SIGRAFLEX^® Liners, Diffusion Barriers, Insulation and Heating Elements

SIGRAFLEX products made from expanded natural graphite are predestined to be used for semiconductor crystal growing at high temperatures in aggressive environments – in particular due to their softness and flexibility, inertness, impermeability, their excellent high-temperature and corrosion resistance as well as outstanding thermal and electrical conductivity.

To protect insulation and other graphite furnace components made e.g. from SIGRATHERM^® soft or rigid felt from outgassing of production parts and to avoid undesired convection, SIGRAFLEX flexible graphite can be used as gastight protective liners and diffusion barriers: Building of deposits and dendrites and corrosion or oxidization of the graphite furnace parts are thus prevented and their service lives significantly extended.
