It is made of PAN fiber through high temperature graphitization. It has excellent properties such as high strength and high modulus. Used as a reinforcing material or matrix material in sealing, construction, machinery and other industries. Specification available：1 K, 3K, 6K, 12K, 24K and 48K filament or foil.
Compressed asbestos sheet are generally cheap, convenient. But the biggest trouble is the charring of rubber and packing, and the low temperature will result in the loosen of material. and finally cause leakage in the joint part or in the shim itself, and agglo-merating, smoking, and the planking are more easy sticking on the flange. Beside, asbestos will cause heavy pollution. So the high-strengh graphite sheet and non-compressed asbestos sheet will be used instead of asbestos materials.
