Product Description

Product Description

Flexible graphite Sheet , Graphite Foil , Graphite paper , Graphite Tape ,

Flexible graphite material, also known as flexible graphite paper or flexible graphite sheet , is made of natural graphite flakes after chemical treatment and then heated to high temperature to form graphite worms. The density of this worm like graphite powder is about 0.003g/cc.

Then the flexible graphite coil is formed by rolling. The expanded graphite coiled material does not contain binder and filler, so it has high purity, good corrosion resistance, radioactivity resistance, high / low temperature resistance, good compression resilience, self lubrication and impermeability, and is suitable for sealing low-pressure parts. Graphite coil and metal sheet can be compounded into various forms of graphite composite plate.

What is graphite sheet?

What is flexible graphite rolls?

Graphite sheet provides superb sealing properties for high temperature, high pressure transfer of gases, liquids, steam, chemicals and corrosives. In high purity high crystal natural graphite flakes are produced which are processed into constant foils under special acid and thermal treatments. Fuel cell companies use this material as a separator layer on solid wastes and gaseous wastes. The expanded graphite crystals are then deposited into foil in a calendaring process without any resins and binders.

Flexible graphite rolls, also known as flexible graphite foil rolls, are made from high-purity natural flake graphite as the core material. They undergo processes such as chemical interlayer treatment (injecting interlayer agents to change the structure of the graphite layers), high-temperature instantaneous expansion (typically at 800-1000°C, the volume expands by several times, forming "worm-like" expanded graphite), and roll pressing to form a flexible foil-like graphite material. Then, they are processed through winding techniques to produce rolled products.

Product application:

1. it can be used as graphite packing ring material
2. it can be combined with metal sheet to form graphite composite sheet  and cut into sealing gaskets of various shapes
3. it is directly used to make various low-pressure gaskets or high-temperature insulation pads after being processed into thick plates
