Pre-shrunk high silica fabric is a high-performance textile material made from silica-rich fibers (typically >96% SiO₂) that have undergone a pre-shrinking treatment. This process enhances the fabric’s dimensional stability and thermal performance, making it ideal for use in high-temperature and fire protection applications. Below are the key benefits of using pre-shrunk high silica fabric:
Pre-shrunk high silica fabric can withstand continuous temperatures up to 1000°C (1832°F) and short-term exposure to even higher levels. It is commonly used as:
Welding blankets
Furnace curtains
High-temperature insulation wraps
The pre-shrinking process stabilizes the fabric, ensuring minimal shrinkage during actual use. This prevents dimensional deformation in:
Heat shielding
Aerospace insulation
Industrial fire curtains
Despite exposure to high temperatures, the fabric maintains mechanical strength and flexibility, making it suitable for:
Heat shields for engines and turbines
Silica fabric is naturally flame-retardant and resistant to most acids, alkalis, and chemical splashes, making it reliable in:
Chemical processing plants
Foundries and steelworks
Pre-shrinking also enhances surface smoothness and reduces fraying, making it easier to:
Cut, sew, and fabricate
Integrate into multilayer insulation systems
Being a non-asbestos material, high silica fabric is a safer and environmentally compliant alternative for thermal and fireproof applications.
Thermal insulation covers for pipes and valves
Heat shields for automotive and aerospace industries
Protective clothing for foundry and welding workers
