Insulation Portfolio

GRI™ Insulation

GRAFSHIELD™ GRI™ insulation is a rigid and sturdy material made with 100% bonded carbon fiber. This product has been a mainstay in several industries for the processing of high-value materials and parts. GRI™ insulation panels feature outstanding durability, typically providing years of service. The strength-to-weight ratio is such that the product features low thermal mass and easy handling while being strong enough to withstand rapid temperature and pressure fluctuations. Available in a variety of panel sizes as well as customized parts, GRI™ insulation is easily machined and able to hold fine detail.

GRI™G Insulation

GRAFSHIELD™ GRI™G and GRI™GG insulation panels feature GRI™ insulation faced on one or both sides with GRAFOIL® flexible graphite. The GRAFOIL® sheet layer performs several functions for enhanced insulation performance. This layer acts as a reflector and spreader of heat, increasing furnace energy efficiency as well as hot zone temperature uniformity. The lifetime of the insulation panel is maximized, due to the low permeability of the GRAFOIL® sheet layer to reactive gases. Furnace cleanliness is assured, as the GRAFOIL® sheet layer prevents the escape of particles from the insulation layers.

GRI™C Insulation

GRAFSHIELD™ GRI™C and GRI™CC insulation panels feature GRI™ insulation with carbon fiber composite (CFC) facing on one or both sides. The CFC face sheet provides superior impact and abrasion resistance, ensuring longer product life in harsh environments. These products are designed for use in high pressure gas quenching processes as well as other applications that require a high degree of protection for the insulation component.
