Rulon® 641 (White) Sheet, Rod, Tube, Parts

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

Rulon® 641 is white in color and FDA/USDA & USP Class VI compliant and specifically developed for food and drug applications. Rulon ® 641 is designed to run dry without any moisture or lubrication.

Rulon® 641 offers excellent wear at elevated temperatures, runs against all mating materials. Used primarily in food processing applications. Resistant to caustic wash downs, steam.
