High Silica Braided Rope | Silica Content >98%
High-Temperature Braided Silica Rope for Thermal Sealing & Fire Protection
High Silica Braided Rope (>98% SiO₂) is a premium high-temperature sealing and insulation product engineered for extreme heat resistance, excellent flexibility, and long-term durability.
Manufactured from continuous high-purity silica fibers and braided into a dense, round construction, this rope provides superior thermal insulation, low thermal conductivity, and outstanding resistance to flame, molten metal splash, and chemical attack.
Designed for continuous operating temperatures up to 1000°C and short-term exposure up to 1200°C, high silica braided rope is widely used for furnace sealing, expansion joints, fire doors, high-temperature gasketing, and thermal insulation systems.
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
- Excellent Thermal Insulation & Low Heat Loss
- High Flexibility & Compression Recovery
- Outstanding Flame, Spark & Molten Metal Resistance
- Non-Combustible, Non-Asbestos & Halogen-Free
The braided construction ensures uniform density, mechanical stability, and easy installation in sealing and gasketing applications.
Rope Construction & Engineering Benefits
High Silica Braided Rope is produced using high-purity silica yarns converted through a controlled leaching process to achieve >98% silica content. The braided structure offers:
- High mechanical integrity under compression
- Excellent resilience for repeated thermal cycling
- Minimal shrinkage at elevated temperatures
- Smooth surface finish for improved sealing performance
This construction makes the rope ideal for static and dynamic high-temperature sealing environments.
