Sinosorb® UV 2908 is a substituted benzoate that absorbs ultraviolet radiation and through a reversible chemical rearrangement, dissipates the energy as heat. Provides antioxidant activity
both during thermal processing and in moderate elevated temperatures due to radical scavenging mechanism.
Sinosorb® UV 2908 can be used in combination with phenolic & phosphite antioxidants, and HALS to optimize performance in outdoor use synergizes well with UV absorbers and antioxidants which function as hydro-peroxide decomposers.
