    Application of High Modulus Glass Fiber

    Tensile Strength: High Modulus Glass Fiber with tensile strength above 3.5 GPa is used in aerospace composite structures, where it enhances load-bearing capacity and reduces structural weight.

    Modulus of Elasticity: High Modulus Glass Fiber featuring a modulus of elasticity exceeding 85 GPa is used in wind turbine blades, where it improves blade stiffness and operational efficiency.

    Filament Diameter: High Modulus Glass Fiber with a filament diameter of 9 micrometers is used in automotive body panels, where it delivers superior impact resistance and dimensional stability.

    Thermal Stability: High Modulus Glass Fiber demonstrating stability up to 600°C is used in high-temperature electrical insulation, where it ensures long-term insulation reliability and safety.

    Density: High Modulus Glass Fiber with a density of 2.6 g/cm³ is used in marine hull laminates, where it provides high strength-to-weight ratio for improved vessel performance.

    Chemical Resistance: High Modulus Glass Fiber with increased resistance to acids and alkalis is used in chemical storage tanks, where it prolongs service life and minimizes maintenance requirements.

    Moisture Absorption: High Modulus Glass Fiber exhibiting moisture absorption below 0.2% is used in sports equipment, where it maintains mechanical properties under humid conditions.

    Packing & Storage
    Packing High Modulus Glass Fiber is packaged in 25 kg moisture-resistant woven bags with inner polyethylene liner for optimal protection and storage.
    Container Loading (20′ FCL) Container Loading (20′ FCL): Loads approximately 22-24 metric tons of High Modulus Glass Fiber, securely packaged on pallets, moisture-protected.
    Shipping High Modulus Glass Fiber is shipped in sealed, moisture-proof packaging such as cartons, woven bags, or drums to prevent contamination and preserve quality. It should be handled with care to avoid damage, stored in a cool, dry place, and protected from sunlight and mechanical stress during transportation.
    Storage High Modulus Glass Fiber should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and sources of moisture. Packaging should remain sealed until use to prevent contamination and physical damage. Store away from strong acids, alkalis, and other corrosive materials. Ensure stacking prevents crushing or deformation of the fibers for optimal performance during application.
    Shelf Life High Modulus Glass Fiber has an indefinite shelf life if stored in original, unopened packaging, away from moisture and direct sunlight.
