These Physical And Chemical properties ensure excellent dispersion, color retention, and adaptability to high-temperature processing in target industries.
1. Superior Light Fastness: Grade 8 rating provides exceptional color retention, outperforming standard pigments in resisting fading under intense sunlight or long-term use—critical for outdoor plastic products and fiber materials.
2. Outstanding Heat Stability: Withstands temperatures up to 300℃ without color degradation, perfectly suited for high-temperature plastic molding, masterbatch processing, and fiber drawing processes.
3. High Color Strength: 100±5% color intensity guarantees vivid, uniform brilliant red hues with minimal dosage, reducing material costs while maintaining consistent coloring effects.
4. Low Moisture Content: ≤0.5% moisture ensures good dispersion in plastic resins and masterbatch matrices, preventing agglomeration and optimizing production efficiency.
5. Optimized Oil Absorption: Oil absorption value of 45 enhances compatibility with various binders and substrates, further improving dispersion performance and color uniformity.
6. Neutral pH & Odorless: pH value of 5-6 reduces corrosion risk to processing equipment, while the odorless formula ensures a safe and environmentally friendly working environment.
2. Masterbatch Production: Ideal for color masterbatch formulation, providing stable coloring performance that remains consistent during masterbatch storage and subsequent processing.
3. Fiber Drawing Industry: Applicable for coloring synthetic fibers (e.g., polyester, polyamide fibers) during the drawing process, delivering bright, fade-resistant red hues that maintain fiber strength and texture.
Related Industrial Fields: Extensible to other high-temperature processing scenarios requiring durable, vivid coloring, aligning with the needs of precision manufacturing.
1. Consistent Purity: Each batch undergoes rigorous testing for pH value, moisture content, color strength, heat stability, and dispersion performance, ensuring compliance with international industrial standards.
2. Reliable Supply Chain: We maintain stable raw material sources and advanced production facilities to avoid batch-to-batch variations, supporting your continuous production schedule.
3. Technical Support: Our professional team provides customized solutions for pigment dispersion optimization, processing parameter adjustment, and troubleshooting, helping you maximize product performance.
1. Compliance with Regulations: Conforms to USA FDA, EU SVHC, RoHS, AP (89) 1, ELV Directive 2000/53/CE, EN 71:2013, and other regional chemical safety standards, suitable for global market distribution.
2. Low Environmental Impact: The neutral pH (5-6) and low moisture content minimize environmental pressure during wastewater treatment (when used in compliant processes).
3. Hazard-Free Traits: Odorless formula and non-toxic properties ensure worker safety during handling and processing, aligning with occupational health standards.
