Offline fluorination is a batch process that takes place in a vacuum (vacuum chamber). The systems can perform both barrier fluorination and OXI ™ fluorination. The two variants of the method differ in the presence of oxygen in the process gas atmosphere within the chamber.
Barrier fluorination creates “compaction” by introducing the fluorine atoms on the walls of plastic containers. This reduces migration, diffusion and permeation through the vessel wall.
In OXI ™ fluorination, oxygen is added to the chamber in addition to the fluorine / nitrogen mixture. Not only fluorine atoms are embedded in the polymer chains of the plastic surface, but also oxygen. This results in carbonyl, hydroxyl and other oxygen-containing groups with which the functional groups of coating materials can interact. This improves the following characteristics of your product depending on the application target:
