DESCRIPTION:
Reinforced Graphite Sheet(For Cylinder Gaskets)
It is formed by mechanically rolled-forming or high temp glue sticking expanded graphite sheets together with metal plate.
It has good compressibility and resilience, excellent sealing property, for microscopic surface irrgeularities and long working life,ecnomic.
It is mainly used for making cylinder gaskets of engines and punching into all kinds of sealing gaskets.
Tanged Mechanically rolled-forming
It can be used for making Reinforced graphite packing rings too.
