Grafoil® Flexible Graphite begins as graphite flake which is chemically
expanded and then rolled into sheets. Those Grafoil® sheets are then
stripped into tape or rolled and cut into gasket material (which we cut
gaskets from) or packing. The tape form is often used to make die formed rings buy
wrapping the Grafoil® around a mandrel and then forming it with a
die. Grafoil® cannot be machined.
Because Grafoil® is so conformable it takes on the shape of any opposing
flange which is why it seals so very well. With it's 0-14 ph capability
it's compatible with most chemicals. From a temperature standpoint Grafoil©
is also very flexible. Compatible with Cold (-400 F) to very hot (5400
F in Non-oxydizing atmosphere).850 F in oxydizing atmosphere. Grafoil®
is also available in Oxidation resistant grades offering 975 F rateing.
