WHAT IS INERT NITROGEN?
Air is about 79% nitrogen which is a close cousin to oxygen on the chemical periodic table. However, by virtue of it’s atomic structure, nitrogen is chemically unreactive (inert) in rubber. Oxygen’s atomic structure makes it aggressively reactive (ie: during high quality welding or brazing operations, the area is often bathed in nitrogen to eliminate oxidation contamination. Nitrogen is blown into many packaged foods before the container is sealed to reduce oxidation (rancid change) of the contents.
