7031 Polyester Electrical Non-Woven Fabric (also known as Plain Non-Woven Fabric) is a high-performance insulating material engineered for the demanding requirements of the electrical industry. This non-woven fabric is manufactured from premium polyester fibers that undergo a rigorous full-combing process to ensure maximum uniformity and structural integrity.

The production involves a specialized filament impregnated adhesive drying process, which results in a smooth, consistent surface and exceptional longitudinal strength. Its unique construction balances a lightweight, thin profile with high tensile durability, making it an ideal choice for compact electrical components.

Key Features and Advantages

• Superior Insulation: Provides reliable dielectric properties to prevent electrical leakage and short circuits.

• High Tensile Strength: Optimized longitudinal strength ensures the tape can withstand mechanical stress during winding and application.

• Low Elasticity: Offers excellent dimensional stability, ensuring it remains taut and secure without stretching over time.

• Chemical Resistance: Non-corrosive properties ensure compatibility with various resins, varnishes, and metallic components.

• Precision Profile: The ultra-thin and lightweight design allows for high-density layering in tight spaces.
