GRAFOIL is pure graphite. No fillers or no binders, nothing to leach out or harden. It is free from corrosion, embrittlement and aging. The gaskets and packing made from Grafoil can perform successfully even under extreme conditions.

They can withstand from -200° C to 1850° C or as high as 3000° C in the absence of oxygen.
They are resistant to all aggressive media such as highly concentrated acids, solvents and hot oils.
They are resilient across entire temperature range of any length of time.
They are not susceptible to cold or hot flow at the highest permitted surface pressure.
They are unaffected by radiation and are recommended for use in nuclear plants.
They are permitted to use in conjunction with oxygen.
They are physiologically inert.
Flange distortions are compensated.
