Hubercarb® W3 by Huber Engineered Materials is a unique ground calcium carbonate-based filler with controlled fine particle distribution. It acts as an extender, gloss control agent, anti-slip additive, rheology modifier and densifier.
- Processed at huber's largest GCC plant in Quincy, Illinois.
- Exhibits high surface area, round particle shape, low moisture and low silica content.
- It is suitable for oilfield drilling fluids where its 99%+ calcium carbonate content yields almost complete acid solubility.
- Hubercarb® W3 is recommended for compression molded plastics, PVC compounds and other plastic applications.
