High Temperature Silica Yarns for RTD Cables (1000°C) | DOMADIA™
When RTD Cables Fail, Temperature Is Usually the Culprit
High-temperature environments don’t give second chances.
In steel plants, furnaces, kilns, power stations, and petrochemical units, RTD cable failure often starts not with the sensor—but with insulation breakdown.
That’s where High Temperature Silica Yarns for RTD Cables step in.
DOMADIA™ supplies high-purity silica yarns engineered to withstand continuous temperatures up to 1000°C, protecting RTD cables where conventional fiberglass or ceramic insulation simply can’t survive.
What Are High Temperature Silica Yarns?
High Temperature Silica Yarns are textile-grade insulation yarns made from high-purity amorphous silica (SiO₂), designed specifically for extreme thermal environments.
When used as braiding, wrapping, or reinforcement for RTD cables, these yarns provide:
- Thermal stability at 1000°C
- Electrical insulation integrity
- Resistance to thermal shock
- Long service life in harsh industrial zones
DOMADIA™ silica yarns are widely used in critical temperature measurement systems where failure means downtime, scrap, or safety risk.
Chemical Composition of Silica Yarns
DOMADIA™ High Temperature Silica Yarns are manufactured with tightly controlled chemistry to ensure consistent performance.
| Component | Typical Content |
| Silicon Dioxide (SiO₂) | ≥ 94–96% |
| Alumina (Al₂O₃) | Trace |
| Calcium & Magnesium Oxides | Trace |
| Iron Oxide (Fe₂O₃) | < 0.1% |
High SiO₂ content is the key reason these yarns maintain structural integrity and insulation properties at 1000°C.
Key Properties That Make Silica Yarns Ideal for RTD Cables
1. Extreme Temperature Resistance
DOMADIA™ silica yarns operate continuously at 1000°C without melting, shrinking, or losing insulation performance.
2. Electrical Insulation Stability
Even at elevated temperatures, silica yarns maintain high dielectric strength, protecting RTD signal accuracy.
3. Low Thermal Conductivity
Heat transfer to the RTD conductor is minimized, reducing measurement drift and sensor damage.
4. Excellent Thermal Shock Resistance
Rapid heating and cooling cycles do not crack or degrade the yarn structure.
5. Non-Combustible & Inorganic
Silica yarns do not burn, emit toxic fumes, or degrade in oxidizing atmospheres.
