Metallized Carbon Corporation's Metcar Grade M-58 recently received approval from the Food and Drug Administration (FDA), allowing it to be used in food contact applications such as dry-running food mixer seals to provide lower seal friction and longer seal wear life.
Metcar grade M-58 is an electro graphite base material that contains a special additive to reduce friction and improve the dry-running wear rate. Available fully machined to the customer’s drawing specifications, Metcar Grade M-58 primary seal rings can be used in temperatures between minus 30 and 800 degrees F.
It is anticipated that Metcar Grade M-58 will also be useful in many other machine part applications where an FDA-approved, self-lubricating material with low friction and long wear life is required. For FDA-approved bearings, seal rings, vanes, rotors, end plates, piston rings, valve seats and other machine parts that must run submerged in beverages or liquefied foods, Metcar carbon-graphite grades that are impregnated with thermal-setting resin, copper, tin bronze or nickel chrome are used.
For pharmaceutical applications, several Metcar grades have passed the tests required for U.S. Pharmacopeia Class VI approved materials.
