This tape is made from glass fiber cloth using a no-weft (no crosswise threads) construction, coated with high-temperature resistant adhesives such as phenolic or epoxy resins. The no-weft design makes the tape denser, smoother, and more durable, improving its electrical insulation and mechanical properties.
Key Features and Performance
| Feature | Description |
|---|---|
| High Electrical Insulation | Prevents short circuits and leakage, suitable for high-voltage applications. |
| Heat Resistance | Can withstand temperatures up to 200°C or higher, ideal for motors, transformers, and industrial machinery. |
| Mechanical Strength | Strong tensile strength, high abrasion resistance, smooth surface suitable for winding or layering. |
| Chemical Resistance | Resists oils, solvents, and most industrial chemicals. |
| Easy to Process | Can be cut, wrapped, layered, or laminated with other insulation materials. |
3. Advantages of No-Weft Structure
Smoother Surface: Easier to wrap around coils or components without wrinkles.
Higher Density: Better electrical insulation and mechanical protection.
Consistent Thickness: Ideal for precision applications in transformers and motors.
4. Applications
| Application | Use Case |
|---|---|

| Industrial Machinery | High-temperature insulation for mechanical parts. |
5. Choosing the Right Tape
When selecting an electrical insulation no-weft glass cloth tape, consider:
Operating Temperature – Ensure the tape withstands your equipment's maximum working temperature.
Voltage Rating – Higher voltage applications require thicker, denser tapes.
Adhesive Type – Choose adhesives compatible with your equipment and environment (phenolic for high heat, epoxy for chemical resistance).
Tape Width and Thickness – Select according to the coil, wire, or component dimensions.
Manufacturer Certification – Look for ISO, RoHS, or other quality certifications to ensure reliability.
6. Storage and Transportation Tips
Store in a cool, dry, and clean environment, away from direct sunlight.
Avoid exposure to moisture, dust, and chemicals.
Keep rolls in original packaging until use to prevent contamination.
Maintain stable temperature during transport to avoid adhesive degradation or deformation.
