Graphite Sheet

Rolled Flexible Graphite Foil, Electrode Thermal Conductive Graphite Foil, Erosion Resistant, High-Temperature Resistant Graphite Sheet, Graphite Paper Roll

Company Profile Flexible graphite Sheet , Graphite Foil , Graphite paper , Graphite Tape , Graphite Strip (paper) 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. Specification What is graphite sheet? 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. 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 Common specifications of graphite sheet : Width 1000mm or 1500mm, coil length 30,50,80m; Plate 1000mm or 1500mm; Coil thickness 0.15-1.0; Plate 1.0mm-5mm; Density, 0.8-1.25g/cm3, other special specifications can be requested by customers.
