Advantages:
The product not only has all the characteristics of graphite, but also has light weight, softness, thermal stability, high and low temperature resistance, anti-corrosion, oil resistance, lubrication, compressibility, elasticity, and excellent sealing performance. It can be used for long time under extreme use condition, with low maintenance cost, so it is an ideal substitute for asbestos gasket.
Usage:
The product is a basic material for making various graphite composite plate (according to clients’ need, metal flat plate, metal toothed plate and metal netting, etc., can be added to the graphite layer), graphite strip, packing, sealing gasket, cylinder gasket, etc., or it sticks to various metal surface to improve sealing performance. It is widely used for dynamic and static sealing in machinery, pipes and pumps and electric power generation, petroleum industry, chemical, light industry, etc., and is an ideal sealing material to replace traditional rubber, asbestos, and plastic.
Working temperature:-200℃~1650℃(in non-oxidizing media),-200℃~850℃(in oxidizing media).
