Chinese Graphite Sheet Products

Chinese Flexible Graphite Sheet

Also known as flexible graphite, our sheet products are manufactured by using chemically-treated natural graphite, without the use of binders or resins, that result in flexibility and compression recovery rates that are unobtainable with conventional graphite.

Chemically stable in a wide range of temperatures (from -200 to 3200°C inert atmosphere), they also offer excellent in-plane thermal and electrical conductivity, making them ideal for either as a heat release or heat transfer material, in a variety of industrial uses.

They are also optimal in applications where fluids and lubricants need to be avoided, and/or when using counter materials and contacting parts. such as: gaskets, liners, kinetic & static seals, semiconductors, etc.

Our current product line features three different thickness ranges, and four grades:
