High Silica Twill Weave Tape | Silica Content >98%
Flexible High-Temperature Silica Tape for Thermal Insulation & Fire Protection
High Silica Twill Weave Tape (>98% SiO₂) is a premium high-temperature insulation tape engineered for applications requiring greater flexibility, smooth surface finish, and excellent conformability.
Manufactured from continuous high-purity silica fibers and woven in a twill weave construction, this tape provides superior drape, higher tear resistance, and reliable thermal insulation in extreme heat environments.
Designed for continuous operating temperatures up to 1000°C and short-term exposure up to 1200°C, high silica twill weave tape is widely used for wrapping curved surfaces, exhaust systems, pipes, fire protection assemblies, and high-temperature sealing applications.
Key Performance Advantages
- Silica Content: >98% (Ultra-High Purity SiO₂)
- Continuous Temperature Resistance: Up to 1000°C
- Short-Term Heat Exposure: Up to 1200°C
- Twill Weave for Superior Flexibility & Drapability
- Higher Tear Resistance Than Plain Weave
- Smooth Surface Finish
- Non-Combustible, Non-Asbestos & Halogen-Free
The twill weave structure allows the tape to conform easily around bends, corners, and irregular surfaces while maintaining mechanical strength.
Tape Construction & Engineering Benefits
High Silica Twill Weave Tape is produced from high-purity silica yarns converted through a controlled leaching process to achieve >98% silica content. The twill weave pattern offers:
- Enhanced flexibility compared to plain weave
- Improved resistance to tearing and edge fraying
- Better surface finish for wrapping and sealing
- Stable performance under thermal cycling
Compared to plain weave tape, twill weave tape is preferred where complex shapes or curved installations are involved.
