Description:

Perfluoroelastomer is carbon-fluorine bond with one of the best thermal, oxidative and chemical stability of fluorinated polymers.

Advantages:

High reliability for dynamic and static applications and stability for aggressive media. Excellent chemical and thermal resistance due to the combination of between the carbon-atom and fluorine-atom.

Disadvantages:

Poor low temperature performance.
