Features & Advantages
- High tensile strength and stiffness for structural reinforcement
- Low fuzz and excellent unwinding performance for high-speed processing
- Good dispersion and resin wet-out for superior mechanical bonding
- Corrosion and moisture resistant, ideal for harsh environments
- Thermal and electrical insulation properties make it suitable for demanding composite systems
- Low LOI for clean processing in thermosetting resins
Application Processes
Glass fiber rovings are suitable for the following processes:
- Pultrusion – for profiles, rods, rebar
- Filament Winding – for tanks, pipes, pressure vessels
- RTM (Resin Transfer Molding) – for automotive and electrical components
- Spray-up and Hand Lay-up – for marine, construction
- Weaving / Knitting – to manufacture woven roving and multiaxial fabrics
- Sheet Molding Compound (SMC) – when chopped into strands
Typical Applications
- Wind turbine blades
- GRP pipes and pressure vessels
- Electrical cable cores and insulation
- Automotive leaf springs, hoods, and panels
- Building reinforcement bars (GFRP rebar)
- FRP bridge components, ladders, gratings
Storage & Handling
- Store in dry and well-ventilated areas, temperature 15–35°C, RH < 65%
- Avoid direct sunlight, moisture, and mechanical stress
- Keep in original packaging before use
- Recommended shelf life: 12 months from production date
Quality Assurance
All roving products undergo full in-process and final quality checks:
- Tex verification and strand uniformity
- Moisture content and LOI testing
- Strand tension uniformity during unwinding
- Compatibility test with target resin system
