20m³ OFFLINE - FLUORINATION

Fluorination of plastic surfaces with reactive gases for permeation reduction

The technology used is suitable for treating surfaces of plastic fuel tanks (PFT) with the help of fluorine gas mixture (10% F2/N2) and changing the surface properties in such a way that a desired reduction of permeation of fuels from the PFT into the environment and thus the emission of fuel vapors is significantly reduced.
