Conductive Carbon Black is a specially processed form of carbon black that is used to enhance the electrical conductivity and electrostatic dissipation of polymers, coatings, and films. It is widely used in applications that require antistatic properties or the ability to conduct electricity without compromising material strength or performance.
| Property | Typical Value |
|---|---|
| Appearance | Black powder |
| Particle Size | 10 – 40 nm |
| Surface Area | ≥ 1000 m²/g |
| Bulk Density | 0.2 – 0.3 g/cm³ |
| Electrical Conductivity | ≥ 10 S/cm |
| Purity | ≥ 99% |
| Challenge | Conductive Carbon Black Solution |
|---|---|
| Electrostatic build-up causing damage to sensitive components | Provides effective dissipation of static charge |
| Poor conductivity in polymer composites | Enhances surface conductivity without affecting material properties |
| Complicated dispersion of conductive additives | Easy dispersion and incorporation into various polymer matrices |
| Limited application in high-temperature environments | Stable performance across a wide temperature range |
Q1: Is Conductive Carbon Black suitable for use in food-grade applications?
Conductive Carbon Black is not food-grade and should not be used in food-contact materials.
Q2: How is Conductive Carbon Black incorporated into polymers?
It is typically added during the compounding or extrusion process at 1% – 5%, depending on the conductivity requirements.
Q3: Will Conductive Carbon Black affect the optical clarity of the material?
Yes, it will impart a black color to the material, so it is better suited for opaque or black-colored products.
