Multifex-MM® Uncoated

Ultrafine precipitated calcium carbonate. Is a 0.07 micron uncoated calcite particle, rhombohedral in shape. The extremely small particle size results in high surface are, but only moderate oil absorption. Builds true thixotropic rheology in filled systems, and contributes to polymer reinforcement. Also used as nucleating agent in emulsion polymerization. Used in rubber reinforcement and natural rubber detackification in thin film products.
