Royflexa Rubber
1 / 5
Description: It is made of High carbon phosphorus flake graphite which is chemically treated and rolled by high temperature expansion. It is the basic material for manufacturing all kinds of graphite seals.
Main usage: Widely used in electric power, petroleum, chemical industry, instrumentation, machinery, diamond and other industries for dynamic and static seals in machines, pipes, pumps, and valves. It is an ideal replacement for rubber, fluorine plastic, asbestos, and other traditional sealing materials.
