CalCarb^® AC3 is a 3-micron median particle size, off-white natural calcium carbonate filler. PolyCal^® AC3 is produced at our Ste. Genevieve, MO facility from a limestone deposit of exceptional consistency. CalCarb^® AC3 is especially suitable for PVC and LDPE plastic compounds where its 15 micron top-cut, low silica content, and spherical shape combine to give low processing equipment wear and high impact resistance. No dispersants or grinding aids are used in the manufacturing of CalCarb^® AC3.

CalCarb^® AC3 is available to be shipped via rail or truck. Special packaging and/or bulk bags can be accommodated through our packaging partners.
