Glass Fiber Chopped Strands Technical Data Sheet (TDS)
Glass Fiber Chopped Strands are high-performance reinforcement materials made by cutting continuous glass filaments into short lengths. They are designed for use in thermoplastics and thermosetting resins to improve mechanical properties such as tensile strength, dimensional stability, and thermal resistance.

Features & Advantages
- Excellent mechanical reinforcement — enhances tensile, flexural, and impact strength
- Fast resin wet-out — ensures homogenous dispersion during processing
- Good flowability and feeding behavior — suitable for extrusion and injection molding
- Low static buildup and low fuzz — improved cleanliness in compounding
- Corrosion and thermal resistant — ideal for harsh operating conditions
- Electrical insulation — stable dielectric properties over a wide frequency range
Processing Methods
Chopped strands are used in a variety of molding and compounding methods:
- Injection Molding — for automotive parts, home appliances, and power tools
- Extrusion Compounding — production of reinforced pellets or masterbatch
- Compression Molding — suitable for high-strength structural composites
- Hand Lay-up (in thermosets) — for reinforcement in putties, adhesives, and resins
Typical Applications
- Automotive: engine covers, battery trays, interior panels
- Electrical & Electronics: switch boxes, insulators, cable trays
- Appliances: washing machine panels, housings
- Industrial: pump housings, gratings, machine parts
- Construction: reinforced concrete additives, FRP rebars
- Marine: boat fittings, compound profiles
Storage & Handling
- Store in a dry, cool, and ventilated environment
- Avoid direct sunlight, moisture, and excessive stacking
- Recommended temperature: 15–35°C; RH < 65%
- Use within 12 months of manufacture for optimal performance
- After opening, seal bags tightly to avoid moisture pickup
Packaging
