Standard properties of manufactured graphite include thermal stability, thermal conductivity, natural lubricity and chemical resistance to fluids. Flexible graphite combines these properties with the added characteristics of flexibility, compatibility, conformability and resilience. These characteristics differentiate flexible graphite from other forms of graphite, making it a superior, high-performance sealing material.

This material data has been provided by Matmatch.

"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.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
