Foundry, Castings & Refractories
High-Temperature Vermiculite for Foundry, Castings, and Refractory Applications
Delivering Superior Thermal Insulation, Fire Resistance, and Durability for Harsh Industrial Environments
Industry Overview – Foundry, Castings & Refractories
Vermiculite is a lightweight, chemically inert mineral essential for high-temperature insulation and refractory applications in foundry and metal casting industries. It is widely used to insulate ladles, moulds, and furnaces and to protect refractory linings due to its excellent thermal insulation and fire-resistant properties. Vermiculite withstands temperatures up to 1100°C without degradation, providing stable, long-lasting protection in the harsh conditions of metallurgy and refractory environments.
Key properties and uses include:
- High heat resistance suitable for temperatures up to 1100°C
- Low thermal conductivity for effective insulation and energy conservation
- Chemical inertness ensuring compatibility with molten metals and refractory materials
- Lightweight and easy to handle, reducing operational load and improving safety
- Non-toxic and asbestos-free alternative to traditional insulating materials
