What is high-purity flexible graphite?

SGL Carbon’s standard quality high-purity flexible graphite foils und sheets contain less than 0.15 % ash. Such low ash contents are demanded by the challenging processes and systems in high-temperature applications applied especially in the semiconductor, solar or ceramic industries. Post purification of high-purity flexible graphite allows even for production of ultra-high purity grades with ash contents down to only 5 ppm.

SIGRAFLEX high-purity expanded graphite foil and sheets are smart solutions for heat treatment processes like hardening, carbonizing and brazing, hot press molding and sintering, for quartz glass and crystalline silicon production as well as for various other furnace applications.

SIGRAFLEX materials are predestined to be used in high-temperature technology due to their unique properties. Not only do they improve the performance of high-temperature systems and processes, but also allow for increasing their efficiency, minimizing energy consumption as well as increasing the lifetime of furnace parts.
