Pigment Black 7 (Carbon Black)

What is Pigment Black 7?

Pigment Black 7, commonly known as carbon black, is a fine black powder produced by the incomplete combustion of hydrocarbons. It is one of the most widely used black pigments in industrial applications, offering strong tinting strength, excellent UV resistance, and good conductivity depending on grade.

Carbon black is used in coatings, plastics, inks, and rubber products where deep black coloration, durability, and functional performance are required. Its properties vary depending on particle size and structure, allowing it to be tailored for different applications.

Typical Applications

Pigment Black 7 is widely used in:

• Plastics and masterbatch
• Industrial and decorative coatings
• Printing inks
• Rubber products (tires, seals, hoses)
• Conductive and anti-static materials

In plastics and coatings, it provides deep black coloration and UV protection.
In rubber, it acts as both a colorant and reinforcing filler.

Key Performance Properties

1. High Jetness and Tinting Strength

Pigment Black 7 provides deep black color with strong tinting strength, allowing efficient pigmentation at relatively low loading levels.

2. Excellent UV Resistance

Carbon black offers outstanding resistance to UV radiation, helping protect polymers and coatings from degradation.

3. Good Dispersion Performance

With proper processing, it can be well dispersed in coatings, inks, and plastic systems to achieve uniform color.

4. Functional Performance (Optional Conductivity)

Certain grades of carbon black provide electrical conductivity, making them suitable for anti-static and conductive applications.

Advantage

1. Strong Color Performance

Provides deep black shade and high color strength across a wide range of applications.

2. Excellent Durability

Offers superior resistance to UV light and environmental exposure compared with many organic pigments.

3. Versatile Application Range

Suitable for plastics, coatings, inks, rubber, and functional materials.

Typical Limitations

1. Dispersion Complexity

Due to its fine particle size, achieving uniform dispersion may require appropriate processing techniques.

2. Dust Handling

Carbon black is a fine powder and requires proper handling to minimize dust during processing.

3. Property Variation by Grade

Performance varies significantly depending on grade, structure, and particle size, requiring careful selection.

Buyer Guidance

When selecting Pigment Black 7, buyers should confirm:

• Target application (plastics, coatings, inks, rubber, etc.)
• Required jetness (blackness level)
• Dispersion method and equipment
• Functional requirements (UV resistance, conductivity)
• Regulatory compliance

Providing detailed application conditions helps ensure correct grade selection.
