and outdoor protective coatings.
Our manufacturing processes precisely control the particle size distribution (PSD), ensuring optimum dispersion, color strength, and minimization of low-shear agglomeration. Our OEM solutions allow industrial buyers to specify dry toner parameters, including target oil absorption values and moisture limits to prevent processing defects in delicate masterbatch formulations.
Global enterprises purchasing Ultramarine Blue face stringent regulatory demands. The primary criteria include trace element compliance (FDA Title 21 CFR for food packaging, European Standard EN71-3 for toy safety, and EU RoHS limits). Our industrial-grade and cosmetic-grade ultramarine lots are subject to strict quality control, ensuring that heavy metal contamination is kept far below regulatory thresholds.
For operations in acid-prone environments, we offer specialized silica-encapsulated acid-resistant grades. This advanced process deposits a protective nanostructured silica shell around each pigment core, preventing degradation and color loss in acidic media.
Leveraging domestic raw materials, continuous calcination technology, and optimized logistics to ensure secure, resilient pigment supply chains.
Chinese factories benefit from highly integrated supply lines for crucial precursors—kaolin clay, soda ash, sulfur, and silica. This proximity mitigates the volatility of international commodity markets and ensures uninterrupted bulk production schedules.
By transitioning from ancient batch processes to computer-controlled continuous rotary and tunnel kilns, our facilities achieve precise thermal profiling. This technology results in highly consistent color metrics (Delta E < 0.5) from batch to batch.
Strategically headquartered near major maritime hubs such as the Port of Tianjin, we streamline container consolidation and customs clearance. Our location reduces inland transport times and lowers freight costs for global distribution.

The ZDHC program is a collaborative effort by leading brands, retailers, and suppliers in the textile and footwear industry to reduce the use of hazardous chemicals. The focus of this certification is on eliminating the release of hazardous chemicals into the environment throughout the entire supply chain. Achieving ZDHC certification indicates that our company has implemented robust chemical management procedures and has met the stringent requirements for chemical handling, wastewater treatment, and pollution prevention.
The Global Organic Textile Standard (GOTS) is a certification that ensures the organic status of textiles from the harvesting of raw materials to environmentally and socially responsible manufacturing. GOTS certified products are considered to be sustainable, safe, and ethical. ZDHC focuses on the elimination of hazardous chemicals, while GOTS certification guarantees the organic and ethical aspects of the textile production.
We maintain a diverse selection of acid, direct, solvent, and sulphur dyestuffs, custom-packaged for mills and processing factories globally.

How our custom-manufactured Ultramarine products integrate into specialized industrial production lines around the world.
In high-density polyethylene (HDPE) and polypropylene (PP) molding, Ultramarine is critical for correcting the yellowish hue of virgin resins. Its high heat stability prevents degradation, maintaining color integrity throughout extrusion and blow molding cycles.
For outdoor facades, Ultramarine provides weather-resistant, non-fading properties. Formulators select our specialized grades to limit oil absorption, ensuring low viscosity even at higher pigment loading rates.
In paper mills, trace quantities of Ultramarine are introduced to neutralize yellow tones in pulp fibers, producing high-brightness printing paper. Its insolubility prevents bleeding, ensuring stable distribution throughout the paper web.
Direct answers from our research laboratory and supply chain team regarding properties, safety compliance, and custom formulation orders.
Standard Ultramarine Blue (C.I. Pigment Blue 29) is susceptible to decomposition by dilute acids, releasing trace hydrogen sulfide gas and losing its color. Acid-resistant grades feature a nanostructured silica barrier (silica encapsulation) built around the pigment crystals. This prevents acid contact and preserves chemical stability in acidic polymer formulations or harsh outdoor conditions.
We employ advanced reflectance spectrophotometers to verify color coordinate profiles ($L^*, a^*, b^*$) on every production batch. Computerized dosing systems control raw materials prior to kiln entry, keeping variance limits (Delta E) under 0.5. We also offer pre-shipment control samples for approval on large industrial orders.
Yes. Tianjin Sunrise Chem Group products comply with ZDHC Level 3 and hold GOTS certifications. Our Ultramarine lines meet European safety directive EN71-3, heavy metal limits specified by RoHS, and contain zero hazardous compounds, assuring safety in consumer and food packaging applications.
