Introduction
E-glass direct roving is made directly from a 2000 tip bushing or a 4000 tip bushing. Direct Rovings are primarily used in filament  winding and pultrusion processes. Typical products are pultruded rod, pipe, tanks, woven roving and chemical resistant grating.
Product Characteristics
Direct Roving is made in one manufacturing step with a special reinforcement sizing. The glass fibers are bonded into a single strand. The tension of each glass fiber in the strand is uniform. There is low fuzz, quick wet out and excellent mechanical properties.
