Why impregnate carbon graphite?
Porous carbon graphite can be impregnated to reduce permeability, improve sealing behavior, modify mechanical properties or improve performance in a defined process environment. The correct impregnant depends on chemistry, temperature, friction pair, pressure and component geometry.
Resin impregnation
Options may include phenolic, synthetic or epoxy-based resin systems and other organic or inorganic compounds subject to application feasibility. Resin impregnation is commonly considered for seal and bearing components where reduced permeability and controlled properties are required.
Metal impregnation
Uploaded company content lists copper, antimony, bronze, nickel, ferrous, white-alloy and other material systems for specific requirements. Metal impregnation can change density, strength, thermal behavior and service capability, but selection must be application specific.
