Thermal Insulation Applications
High-Performance Fused Silica for High-Temperature Insulation Systems
Fused silica is widely used in thermal insulation applications due to its low thermal conductivity, excellent temperature resistance, and long-term stability in extreme environments.
Fused Silica for Thermal Insulation
Thermal insulation materials are critical for reducing heat loss, improving energy efficiency, and protecting equipment operating at high temperatures.
Thanks to its unique physical structure and high SiO₂ purity, fused silica is an ideal raw material for high-temperature insulation products used in industrial furnaces and thermal systems.
Typical Thermal Insulation Applications
Fused silica is commonly used in:
High-temperature insulation boards
Lightweight insulation panels
Furnace roof and wall insulation
Industrial kiln and furnace insulation systems
Backup insulation layers for refractory linings
It is suitable for industries such as metallurgy, glass, ceramics, petrochemical, and power generation.
