Carbon Black comes in many different varieties. The
carbon black that works perfectly in truck tires is not the right choice for
conductive compounds. Selecting the carbon black with just the right features
is the first important step towards a successful end product.Pigment Carbon Black
The most important factor affecting the electrical
performance of carbon black is its structure. Particle size and porosity also
have an impact on the electrical behavior of the electrically conductive
compound.
Factors that improve electrical conductivity:
- High structure: high structure means that the
carbon black agglomerates form long and branched chains. Such a structure
is ideal for conductive compounds – the required conductivity can be
reached with lower loading levels.Carbon Black N330
- Small particle size: smaller size means higher
electrical conductivity. If the particles are small and relatively uniform
in shape, their surface area is larger than otherwise. Extra conductive
carbon blacks, with the smallest particle size, provide the highest
electrical conductivity.
- High porosity: higher particle porosity enables better electrical conductivity.
