The Importance of UV Absorbers in Polymeric Materials
Polymeric materials have become increasingly popular in various industries due to their unique properties such as flexibility, durability, and resistance to chemicals. However, prolonged exposure to UV radiation can cause degradation of these materials, resulting in discoloration, brittleness, and ultimately, failure of the product. This is where UV absorbers come in.
What are UV Absorbers?
UV absorbers are chemical compounds that are added to polymeric materials to protect them from UV radiation. They work by absorbing the UV rays and converting them into harmless heat, thereby preventing the degradation of the polymer. UV absorbers are particularly important in outdoor applications where the polymers are exposed to sunlight for prolonged periods.
