Calcium Carbonate is a commonly used filler in plastics compounding. Typically, a stearate coating is required to improve dispersibility of this additive into the compounding process. Traditional coating processes can form undesirable agglomerates that increase the amount of additive required. Due to the high costs of stearates, companies looked for an effective, continuous coating process that reduces operational costs. In addition, traditional melted liquid stearate systems present maintenance and operation problems due to re-freezing in the pumping and liquid handling systems.
