Fiberglass yarn is made from fine glass fibers. It features high strength, good heat resistance, and excellent electrical insulation. With low moisture absorption, it maintains stable performance in various environments. This yarn can be woven into fabrics or used in composites. It's commonly used in industries such as aerospace, construction, and electronics for reinforcement and insulation purposes. 

 Discover the exceptional quality and adaptability of our Fiberglass Yarn, engineered for a wide range of industrial and electrical applications. Crafted from ultrafine 4-13 micron filaments twisted into high-strength, uniform strands, this yarn offers outstanding durability, heat resistance, and electrical insulation properties.  

Our Fiberglass Yarn is available in multiple specifications—including ECD900, ECD450, ECE450, ECG150, and ECE225—tailored to meet diverse requirements. With customizable filament diameter, tex number, twist levels (TPI/TPM), and ply configurations, it seamlessly adapts to weaving, reinforcement, and insulation needs. Key advantages include:  
- Exceptional Thermal & Chemical Resistance: Withstands high temperatures and harsh environments, making it ideal for electrical insulation, PCB textiles, and industrial fabrics.  
- Lightweight Yet Robust: Delivers superior tensile strength and dimensional stability without adding bulk.  
- Flexible Packaging Options: Choose between small paper bobbins (1.5 kg) for precision electrical uses or large plastic bobbins (7-8 kg) for weaving and textile production. Coatings include paraffin wax for enhanced insulation or starch oil/silane for industrial applications.  

Whether for manufacturing composites, reinforcing materials, or insulating electrical components, our Fiberglass Yarn ensures consistent performance, ease of processing, and long-term reliability. Its versatility extends to industries like aerospace, automotive, construction, and electronics.
