Perfluoroelastomer (FFKM) Hygienic Gaskets

Perfluoroelastomer (FFKM) hygienic gaskets are entirely fluorinated, created to conquer particular sealing challenges in the food, dairy, pharmaceutical, biomedical and life-science industries.
The supreme Perfluoroelastomer (FFKM) is perfect for SIP and CIP cleaning systems. Perfluoroelastomer (FFKM) hygienic gaskets are created for sealing applications in which chemical resistance and high-temperature performance are crucial, consequently, they can resist solvents, amines, and steam.

The exceptional cross-linking configuration adopted in all Perfluoroelastomer (FFKM) hygienic gasket grades guarantees compatibility with almost all chemicals. The molecular formation of Perfluoroelastomer (FFKM) is very similar to PTFE, ensuring eminent thermal durability and chemical resistance. This allows users to rationalize onto a single material grade throughout all applications.

X-Ray and Metal Detectable Hygienic Seal Gaskets

X-Ray and Metal Detectable seals is a scope of metal detectable elastomer compounds created particularly to meet the most rigorous requirements of the pharmaceutical and food processing industries. The hygienic seals have been tested and proven for use at leading pharmaceutical producing units.

Seals and gaskets to fit IDF Gaskets, RJT Seals and DIN11851 are also available from M Barnwell Services.
