High-performance specialty fibers and engineered thermal components to meet specific thermal capabilities and chemistries in iron and steel applications.
For more than 75 years, we have provided Fiberfrax® ceramic fiber products used for furnace insulation in the heat-treating and metalworking industries. Heat-treating and metalworking furnaces heat steel products to a temperature that is suitable to forge and form steel into finished product forms. Today, we offer the broadest range of high-performance, high-temperature insulation products, innovative low bio-persistent fiber chemistries, and engineered thermal components to meet various thermal capabilities and specific physical characteristics for iron and steel applications. We manufacture more than 150 different Fiberfrax, Insulfrax®, and Isofrax® products, as well as engineered thermal components, all of which provide proven and effective thermal management, filtration, and fire protection solutions to reduce energy consumption and provide significant cost savings for our clients in the iron and steel industry.

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.
