The Mississippi Lime PolyCal^® O Calcium Oxide family of products is produced for the Rubber and Plastics Industries where tight sizing and reactivity control are essential.

There are three types of PolyCal^® O Calcium Oxide manufactured at our plant in Ste. Genevieve, MO:

• PolyCal^® OF is designed as a desiccant for polymer, plastic and rubber processing.  The small particle size, efficient absorption properties, and fast reactivity of PolyCal^® OF result in excellent moisture control for demanding applications.
• PolyCal^® OS is designed as a desiccant for rubber, plastic and polymer processing.  The controlled particle size, efficient adsorption properties and slow reactivity of PolyCal^® OS result in optimum moisture control for demanding applications.
• PolyCal^® OFT15 is an ultra fine calcium oxide designed for rubber, plastic and polymer processing.  PolyCal^® OFT15 acts as efficient moisture scavenger due to the combination of its controlled top size, high purity, reactivity and very small particle sizing.

All products are available to be shipped via rail or truck.  The PolyCal^® OS and PolyCal^® OF Calcium Oxide are also available in 50# bags packaged in either Ste. Genevieve, MO or with one of our packaging partners.  Special packaging and/or bulk bags can be accommodated through the same repackagers.
