biTinuv

biTinuv is a brand of UV absorbers and light stabilizers manufactured by the company BASF. These additives are incorporated into polymers and other materials to protect them from degradation caused by ultraviolet radiation. UV radiation can break down chemical bonds within materials, leading to discoloration, loss of mechanical strength, and premature failure. biTinuv products work by absorbing UV light and dissipating its energy as heat, preventing it from damaging the underlying material.

The biTinuv range includes various types of UV absorbers, such as benzophenones and benzotriazoles, each with specific absorption characteristics and compatibility with different polymer systems. In addition to UV absorbers, the biTinuv portfolio also includes Hindered Amine Light Stabilizers (HALS). HALS function by scavenging free radicals that are formed during the photo-oxidation process, thereby interrupting the degradation chain reaction.

These additives find application in a wide array of industries, including automotive, construction, packaging, textiles, and coatings. For example, they are used in automotive paints to prevent fading and cracking, in building materials like window profiles and roofing membranes to extend their lifespan, and in plastic packaging to protect product contents from UV-induced damage. The specific biTinuv product chosen depends on the type of polymer, the intended application, and the expected environmental exposure. BASF provides technical support to help customers select the optimal stabilization package for their needs.
