To produce this coated filler, a solution of stearic acid is sprayed onto dry calcium carbonate. Then it is milled to get an even coating of the particles. The result is a beautiful, hydrophobic white filler ready for use in all sorts of plastic appliions. Be careful when you handle it though.
Fused Calcium Stearate is used as a lubricant and acid scavenger in polyvinyl chloride and other polymers. PMC Biogenix routinely assists its customers in choosing the appropriate grade for their appliion based upon particle size characteristics, amount of pigment present, residual alyst and specific handling requirements.
