Flexible graphite sheet manufactured by Wealson is a binderless material. It can be used in high temperature environments and is resistant to most chemicals. It is very anisotropic with respect to characteristics such as gas permeability, electrical resistivity, and coefficient of thermal expansion and thermal conductivity.
Flexible graphite sheet can be used from cryogenic temperatures to very high temperature: up to 450°C in oxidising atmosphere and up to 2500°C in an inert atmosphere.
Flexible graphite is used to make
