Nucap® 290W

Sulfur-functional hydrated aluminum silicate. It is a high brightness treated kaolin clay with the highest level of surface treatment that functions as a reinforcing filler / extender for elastomeric systems. It imparts the best mechanical properties and water resistance and its treatment aids dispersion in soft, low shear compounds such as stoppers and tubing. Silane treated clays mix in quicker manner and allows the formulator to reduce the amount of added silane. It appears as a spray dried beads or odorless white powder.
