,Insulating Castable 800°C
Our LDSIN Series Insulating Castable is specifically formulated to provide superior thermal insulation as a monolithic lining or backup layer. By incorporating lightweight aggregates such as perlite, vermiculite, expanded clay, mullite, or bubble alumina, we create a castable with significantly reduced bulk density and thermal conductivity. This series covers a broad working temperature range from 800°C to 1700°C, offering a versatile and easy-to-install solution to minimize heat loss, improve furnace efficiency, and reduce energy consumption across diverse industries.

- Exceptional Thermal Insulation: Very low thermal conductivity creates an effective thermal barrier, drastically reducing heat loss through furnace walls and lowering operational fuel costs.
- Significantly Reduced Heat Storage: The low density and high porosity lead to minimal heat absorption, enabling faster furnace heat-up and cool-down cycles, which increases production flexibility.
- Lightweight Structural Advantage: Substantially lowers the overall weight of the refractory lining, reducing the load on the furnace steel structure and foundation.
- Wide Temperature Service Range: A comprehensive portfolio from LDSIN08 to LDSIN15 ensures a suitable grade for both moderate and extreme temperature applications.
- Monolithic Installation: Provides a seamless, joint-free insulating layer when cast in place, eliminating gaps that can become heat leakage paths.
This castable is ideally applied as:
- Backup Insulation Layer: Behind dense hot-face refractories in various furnaces, kilns, boilers, and incinerators to improve overall wall efficiency.
- Secondary Insulating Lining: In areas where primary insulation is needed but direct slag/abrasion contact is limited.
- Heat-Treating Furnaces: For lining batch and continuous furnaces where temperature uniformity and energy savings are critical.
- Petrochemical Heaters: As insulation in reformer and cracking furnace walls.
- General Thermal Equipment: Any application requiring a cast-in-place, lightweight insulating barrier.
In an era of rising energy costs and stringent efficiency standards, our Insulating Castable offers a direct path to operational savings and improved thermal performance. Its monolithic nature allows for design freedom in complex geometries, while its lightweight properties enable more economical furnace designs. It's not just an insulation material; it's a tool for building more sustainable and cost-effective thermal processes.
