The item that is being fluorinated is put into a sealed reactor. It is then exposed to a predetermined amount of elemental fluorine gas under specifically controlled conditions. With specific parameters in place they are able to accurately produce various levels of fluorination.
The fluorine chemically bonds to the chain-like molecules on the outermost surface of the container being fluorinated. This reaction forms a permanent thin fluorocarbon polymer surface layer which has higher chemical stability. This provides the container a superior barrier for hydrocarbon solvents. It reduces permeation and scalping of a range of fuels, chemicals, solvents, flavors, and fragrances. Fluorination will often reduce in many cases long term swelling and paneling through weight loss of product. Fluorination combines the cost effectiveness of polyethylene with greater chemical resistance to many solvents, agricultural chemicals, cleaning products, foods, pharmaceuticals, and cosmetics. We always suggest that the end user test their product with the fluorinated containers to determine suitability.
