What is Long Glass Fiber (LGF)?

Long glass fiber reinforced plastics (LFT) are engineered materials in which long glass fibers and additives are incorporated into a base thermoplastic. This significantly improves mechanical strength, heat resistance, dimensional stability, and the overall performance of the material.

Why Reinforce with Long Glass Fiber?

• High heat resistance: LFT significantly increases the thermal performance, especially for nylon-based plastics.
• Reduced shrinkage & higher rigidity: Fiber reinforcement restricts polymer chain movement, improving dimensional stability and stiffness.
• Improved impact resistance: Reinforced plastics are less prone to stress cracking and have better toughness.
• High strength: Long glass fibers increase tensile, compressive, and bending strength.
• Flame retardancy: Most LFT materials are self-extinguishing due to additives and fiber content.

Why Choose Long Glass Fiber over Short Glass Fiber?

• Longer fiber length significantly enhances mechanical properties.
• High specific stiffness and strength with excellent impact resistance, ideal for automotive applications.
• Superior creep resistance and dimensional stability for precision parts.
• Excellent fatigue resistance for long-life components.
• Improved stability under hot and humid environments.
• Minimal fiber damage during molding due to relative fiber movement in the mold.
