Perlite-Silica Composite Board 900°C
High-temperature perlite-silica composite board rated to 900°C with enhanced binder matrix. Low shrinkage and stable thermal performance for glass melting furnaces, heat treatment furnaces, and ceramic kilns.
// Key Features
- High-temperature stability to 900°C with minimal linear shrinkage under cycling
- Silica-reinforced binder matrix for improved structural integrity at service temp
- Low thermal mass enables faster furnace heat-up and cool-down cycles
- Excellent resistance to thermal shock and spalling under repeated cycling
