Seeking eco-friendly UV-light stabilizers
Deadline : 2020-08-27
Polymers are continuously subjected to the action of different stress factors, such as oxygen, heat, UV light, mechanical stress, humidity, etc., during their processing and service life, undergoing overall oxidative degradation, that causes performance and property deterioration. To improve the resistance at high temperatures and long-term weatherability of the polymers during their manufacturing, synthetic antioxidants and UV-light stabilizers are added. Many of these established UV-light stabilizers are seemingly becoming a threat to human health, the environment and natural resources as they are evidently presence in our aquatic ecosystems and persistence in the environment. The company is seeking eco-friendly or/and alternative compounds suitable to be used as UV-light stabilizers for the plastic industry.
