Product Description Reinforced graphite composite board is made of high-carbon natural flake graphite after chemical treatment and high temperature rolling from expanded graphite composite board. It is also known as high-strength graphite reinforced graphite sheet or plate and is made of metal sprint tooth plate or metal mesh plate or metal flat plate and pure graphite paper by composition and rolling. The general forms of composite reinforced composite boards include sprint board, screen boad, flat board, etc. The main features are good thermal stability, high strength and no cold flow and can be made into a variety of shapes and complex geometry round gaskets such as water gauge gasket, cylinder gasket, exhaust gasket with rib heat exchanger gaskets, etc. Key performance indicators:

Product Description Flexible graphite sheet and roll is made of high-carbon natural flake graphite after chemical treatment and high temperature rolling from expanded graphite composite board. Expanded graphite sheet does not contain binder and filler, therefore, it has features of very high purity, good corrosion resistance, radiation resistance, resistance to high / low temperature, low creep relaxation, flexibility, excellent performance, self-lubricating and non-permeable ability suitable for low pressure parts sealing. Graphite roll and sheet metal can be combined into various forms of graphite composite panels. Key Features: The following product performance data refer to the sheet density of 1.0g / cm3, and other density products can be processed in accordance with customer requirements.
