• Speciality Graphites

Flexible graphite sheets

Flexible Graphites are manufactured under Flexograf brand. High quality natural graphites are made to form intercalation compounds and are rapidly heated in 800?C. The rapid heating results in rapid expansion of the particle up to 300 times due to decomposition of intercalation compound. The expanded graphite powders are formed graphite sheets buy rolling or compression moulding. No binder is used. These sheets are chemically resistant and can be used in high temperature applications just like artificial graphites. Specialities include: can be used in high temperature up to 2500?C in vacuum, 600?C in oxidising temperature; vacuum up to 750 bar; pressure up to 750 bar; and pH value 0-14. Applications: flange gaskets, valve body and bonnet seals; exhaust pipe gaskets, fluid level gauge seals, pump gear case seals, gaskets for continuous casting and cylinder head gaskets.
