Unifrax Foamfrax® RG Insulation

Foamfrax® RG (Refractory Grade) Insulation is an extension of the Foamfrax Insulation product line. Foamfrax RG Insulation is a combination of refractory ceramic fiber or soluble fiber, refractory cement, and a high-temperature binder solution combined in the field using the proprietary Foamfrax process. The resultant product form is a high-density, ceramic fiber or soluble fiber based material engineered for refractory backup lining applications. Foamfrax RG can be gunned easily around a variety of refractory anchor systems and air sets within 24 hours. Traditional refractory materials (castables, plastic and brick) may be installed over Foamfrax RG once the product air sets.Isofoam® RG Insulation is similar to Foamfrax RG Insulation, but utilizes Unifrax's patented Isofrax® soluble fiber chemistry as the fiber component of the finished product.Foamfrax RG Insulation and Isofoam RG Insulation may be applied in ducts, stacks and furnace hearths, in units operating at temperatures below 1800°F (982°C).Principal ApplicationsBackup behind brick, plastic, refractory, and castableAnnealing furnace basesDuct, flue, and stack liningsHeat treat furnace, kiln car decksIncinerator floors, process heatersInformation Provided by Unifrax I LLC
