      UV absorbers are compounds added to materials to protect them from the harmful effects of ultraviolet (UV) radiation. Ultraviolet radiation from the sun can cause serious damage to a variety of materials, including plastics, paints, textiles, and even human skin. The primary function of UV absorbers is to absorb UV rays and dissipate them as low levels of heat, thereby preventing degradation or other harmful effects of UV radiation.
      Important points about UV absorbers:
      Types of UV absorbers:
      Organic UV Absorbers: These are usually aromatic compounds that absorb UV radiation and convert it into heat energy. Examples include benzotriazole, benzophenone and triazine.
      Inorganic UV Absorbers: These include materials such as titanium dioxide (TiO2) and zinc oxide (ZnO), which scatter and absorb UV radiation. They are often used in sunscreens and paints.

      Application

      7 Jan 2019
      Plastics and Polymers: UV absorbers are added to plastics to prevent discoloration, loss of mechanical properties and embrittlement due to UV exposure.
      Coatings and Lacquers: They help prevent fading and chalking, thereby maintaining the appearance and integrity of painted surfaces.
      Textiles: UV absorbers are used in fabrics to protect the fabric from UV-induced degradation and to provide UV protection to the wearer.
      Cosmetics and Sunscreen: In personal care products, UV absorbers protect the skin from harmful UV rays, reducing the risk of sunburn and skin cancer.
      Mechanism of action: UV absorbers work by absorbing high-energy UV radiation and releasing it as low-energy heat. This process prevents UV radiation from breaking the chemical bonds in the material, thus protecting it from damage.

      Benefits

      Enhanced Durability: The material lasts longer and retains its properties when protected from UV radiation.
      Aesthetic Preservation: Colors and finishes remain vibrant and intact.
      HEALTH PROTECTION: In sunscreen, UV absorbers protect skin from harmful effects such as sunburn and long-term damage.

      Notes

      Compatibility: UV absorbers must be compatible with the materials they protect.
      Concentration: The effectiveness of UV absorbers depends on their concentration and distribution within the material.
      Stability: UV absorbers should be stable and not degrade over time or when exposed to UV radiation.
      In summary, UV absorbers play a vital role in extending the service life and maintaining the quality of various materials by protecting them from damage by UV radiation. They are used in a wide range of industries from plastics and textiles to cosmetics and coatings.
