Explore our premium grade chemical colorants and direct dyes customized for global paper, textile, and plastic manufacturers.
In the highly technical domain of industrial colorants, Oil Blue AP (widely recognized as Solvent Blue 36) represents a critical anthraquinone dye valued for its exceptional thermal stability and bright color performance. Used across plastics, fuel lubricants, masterbatches, and engineering resins, securing a reliable, cost-effective, and ecologically compliant supplier is vital to maintain downstream product integrity.
As regulatory frameworks like REACH, TSCA, and RoHS grow more stringent, global purchasers are increasingly seeking manufacturers who balance economic pricing ("Discount") with strict quality control certifications. Tianjin Sunrise Chem Group has spent decades refining the synthesis of anthraquinone dyes to meet these rigorous specifications while maintaining price leadership.
Whether you require high-temperature tolerance for injection molding or clean solubility profiles for petroleum identification marker inks, choosing a manufacturer with verified production capacities ensures operational efficiency and consistent product output.
Providing global clients with certified chemical colorants, exceptional reliability, and custom-tailored solutions.
Solvent Blue 36, chemically cataloged as 1,4-bis(isopropylamino)anthraquinone, is a synthetic anthraquinone-based dye. The structure possesses symmetrical alkylamino chains that impart superior solubility in non-polar organic solvents and plastic matrices. Unlike azo-based dyes, which can thermally degrade or break down into aromatic amines under extreme conditions, the anthraquinone core of Oil Blue AP offers exceptional molecular resilience.

In thermal processing environments, minor deviations in dye purity can lead to polymer degradation, gas bubble formation, or discoloration. Tianjin Sunrise Chem Group guarantees a high purity level (>98.5%) for our Oil Blue AP, ensuring that trace residues of inorganic salts and unreacted intermediates are kept to an absolute minimum. This level of control is crucial for high-speed fiber spinning and thin-wall plastic injection molding applications.
Leveraging scale, advanced synthesis technologies, and structural supply chain integration to provide global buyers with high-quality and cost-competitive solutions.
Our strategic factory location in the chemical manufacturing corridor of Tianjin ensures a direct pipeline of key intermediates (such as 1,4-dihydroxyanthraquinone). This helps us avoid market volatility and offer stable "Discount" pricing structures.
By using automated, closed-loop synthesizers, we significantly reduce manufacturing energy footprints and labor costs. We pass these savings directly to partners through bulk-purchase discounts without sacrificing dye performance.
Our quality assurance labs inspect every outbound shipment. Using HPLC-MS, UV-Vis spectrophotometry, and thermal analysis equipment, we ensure each batch of Oil Blue AP matches standard spectrophotometric curves and solubility margins.
Cooperating with textile and paper mills for many years shows that the factory has established a strong and reliable business relationship. This kind of long-term collaboration can bring numerous benefits, such as consistent orders, shared resources, and mutual support. It also indicates that the factory has a good track record of delivering quality products and meeting the needs of its partners.
Our mission is to drive business growth by providing reliable and customized products. Our goal is to make a significant contribution to our customers' success by consistently delivering first-class products and exceptional customer service. By building lasting partnerships, we strive to be a catalyst for our clients' success.

How global industries apply Solvent Blue 36 (Oil Blue AP) in localized and macro-scale manufacturing setups.
In injection molding of ABS, Polycarbonate (PC), and Polystyrene (PS), colorants must endure heat up to 280°C without shade shifting. Oil Blue AP maintains thermal integrity, ensuring automotive components and consumer electronics housing retain color stability without fading.
Oil Blue AP is highly soluble in aliphatic and aromatic hydrocarbons. Fuel companies use it to color-code lubricants, transmission fluids, and heating oils for tax status demarcation and grade differentiation, ensuring clear, precipitate-free coloring.
Used in formulation of ballpoint pen inks (working alongside Solvent Red 25 and Nigrosine Black), permanent marking pen fluids, and digital printing inks. The dye's molecular design ensures zero clogging in micro-pores, maintaining consistent fluid dynamics.
With years of experience, we have successfully established strong partnerships in many countries. Our dedication to meeting global demands and exceeding customer expectations has earned us a reputation as a reliable supplier worldwide.
Environmental protection is the cornerstone of our innovation. We dedicate ourselves to providing clients with eco-friendly, high-quality colorants that balance productivity with environmental harmony, driving the industry towards a more sustainable development path while delivering high-performance products—for a greener textile industry and a sustainable future.
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 Level 3 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. The GOTS certification guarantees that the textiles are made from organic fibers, that chemical inputs are minimized, and that strict environmental and labor standards are met throughout the production process. GOTS certified products are considered to be sustainable, safe, and ethical.
Addressing supply chain volatility, compliance audits, and batch uniformity for multinational enterprises.
Navigating global regulatory landscapes requires clean chemical profiles. We provide complete chemical declarations, heavy-metal profiling, and RoHS/REACH compliance paperwork to prevent customs hold-ups and simplify compliance audits.
