Expanded graphite has good corrosion resistance, high and low temperature resistance, good compression resilience and high strength. Expanded graphite is very easy to absorb oil, organic molecules and hydrophobic substances. After oil absorption, it floats on the water surface, which is easy to catch and recycle, can be reused and easy to handle.
Expanded graphite is a kind of basic material. Expanded graphite can be used to make strip, packing ring and packing gasket. It can also be directly pasted on various metal surfaces to effectively solve the problem of gas-phase sealing. Long strip can be directly used to make packing and spiral wound gasket.
Expanded graphite gasket can be widely used for static sealing of flange joints of pipes, valves, pumps, pressure vessels, towers, heat exchangers, condensers, etc.
It has good expansibility, high temperature resistance, heat insulation, lubricity and chemical stability.
