GRI™C insulation is the newest member of the GRAFSHIELD™ high-temperature insulation product line. GRI C offers superior energy efficiency through an engineered internal structure and temperature uniformity through consistent quality. Featuring carbon-fiber-composite (CFC) facing on one or both sides, GRI C insulation is engineered to deliver sustained product life in harsh furnace environments. The excellent abrasion resistance of the CFC facing makes the product a superb choice for metal hardening processes involving high-pressure gas quenching, where traditional insulation solutions are susceptible to damage from the incidental impacts that occur during loading/unloading, maintenance and production operations.
