Product Overview
P-80 occupies a practical middle ground in our spherical carbon portfolio. With an 80% hardness rating, it offers sufficient mechanical integrity for most industrial applications while avoiding the density and cost penalties of ultra-high-hardness grades. This makes it the economical choice for large-volume users who don't face the most abrasive operating conditions.
The pelletized manufacturing process creates uniform cylindrical or spherical particles with consistent dimensions. This regularity ensures predictable bed packing and flow distribution, simplifying system design and reducing the engineering margin typically required for irregular media.
