Silplate® 1212S is a unique structural insulating board for use in high-temperature applications. While in service, Silplate 1212S maintains high compressive strength and low thermal conductivity. Physical properties of this material remain unchanged up to the maximum use temperature of 1200°C (2192°F), providing stability to the entire refractory lining system. Therefore, potential joint attack to the working lining is minimized. Silplate 1212S provides excellent chemical stability, resisting the attack of most acids and corrosive agents except hydrofluoric, phosphoric, and concentrated alkalis. Made from high-purity materials, Silplate 1212S has very low Fe2O3 content.

Product Information Sheet
Silplate Structural Insulating Board
Silplate® boards were specially developed by Unifrax for backup applications that require a very high-strength refractory insulating material. Common applications are for backup in ladles or tundishes that are used in molten metal transfer. Using Silplate boards for backup applications can significantly reduce steel shell cold face temperatures. Because of Silplate’s high use temperature limit, in many cases a thinner refractory cross section may be used and this practice results in increased vessel capacity.
