The content of carbon black used in polystyrene particles is 2-2.6%.
Of course, the specific amount of carbon black added to PS polystyrene particles depends on the specific production process and the performance of the carbon black used, such as If you use highly pigmented carbon black to add less to PS polystyrene particles, if you use low-color pigment carbon black to add more to PS polystyrene particles.
Pigment Carbon Black for polystyrene can be used in many places, such as ordinary polystyrene, expanded polystyrene (EPS), high impact polystyrene (HIPS) and syndiotactic polystyrene (SPS).
Most industries need to add carbon black dispersants when using carbon black, but usually carbon black powder in carbon black products is easier to disperse than granular carbon black, and before carbon black is added to the base material, do a good job Do a good job of grinding and grind the carbon black finely, which is conducive to the dispersion of carbon black.
