UV Absorbers

          SONGSORB^® 2340 PW
SONGSORB 2340 is a strong absorber of ultraviolet radiation in the 300-400nm region and has a high degree of photostability. Particularly suitable for high surface area applications like films and fibers. Compared to other UVAs, Songsorb 2340 has a low volatility, making it especially for high temperature process applications including PET fibers and films, polycarbonate, POM, nylon, polyolefins, TPE, TPO and coatings. Can be used in combination with phenolic and phosphate antioxidants, and HALS to optimize performance in outdoor use. SONGSORB 2340 is FDA listed in 21 CFR 178.2010, Antioxidants and/or stabilizers for polymers.

          SONGSORB 7120 PW
SONGSORB 7120 is a substituted benzoate that absorbs ultraviolet radiation, and through a reversible chemical rearrangement, dissipates the energy as heat. It provides better initial color than benzotriazoles and exhibits a synergistic effect in combination with HALS. It can be used in combination with phenolic and phosphate antioxidants and HALS for thermal and light stabilization in outdoor use. Recommended for use at levels of 0.2% - 1% in polypropylene, polyethylene, TPO, PVC, EVA, unsaturated polyester ABS and AS. SONGSORB 7120 is FDA listed in 21 CFR 178.2010, Antioxidants and/or stabilizers for polymers.
