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 works against stainless steel and aluminum without wear, is self-lubricating, and maintains performance from cryogenic to +450° temperatures.
