How Light Stabilizers Protect Polymers from UV Degradation

How Light Stabilizers Protect Polymers from UV Degradation

When polymers are exposed to various environmental factors like UV light, heat, oxygen, light degradation would happen, causing problems, such as yellowing, cracking, reducing the performance and function. In order to enhance the durability and to extend the service life, it is necessary to add UV absorber and Hindered Amine light stabilizer (HALS) to prevent degradation caused by UV light, improving weather resistance and reliability in various applications. Plus, the combination of HALS and UV absorber offer synergistic effects to prevent against surface and functional defects.
