Flexible Graphite Sheet (C000205)



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.
