Roy-Tuff 9021: A better way to deliver fiber

Roy-Tuff 9021 is a compounded and opened Aramid pulp which has maximized surface area and allows for rapid dispersion into a variety of viscous materials. The degree of openness allows the maximum utilization of Aramid and amorphous silica properties. Best results are achieved if unopened product is used within one year.
