As an accredited Reactive Black GR factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Reactive Black GR is typically supplied in a 25 kg net weight fiber drum with inner polyethylene lining, sealed for moisture protection. |
| Shipping | Reactive Black GR is shipped in securely sealed, moisture-proof plastic drums or fiberboard containers, each lined with double-layered polyethylene bags. Containers are clearly labeled with handling precautions and hazard information. During transit, the chemical is stored in cool, dry conditions, away from direct sunlight, heat sources, and incompatible substances to ensure safety and product integrity. |
| Storage | Reactive Black GR should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and incompatible substances such as strong oxidizers and acids. Keep the container tightly sealed to prevent moisture absorption and contamination. Store at room temperature, avoiding extreme heat or cold. Ensure appropriate labeling and restrict access to authorized personnel only to maintain safety and product quality. |

Purity 98%: Reactive Black GR with 98% purity is used in cotton textile dyeing, where color uniformity and high wash fastness are achieved. Stability temperature 150°C: Reactive Black GR at 150°C stability temperature is used in high-temperature jet dyeing, where thermal degradation is minimized and dye yield is maximized. Viscosity grade low: Reactive Black GR with low viscosity grade is used in continuous dyeing processes, where rapid penetration and even color application are ensured. Particle size 12 µm: Reactive Black GR with 12 µm particle size is used in exhaust dyeing of cellulosic fibers, where smooth dispersion and sharp shade reproducibility are observed. Molecular weight 750 g/mol: Reactive Black GR with 750 g/mol molecular weight is used in printing pastes for fabrics, where clear pattern definition and low bleeding are obtained. Melting Point 185°C: Reactive Black GR with an 185°C melting point is used in thermofixation processes, where dye stability during curing leads to enhanced fastness properties. Solubility in water 60 g/L: Reactive Black GR with 60 g/L water solubility is used in pad-dyeing of viscose, where high dye liquor concentration improves depth of shade. pH stability range 4-10: Reactive Black GR stable in a pH range of 4-10 is used in multiple fiber dyeing, where compatibility across fiber types results in consistent coloration. Light fastness grade 6: Reactive Black GR with light fastness grade 6 is used in outdoor fabric applications, where prolonged color retention under sunlight is achieved. Salt tolerance 70 g/L: Reactive Black GR with 70 g/L salt tolerance is used in batch dyeing with reactive methods, where resistance to electrolyte variation ensures process reliability. |
