Features & Benefits

Benefits
  • The wear characteristicss are approximately 5 times better than virgin PTFE
  • Low coefficient of friction compared to CAR/BZ compounds
  • Low abrasion when used against soft metal counterparts
  • Low hardness compared to standard compounds as CAR/BZ etc.
  • Product Highlights

    Graphite has good chemical resistance to corrosive environments and exhibits good wear and rubbing/sliding characteristics in dry and water applications. It also has a low CoF. It is commonly blended with carbon and PTFE.
