Physical And Chemical Properties
- pH Value: 6-7
- Light Fastness: 8
- Heat Resistance: 300℃
- Color Strength: 100±5%
- Moisture Content: ≤ 0.5%
- Water Soluble Salts: < 0.5%
These physical and chemical properties lay a solid foundation for its stable performance in high-temperature processing, outdoor applications, and high-demand industrial coatings.
1. Superior Light Fastness: Grade 8 rating ensures exceptional color retention, resisting fading even under prolonged intense sunlight—critical for outdoor-facing products like plastic components, PA materials, and fiber-based goods.
2. Outstanding Heat Resistance: Withstands temperatures up to 300℃ without color degradation, perfectly adapted to high-temperature processing such as plastic molding, PA processing, and fiber drawing.
3. High Color Strength: 100±5% color intensity guarantees vivid, uniform fuchsia hues with minimal dosage, reducing material costs while maintaining consistent coloring effects across substrates.
4. Low Moisture & Water-Soluble Salts: ≤0.5% moisture and <0.5% water-soluble salts ensure excellent dispersion in matrices (e.g., plastic resins, PA substrates, fiber materials) and prevent agglomeration, optimizing production efficiency and product quality.
5. Neutral pH & Odorless: pH value of 6-7 minimizes corrosion risk to production equipment, while the odorless formula ensures a safe and environmentally friendly working environment during processing.
2. PA (Polyamide) Materials: Specifically suitable for PA-based products (e.g., engineering plastics, automotive parts, electronic components), adapting to PA's processing temperature requirements and ensuring color uniformity.
3. Fibers Sector: Applicable for coloring synthetic fibers (e.g., polyester, polyamide fibers) during drawing processes, delivering fade-resistant hues that preserve fiber strength and texture.
4. Photovoltaic Auxiliary Applications: Compatible with photovoltaic system auxiliary materials (e.g., protective coatings for components, insulation materials) requiring stable coloring, leveraging its excellent light fastness and environmental resistance.
1. Consistent Purity: Each batch undergoes rigorous testing for pH value, moisture content, color strength, light fastness, heat resistance, and dispersion performance, ensuring compliance with international industrial standards.
2. Reliable Supply Chain: We maintain stable raw material sources and advanced production facilities, eliminating batch-to-batch variations and supporting your continuous production schedule.
3. Professional Technical Support: Our team of chemical experts provides customized solutions for pigment dispersion optimization, processing parameter adjustment, and troubleshooting, helping you maximize product performance in plastics, PA, and fiber applications.
1. Compliance with Regulations: Conforms to AP (89) 1, EN 71 Part 3:1994, and IEC 62321 standards, ensuring safety for industrial applications and global market distribution.
2. Low Environmental Impact: The neutral pH and low water-soluble salts minimize environmental pressure during wastewater treatment when used in compliant production processes.
3. Safe Processing Traits: Odorless, non-toxic, and stable under normal storage and processing conditions, ensuring occupational health and safety for operators.
