Non-Ferrous Oxygen Absorbers

A non-ferrous or non-iron oxygen absorber is a type of oxygen scavenger or absorbent that is specifically designed to remove oxygen from a sealed environment in a variety of applications where iron contamination must be avoided. In some instances, traditional oxygen absorbers that utilize iron-based (ferrous) compounds may cause discoloration or other undesirable effects, making non-ferrous oxygen absorbers, which do not contain iron, preferable.

These absorbers typically consist of a mixture of materials that react with oxygen, either through oxidation or chemical adsorption processes. The exact composition can vary depending on the requirements of the application. Common materials used in non-ferrous oxygen absorbers include ascorbic acid (vitamin C), sodium sulfite, activated carbon, and various metal oxides. These materials react with oxygen to form stable compounds, effectively reducing the oxygen content in the surrounding environment.

Non-ferrous oxygen absorbers are often used in situations where iron contamination is a concern, such as in the packaging of sensitive products like food, pharmaceuticals, or electronics. They are valuable in extending the shelf life of products by preventing oxidation reactions, which can lead to spoilage, degradation, or loss of efficacy. They are also used in various industrial processes where oxygen removal is necessary to maintain product quality or prevent corrosion. Non-iron absorbers are valued for being odor free and metal detector safe.
