SONGSORB® 2908 PW UV Absorbers

This product is a substituted benzoate that absorbs UV radiation and, through a reversible chemical rearrangement, dissipates the energy as heat. It provides antioxidant activity both during thermal processing and in moderately elevated temperatures as a result of its radical-scavenging mechanism. This product exhibits excellent compatibility, low color contribution, low volatility, and low toxicity. It is an excellent UV light stabilizer for olefins, particularly pigmented opaque formulations, for applications such as pipes, drums, sheeting, marine, and garden. It is usable in combination with phenolic and phosphite antioxidants, and with SONGLIGHT® Light Stabilizers to optimize performance in outdoor applications. The product synergizes well with UV Absorbers and antioxidants that function as hydroperoxide decomposers.

SONGSORB® 3260 PW UV Absorbers

This product is a strong absorber of UV radiation in the 300 - 400nm region. It has a high degree of photostability and offers greater absorption of longer wavelengths when compared with SONGSORB® 1000. This product is affected less by alkalinity and metals and has less effect on metal driers and metal catalysts because of its higher dissociation constant. It is recommended for use at levels of 0.2% - 1.0% in PP, PE, polybutylene, polyesters, and coatings. This product is usable in combination with SONGNOX® Antioxidants and SONGLIGHT® Light Stabilizers to optimize performance in outdoor applications.

SONGSORB® 3270 PW UV Absorbers

This product is a strong absorber of UV radiation in the 290 - 400nm region. It has a high degree of photostability. This product exhibits good initial color, low volatility, excellent stability to heat and light, superior wash fastness, and resistance to gas fading. It is particularly suitable for PE, PP, PU, cold-cured polyesters, dyes, and pigments. The low pKa and high hindrance of the phenolic group result in low sensitivity to metal-containing ingredients in formulations. It is usable in combination with SONGNOX® Antioxidants and SONGLIGHT® Light Stabilizers to optimize performance in outdoor applications.
