Behind this phenomenon, ultraviolet (UV) radiation is silently \"degrading\" the materials. UV absorbers are essentially \"invisible sunscreens\" specifically designed for polymer materials. They absorb harmful UV rays from sunlight and convert them into harmless heat, thus protecting plastics, coatings, rubber, and other materials from \"sunburn\" and aging.","thumbnail_url":"https:\/\/changhongchemical.com\/wp-content\/uploads\/2026\/01\/UV-Absorber-2.webp","thumbnail_width":3462,"thumbnail_height":1699}
