Black Conductive Films
One of the more innovative uses for carbon black pigments in the plastics industry is in the electronics field. Products in this industry are called electrically conductive compounds. Since few plastic resins are inherently conductive, it is necessary to add special fillers to the plastic matrix to give them the desired conductive characteristics.
Over the years, carbon blacks have proven to be one of the most versatile functional fillers for plastics. In addition to providing electrical conductivity to the plastic compound, they also provide lasting protection against ultraviolet light degradation. Carbon blacks function as a moderately low cost pigment producing various shades of black in the final product. In many product formulations the plastics compounder can achieve several property combinations in one product.
The selection of the proper carbon black to use in the production of conductive compounds is based not only on the final properties of the particular compound desired, but also on the specific properties of the carbon black. The key carbon black properties are particle size, structure, and purity. These critical elements of the carbon black are then combined with various polymer carrier resins in the compounding process to produce the finished compound.
Benefits of Black Conductive Films:
- Excellent dispersion
- Integrity of the carbon black structure or network
- Consistent particle size
- Specific resistance
- High: <10 ohm-cm
- General: 10-100 ohm-cm
- Antistatic >1000 ohm-cm
