Description

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.

This material data has been provided by Advanced Graphite Materials.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
