UV Stabilizers play an essential role in protecting and improving the quality of polymers and lubricants in the chemical industry. By protecting against the harmful effects of UV radiation, UV stabilizers help to extend the life of products, increase their reliability and reduce the overall cost of maintenance and replacement. A general distinction can be made between UV absorbers and radical scavengers. While UV absorbers interact directly with the incident UV radiation, radical scavengers bind the radicals formed by the influence of UV radiation. Consequently, a complete UV protection system consists of both a UV absorber and a radical scavenger.
UV stabilizers in the lubricant industry are particularly relevant in the manufacture of lubricants for outdoor use or in applications exposed to UV radiation. Lubricants such as metalworking fluids (MWF), greases or biolubricants must be able to maintain their effectiveness and stability even under UV radiation.
