Direct Roving is made in one manufacturing step with a special 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.
2. PROPERTIES & APPLICATIONS.
Properties: --Excellent choppability of Strand, --Fast and complete wet-out, --Good Affinity to Resin, --Good Strand Integrity, --Good Distribution, --Suitable Stiffness, --Even tension.
Direct roving is primarily used in filament winding, pultrusion (such as pultruded rod, pipe, tanks, etc) and other fiberglass products (such as woven roving, chemical resistant grating, etc).
