FFKM Rubber O Ring

FFKM Rubber O Ring

O Ring is the most common mechanical design for sealings, because it's a low cost, simple to be made, reliable functionality products.

FFKM Rubber O Ring refers to a terpolymer of perfluoro(methyl vinyl) tetrafluoroethylene, and perfluoroolefin. Also known as FFPM.

FFKM Rubber O Ring has elasticity and thermal and chemical stability of PTFE. The long-term working temperature is -39~288 degrees Celsius, and the short-term temperature can reach 315 degrees Celsius. It still has a certain degree of plasticity below the brittle temperature, hard but not brittle, and bendable. Except for swelling in fluorinated solvents, it is stable to all chemicals.

FFKM O-ring has poor processing performance. Used in occasions where fluorine rubber is incompetent and the conditions are harsh. To produce seals resistant to various media, such as rocket fuel, umbilicals, oxidizers, dinitrogen tetroxide, fuming nitric acid, etc., for use in aerospace, aviation, chemical, petroleum, nuclear energy and other industrial sectors.
