CAL CARB PCC NANO INFORMATION
This PCC is specially produced to nanometric size. It is surface treated with stearic acid to increase its ease of dispersion. Consider this nanometric PCC a high performance filler and functional additive. It will enhance the physical properties of a variety of polymeric matrices: in Rigid PVC applications it improves impact, strength and weatherability. In injection molded and extruded parts it produces an exceptional smoothness and gloss. It will lower the gas permeability of the product, a benefit to sealants.

BENTONITE PAPER MAKING SLURRY INFORMATION
This slurry is specially designed for papermaking on modern, high speed machines. It is made using high swelling sodium Bentonite in a single component suspension of anionic nano-particles. Its chemistry is controlled by its very large surface area. Its physical properties can be controlled in the papermaking process. The P-Slurry is typically used in conjunction with starch as an aid in retention and drainage applications.
ADVANTAGES:
Increased paper uniformity and dry strength
Simple, single addition rather than balancing multiple additions
Linearly scaleable performance
Compatible current papermaking techniques
Reduces or eliminates high priced polymers
