Permeation Resistance

Regulations are getting tougher – not only must automobiles not pollute via the exhaust, they must not allow fuel vapors to permeate through seals and gaskets. Through seal permeation resistance is and will be an important consideration going forward. Precix®’s F86 GF-based High-Fluorine Fluorocarbon offers the best permeation resistance in the industry today.
