Metcar Grade M-58 is approved by FDA for food and pharmaceutical applications
Metallized Carbon Corporation's Metcar Grade M-58 has received approval from the FDA so that it can be used in food contact applications. This will permit the use of Metcar Grade M-58 in dry running, food mixer seals to provide lower seal friction and longer seal wear life. For pharmaceutical applications, there are several Metcar Grades that have passed the tests required for U.S. Pharmacopeia Class VI approved materials.
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 -30 and 800 °F.
