Benefits of Carbon Black Pigment
Increased surface area
Oxidation creates oxygen-containing groups on the surface of carbon black, increasing its specific surface area by up to 10 times. The increased surface area improves pigment loading and absorption, resulting in improved color intensity and opacity.
Improved dispersion
Oxidation changes the surface chemistry of the pigment, making it more compatible with solvents. This enhanced dispersion reduces agglomeration and ensures even distribution throughout the coating, resulting in a smooth, even finish.
Enhanced UV resistance
Oxidation introduces chemical bonds that absorb and dissipate harmful UV radiation. Post-treated carbon black pigments have excellent UV resistance by protecting the base resin, ensuring long-lasting protection against fading and degradation.
Improved thermal stability
Oxidation strengthens the pigment's structure and improves its thermal stability. This enhanced durability allows carbon black to withstand higher processing temperatures and harsh environments without compromising its performance.
Reduce carbon black migration
Oxidation forms an adhesive layer on the surface of carbon black to prevent migration and bleeding. This improved stability enhances the appearance of the coating by reducing staining and ensuring consistent color reproduction.
Types of Carbon Black Pigment
N series carbon black
N series carbon black is a carbon black with lighter color and smaller surface area. Because N series carbon black particles are smaller and have good fluidity and dispersion, they can be used in coatings, inks, rubber products, plastics and other fields. In addition, due to its purification treatment and surface modification, N series carbon black is often used as an additive for high-end food and pharmaceutical packaging materials.
S series carbon black
S series carbon black is another common type of carbon black. Compared with N series carbon black, it has a darker color and a larger surface area. S Series carbon blacks offer excellent wear resistance, electrical conductivity, and UV and chemical resistance. It is commonly used in areas such as automotive tires, rubber seals and industrial mufflers.
P series carbon black
P series carbon black is a carbon black with a very large surface and has good color enhancement properties, fluidity and suspension properties. Due to its high specific surface area and strong adsorption, P series carbon black is usually used in the fields of coatings, inks and cosmetics to provide excellent blackening effects and improve the texture of coatings.
F series carbon black
F series carbon black is a kind of carbon black that has been oxidized and has a high surface carboxyl content. The carbon black can be combined with resins and polymers to produce good affinity and compatibility, and has excellent tackification, stability and processing properties.

How is Carbon Black Pigment Used In The Textile Industry?
Colorant
One of the primary uses of carbon black pigment in the textile industry is as a colorant. It is used to impart deep black or gray shades to fabrics, yarns, and fibers. Carbon black's intense and stable coloration is especially useful in creating classic and timeless designs in garments, home textiles, and industrial fabrics. Its ability to produce rich, consistent hues ensures that the desired color remains vivid even after repeated washings and exposure to light, making it an ideal choice for long-lasting textiles.
UV stabilizer
Additionally, carbon black pigment serves functional purposes in textiles. It is commonly used as a uv stabilizer, protecting against the harmful effects of ultraviolet radiation from the sun. This is particularly important for outdoor textiles, such as awnings, outdoor furniture, and sports equipment, as it helps extend the lifespan of these products by reducing color fading and material degradation.
Conductive textiles
Another notable application of carbon black pigment is in conductive textiles. When incorporated into fabrics, carbon black can enhance their electrical conductivity, making them suitable for use in electronic textiles (e-textiles) and wearable technology. These conductive textiles have diverse applications, ranging from interactive clothing and smart textiles to medical monitoring devices, demonstrating the versatility and innovation that carbon black brings to the industry.
Durability and strength
Carbon black pigment also contributes to improving the durability and strength of textiles. It enhances abrasion resistance, tear strength, and overall mechanical performance when blended with polymers or incorporated into rubberized fabrics. This is particularly valuable in applications such as industrial workwear, protective clothing, and military textiles, where durability and resilience are paramount.
Paragraph 1: High black level and covering power
Carbon black pigments have extremely high blackness and can produce deep, rich black effects. They absorb light and barely reflect it, resulting in a very pure black color. In addition, carbon black has excellent hiding power and can effectively cover other pigments or base colors, making the surface appear uniformly black.
Paragraph 2: Robustness and Durability
Carbon black pigments are very strong and durable. They are resistant to external environmental factors such as light, oxidation and chemical corrosion. Therefore, carbon black pigments are often used in applications that require long-term stability and durability, such as paints, dyes, and pigmented inks.
Paragraph 3: Electrical conductivity and thermal stability
Carbon black pigment has good electrical conductivity and thermal stability. Due to its high conductivity, carbon black pigments are often used to make conductive materials such as printing inks, battery plates, and conductive rubber. At the same time, carbon black pigments also have excellent thermal stability and can maintain their color and performance in high temperature environments without being affected.
Five ways to dissolve Carbon Black Pigment
High Shear Mixing
Using a high shear mixer or homogenizer can help disperse the carbon black particles in the liquid medium. The intense mechanical force generated by the mixer can break up agglomerates and promote the dispersion of particles. This method is suitable for small-scale applications.
Wetting agents and dispersants
Adding wetting or dispersing agents to the solvent can improve the dispersion of carbon black particles. These chemicals reduce surface tension and promote wetting of the particles, allowing for better dispersion. Depending on the specific type of carbon black and solvent used, it is important to select the appropriate wetting or dispersing agent.
Ultrasonic treatment
Ultrasonic treatment uses high-frequency sound waves to generate cavitation bubbles. When the bubbles burst, they release local energy and help disperse carbon black particles. This method is particularly suitable for breaking up agglomerates and achieving better dispersion.
Premix and Stir
Premixing carbon black with a small amount of polymer or binder can facilitate particle dispersion. The mixture is then stirred or mixed vigorously to achieve proper dispersion.
Particle Size Distribution
In order to evaluate the quality of carbon black pigment, particle size dispersion is crucial. The size distribution of carbon black particles is determined using a variety of methods, including laser diffraction, sedimentation, and microscopy. Particle size has a direct impact on rubber compound qualities such as color intensity, dispersibility, and reinforcing capacity. In general, narrow size distribution is preferable to get the best color development and dispersion.
Surface Area
Carbon black's specific surface area, which is commonly calculated using the Brunauer-Emmett-Teller (BET) technique, offers important details regarding its dispersibility and reinforcing properties. Greater surface area is correlated with greater reinforcing characteristics and increased dispersion, increasing the end product's mechanical strength and durability.
Structure and Aggregate Size
The structure and aggregate size of carbon black particles, which have a substantial influence on their characteristics, are assessed using transmission electron microscopy (TEM) and scanning electron microscopy (SEM) techniques together with image analysis. Reinforcement, electrical conductivity, and dispersion properties are enhanced by a well-defined structure and regulated aggregate size.
Tint Strength
Tint strength gauges how well carbon black pigment can provide color to a certain substrate. By contrasting the intensity of a colored sample with a reference standard, it may be calculated. The higher the tint strength, the better the color development, which is crucial in applications like inks, paints, and coatings.
