LaserMark additives (often searched as laser marking pigments) are laser-responsive functional additives designed to generate durable, high-readability contrast on plastics. This decision tree helps engineers and designers select the appropriate LaserMark grade based on substrate color, absorption behavior, marking mechanism, and application requirements.
Percolation threshold is the minimum loading at which a conductive additive forms a continuous electronic network in a composite or electrode. Below this threshold, conductivity increases slowly; above it, conductivity rises sharply. For battery electrodes, a lower percolation threshold means higher energy density and lower inactive material content.
Carbon black relies on particle-to-particle contact to form conductive paths. Its low aspect ratio means a large amount is required to bridge gaps between active materials, leading to higher percolation thresholds and increased inactive mass.
Carbon nanotubes form long-range conductive networks due to their high aspect ratio. A small amount of CNT can span large distances within the electrode, dramatically reducing the percolation threshold compared with carbon black.
