The principal raw material for the expandable graphite is a high quality crystalline flake graphite. Expandable graphite belongs to a group of products called intumescents. The main property of intumescents is their ability to expand when heated.
Applications:
i) additive in plastic and bituminous roofing membranes;
ii) used in the manufacture of high performance seating foam;
iii) in speciallised steel production, it acts as exfoliating media in hot topping compounds;
iv) the finer grades can be used as exothermic powder covering in foundry coating applications.
v) intumescent coating and sealing materials.
