Rulon 641® | With USP Class VI Approval

Rulon 641
 

Rulon 641— the only filled PTFE material with USP Class VI approval for direct contact with human tissue and fluids — is a powerhouse in the medical and food processing industries. It offers excellent load and wear resistance plus good chemical resistance.  It can also withstand strict sanitation requirements, and its white, stain-resistant color indicates a sanitary compound.

Rulon 641 delivers:

  • Works against stainless steel and aluminum, without wear
  • Self-lubricating properties
  • Maintains performance from cryogenic to +450° temperatures
  • Meets medium load and speed requirements
  • PV rating of 10,000 (higher with intermittent service)
