E - grade Fiberglass Cloth | Electronic Grade Glass Fiber Yarn Woven Fabric for PCB & High - End Insulation Applications
E-grade Fiberglass Cloth, also known as electronic-grade glass fiber fabric, is a specialized woven material fabricated from extremely fine electronic-grade glass fiber yarns. This fabric serves as the fundamental reinforcing material for producing Copper Clad Laminates (CCLs), which are essential substrates for Printed Circuit Boards (PCBs). It provides reliable structural support to ensure the performance and stability of PCBs and other advanced composite materials.
- Excellent Dimensional Stability: Maintains accurate dimensions under changing environmental conditions, ideal for applications requiring strict manufacturing tolerances.
- Outstanding Mechanical Strength and Toughness: Offers high tensile strength and impact resistance, enhancing product durability and longevity.
- Stable Electrical Insulation Performance: Provides consistent electrical insulation to prevent current leakage and ensure system safety.
- Exceptional Heat Resistance and Chemical Stability: Withstands high temperatures and resists chemical corrosion for prolonged service life in harsh environments.
- Uniform Resin Impregnation: Allows even resin absorption during composite manufacturing for consistent product quality.
Our E-grade Fiberglass Cloth has diverse applications in high-end industries:
- Printed Circuit Board (PCB) Manufacturing: Key reinforcing material for Copper Clad Laminates (CCLs), the foundation of PCBs.
- Fire Protection Industry: Used in fire-resistant boards and insulation materials.
- Wind Power Generation: Applied in reinforced components requiring thermal resistance and mechanical strength for wind turbines.
- Aerospace & Sectors: Employed in advanced insulation and structural parts for extreme conditions.

Our E-grade Fiberglass Cloth is carefully packaged to ensure safe transportation and storage:
- Standard Packaging: Rolled onto cardboard cores, wrapped with waterproof kraft paper or plastic film, and placed in sturdy export-grade cartons.
- Custom Packaging: Available upon request for large-scale orders or specific needs (palletized packaging, vacuum-sealed bags).
Proper storage guidelines to preserve fabric quality:
- Environmental Conditions: Store in dry, well-ventilated areas away from humidity and dampness.
- Temperature and Humidity: Keep away from direct sunlight, rain, heat, and flame. Recommended storage at 15-30°C (59-86°F) with ≤65% relative humidity.
- Handling Precautions: Prevent crushing, folding, or contamination during storage and transportation.
