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.

Key Properties: Colorless, tasteless, non-toxic; can meet FDA and other food-grade material requirements when unadded. Due to crystalline nature, the original color is milky white translucent with better transparency than PE. Low specific gravity of 0.9, making it one of the lightest plastics compared to water. Good toughness, especially repeated bending resistance, commonly known as “100-fold rubber”. Better heat resistance than PE, up to 120°C. Good resistance to hydrolysis; can be sterilized by high-temperature steam. Excellent chemical resistance, particularly to acids; suitable for storing concentrated sulfuric acid. Outdoor use is susceptible to light, UV, and aging. Modified PP Material By filling PP with carbon fiber, the rigidity and modulus are increased, reducing deformation caused by shrinkage. However, toughness decreases. Adding anti-UV or anti-aging agents improves outdoor performance, and adding flame retardant materials improves fire resistance.
