Owens Corning Fiberglass Roving - Fiberglass Material, Industrial Use, White Color | Suitable For Pultrusion And Filament Winding Applications

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. Its 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: 23002700 MPa (varies by type and test method).

Interlaminar shear strength: Typical dry shear 6070 MPa.

Shear strength retention after boil (72 h): 8095 %.

Linear Density / Yield:

Expressed as Tex and yield (higher Tex = heavier fiber strand). Example yields include 113 (4400 Tex), 250/207 (20002400 Tex), etc.

Filament Diameter:

Typically 1624 m, 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).

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.

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.
