Product Description Product Description Physical PropertiesAppearance and Character: Dark red to dark crimson crystalline powder at room temperature, with no obvious odor; some industrial-grade products may have a slight reddish-brown tint due to impurities.Melting Point: 158~162oC (literature value; actual measurement may fluctuate slightly depending on purity). It melts easily when heated without decomposition, but may oxidize slowly when the temperature exceeds 200oC.Solubility: Typical "oil-soluble but water-insoluble" property -Easily soluble in non-polar/weakly polar solvents: such as toluene, xylene, ethyl acetate, acetone, cyclohexanone, mineral oil, vegetable oil, etc., forming a bright red transparent solution after dissolution;Slightly soluble in polar alcohols like ethanol and isopropanol (solubility: approximately 0.5~2 g/100mL at 25oC);Insoluble in strongly polar solvents such as water, ethylene glycol, and glycerol, and also insoluble in dilute acid and dilute alkali solutions.Density and Particle Size:Relative Density (25oC): 1.12~1.18 g/cm3;Average Particle Size (industrial grade): 10~50 μm (can be refined to 1~5 μm through grinding to improve dissolution and dispersion efficiency).Oil Absorption: As it is a solvent dye (not a pigment), there is no mandatory standard for oil absorption, and it is usually not tested (for pigments, oil absorption is used to judge dispersibility, while "solubility" is the core indicator for solvent dyes).III. Chemical PropertiesStability:Stable under normal temperature and pressure; shelf life can reach 2~3 years when stored in a dark and sealed condition;Light Fastness: Moderate (rated Grade 4~5 according to ISO 105-B02 standard). It is not easy to fade under indoor light, but may undergo slight discoloration when exposed to strong ultraviolet rays (e.g., outdoor exposure) for a long time;Heat Resistance: Short-term heat resistance up to 180~200oC (no obvious decomposition within 10 minutes); the recommended temperature for long-term use should not exceed 150oC (high temperature may cause oxidation of the dye and darkening of the solution color);Chemical Resistance: Stable in neutral and weakly acidic media (no reaction within the pH range of 3~8). However, under strongly acidic (pH<2) or strongly alkaline (pH>12) conditions, the azo bond may break, leading to fading or precipitation.Coloring Characteristics: It presents a "bright red" color after dissolution, with no fluorescence and high color saturation. It can maintain its vividness even after dilution (e.g., when diluted to a 0.1% concentration in mineral oil, it still shows a clear red color).IV. Application FieldsAs a solvent dye, its core advantage is "compatibility with non-aqueous substrates and uniform coloring". The main application scenarios include: Coloring of Plastics and Rubbers: Used for coloring thermoplastics such as polyethylene (PE), polypropylene (PP), polystyrene (PS), and ABS resin, as well as elastomers such as nitrile rubber and silicone rubber (the melting temperature needs to match that of the plastic/rubber substrate);Coloring of Oils and Lubricants: Used for marking and coloring diesel oil, gasoline, lubricating oil, hydraulic oil, etc. (e.g., distinguishing different types of oils), and coloring does not affect the physical and chemical properties of the oils;Coatings and Inks: Used for red coloring of alkyd resin coatings, nitrocellulose lacquers, and gravure printing inks (non-aqueous systems). It has good compatibility with resins and is less prone to floating or blooming;Other Fields: Used for coloring candles, crayons, solvent-based leather finishes, and cosmetics (e.g., oil-based eye shadows and lip glosses, which must meet cosmetic-grade standards).V. Other Key PropertiesProduct Grade: The mainstream grade is industrial grade (for plastics, oils, and coatings); a few manufacturers provide cosmetic grade (compliant with regulations such as FDA and EU CosIng) and reagent grade (for laboratory research and development or analytical standards);Packaging Specifications:Small batches: 100g/bottle, 500g/bottle, 1kg/aluminum foil bag (sealed to prevent moisture absorption);Large batches: 25kg/cardboard drum (lined with polyethylene bags, suitable for industrial transportation and storage);Safety Tips: It is a non-hazardous substance, but avoid inhaling dust (which may irritate the respiratory tract); it is recommended to wear a dust mask during operation. Avoid mixing and storing with strong oxidants (such as potassium permanganate) to prevent oxidation reactions.Specification Company profile Exhibition Packing & Delivery FAQ
