Fiberglass Roving

Owens Corning Fiberglass Roving “ Short Specification Overview 🵠Product Description Fiberglass roving from Owens Corning consists of continuous glass fiber strands gathered into a bundle without mechanical twist and sized for resin compatibility. It™s designed as a reinforcement for composites in processes such as pultrusion, filament winding, and weaving/knitting. Glass Type Made with Advantex corrosion-resistant E-CR glass (improved corrosion resistance vs. standard E-glass). 🔠Typical Reinforcement Form Single-end roving: Continuous strands wrapped and packaged for composite processing. 🔠Common Specifications While exact numbers vary by specific roving variant (e.g., 158B, 366, R25H), typical properties include: Mechanical Properties (example ranges): Strand tensile strength: 2300“2700 MPa (varies by type and test method). Interlaminar shear strength: Typical dry shear 60“70 MPa. Shear strength retention after boil (72 h): 80“95 %. Linear Density / Yield: Expressed as Tex and yield (higher Tex = heavier fiber strand). Example yields include 113 (4400 Tex), 250/207 (2000“2400 Tex), etc. Filament Diameter: Typically 16“24 µm, depending on Tex and product variant. 🪠Resin Compatibility Designed for polyester, vinyl ester, epoxy, polyurethane, acrylic, and in some sizing versions also thermoplastics (e.g., PP, HDPE). š™ï Features Excellent strand wet-out (fast impregnation by resin). Low fuzz / smooth run-out. Good mechanical properties in laminates. Multi-resin compatibility, increasing processing flexibility. 📠Packaging & Handling Single-end internal pull packages, often with Tack-Pak wrapping to aid run-out. Pallets can weigh 1 ton and are wrapped for protection. ðŸ Standards & Compliance Product is manufactured under quality systems (e.g., ISO 9001). Glass type meets ASTM D578 for E-CR glass. 🛠Typical Applications Filament winding (pipes, tanks, pressure vessels) Pultrusion (profiles, structural components) Weaving / knitting (fabrics for composites) General reinforcement in FRP parts.
