Quinto Technology (Lumby, B.C.) is now making available pilot quantities of a naturally occurring mica with average particle diameter of four micron. Most mica is produced in large flake form in North Carolina as a by-product of the production of kaolin, feldspar and silica. Larger mica flakes confer high stiffness, flexural strength and dimensional stability, but with some loss of impact strength. Ultrafine mica flakes restore lost impact properties. Because the mica is natural, high production costs to make ultrafine mica are spared, resulting in much lower cost to the customer.

Initially, two reinforcing grades and two pigment grades of the mica are being offered. A full-scale plant for mica production is under construction.
