Fiberglass yarn is a fibrous material made from molten glass drawn into yarn through a textile process. Its main components are silicon dioxide (SiO₂) and other metal oxides (such as Al₂O₃, CaO, etc.), exhibiting inorganic non-metallic properties. The following is a multi-dimensional analysis:
Technical Principle:
The raw material is melted at 1450-1600℃ and then drawn at high speed through a platinum-rhodium alloy spinneret (the diameter of a single filament is typically 5-25 micrometers).
The fiber surface is treated with a coupling agent (such as silanes) to enhance its adhesion to resin.
Characteristics:
High Strength: Tensile strength can reach 3000-5000MPa, twice that of ordinary steel.
Corrosion Resistance: Resistant to acids and alkalis (stable in environments with pH 1-14).
Insulation: Volume resistivity > 10¹⁵Ω·cm.
Temperature Resistance: Long-term operating temperature -60℃ to 450℃.
Application Scenarios:
Construction Reinforcement: Concrete crack-resistant mesh, GRC decorative components.
Industrial Applications: Pipe winding yarn, insulating sleeve substrate.
Transportation: Lightweight automotive components (e.g., bumper frames).
Industry Standards:
Chinese Standard: GB/T 18369-2008 (Continuous Glass Fiber Yarn).
International Standard: ISO 2078 (Type code E-glass is general type).
Precautions:
Wear protective gloves during handling to avoid fiber irritation to the skin.
Store humidity should be <65% to prevent moisture from affecting the sizing agent's effectiveness. We currently have this product in stock.
