Graphite has unique chemical and physical features.
Raw graphite is porous and it is resistant to many aggressive chemicals in a wide temperature range.
It is used up tp 1800℃ in process industry.
Impregnated graphite Graphec is fully impervious and inert to a wide range of aggressive chemicals up to 220℃.
Thermal conductivity (up to 160 W / mK) is significantly higher than any other industrial material.
