E-glass direct roving is made directly from a 2000 tips or a 4000 tips bushing. Direct roving are primarily used in filament wind. Pultrusion (such as pultruded rod, pipe, tanks, etc. ) and other fiberglass products(such as woven roving, chemical resistant grating, etc. )
Direct roving is made in one manufacturing step with a reinforcement sizing. 2000 strands or 4000 strands of filaments are bonded efficiently into a single strand. The tension of each glass fiber in the strand is uniform. There is low fuzz, quick wet and excellent mechanical properties.
