　　REINFORCED EXPANDED GRAPHITE SHEET

　　This product is made from materials of three layers. At the middle of the composite plate is a stainless steel plate and on both sides expanded graphite plates,Then,through specially pressing or sticking process, after that, the product is done. This is a kind of sealing packing with excellent comprehensive properties; it overcomes the disadvantage of being squeezed out from and or sticking into flanges. This kind of pickings has good compressibility and resilience, small stress relaxation ,fine compensation function for unevenness of sealing surfaces and long working life. These plates are suitable for making gaskets of cylinders for air compressors, internal combustion engines and pickings for different kinds of pipings and flanges.
