Dielectric High Silica Braided Rope
Low-Moisture Braided High Silica Rope for Electrical & High-Temperature Insulation
Dielectric High Silica Braided Rope is manufactured from high-purity silica fibers (SiO₂ ≥96–98%) using a tight braided construction that delivers excellent dielectric strength, very low moisture absorption, and long-term thermal stability.
This product is specifically engineered for electrical insulation, RF-transparent sealing, and high-temperature gap filling, where non-conductivity and moisture resistance are essential.
The braided structure ensures uniform density, superior flexibility, and improved mechanical integrity compared to twisted or loosely knitted ropes.
Key Performance Advantages
- High Silica Content: ≥96–98%
- Excellent Dielectric Strength & Electrical Insulation
- Dielectric-Grade Low Moisture Absorption
- Low Dielectric Constant & Low Electrical Loss
- Continuous Operating Temperature: Up to 1000°C
- Tight Braided Construction for Uniform Density
- High Flexibility & Compression Recovery
- Non-Conductive, Non-Magnetic & RF-Transparent
- Chemical, Thermal Shock & Oxidation Resistant
- Non-Asbestos & Environmentally Safe
The braided structure provides better shape retention and sealing efficiency, even under vibration, pressure, and thermal cycling.
