Silica-coated glass fiber is an advanced composite material that combines the strength and flexibility of glass fiber with the high-temperature resistance and durability of silica. This combination makes it an ideal choice for various industrial applications where thermal insulation, chemical resistance, and mechanical stability are crucial.
What is Silica-Coated Glass Fiber?
Silica-coated glass fiber consists of a core of woven or non-woven glass fibers that are coated with a layer of silica. The silica coating enhances the fiber’s ability to withstand extreme temperatures, improve chemical resistance, and reduce friction. Depending on the application, different thicknesses and coating formulations are used to optimize performance.
Key Properties and Benefits
- High-Temperature Resistance – The silica coating provides excellent thermal stability, allowing the material to endure temperatures up to 1000°C (1832°F)* without degradation.
- Enhanced Chemical Resistance – The coating protects the underlying glass fiber from chemical attack, making it suitable for use in harsh environments, including exposure to acids, alkalis, and solvents.
- Mechanical Durability – The combination of glass fiber strength and silica coating reinforcement provides superior mechanical properties, including resistance to abrasion and wear.
- Low Thermal Conductivity – Silica-coated glass fiber serves as an effective thermal barrier, making it an excellent choice for insulation applications.
- Electrical Insulation – The material exhibits excellent dielectric properties, making it useful in high-temperature electrical insulation applications.
