UV Absorbers

          SONGSORB^® 1000 PW
SONGSORB 1000 is a strong absorber of ultraviolet radiation in the 390 to 400nm region, and has a high degree of photostability (photochemical energy absorbed in the ultraviolet region is dissipated as thermal energy). SONGSORB 1000 is a particularly effective UV protector in acetals, acrylics, cellulose esters, PC, polyesters, polystyrene, and PVC. It also provides UV protection to ABS, unsaturated rubber polymers, PU and epoxies and can also be used in combination with phenolic and phosphate antioxidants, and HALS to optimize performance in outdoor applications. SONGSORB 1000 is FDA listed in 21 CFR 178.2010, Antioxidants and/or stabilizers for polymers.

          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 2908 PW
SONGSORB 2908 is a substituted benzoate that absorbs ultraviolet radiation and dissipates the energy as heat. It provides antioxidant activity both during thermal processing and in moderate elevated temperatures due to radical scavnging. SONGSORB 2908 exhibits excellent compatibility, low color contribution, low voatility and low toxicity. It is an excellent UV stabilizer for olefins, particularly pigmented opaque formulations for applications such as pipes, drums, and sheeting. It can also be used in combination with phenolic and phosphite antioxidants and HALS to optimize performance in outdoor use, and synergizes well with UV absorbers and antioxidants which function as hydroperoxide decomposers. SONGSORB 2908 is FDA listed in 21 CFR 178.2010, Antioxidants and/or stabilizers for polymers.

          SONGSORB 3200 PW
SONGSORB 3200 is a strong absorber of ultraviolet radiation in the 300 to 400nm region with it's a high degree of photostability, and is recommended for use in styrenics, vinyls, polycarbonates, polyesters and acrylics. With the normal use level ranging from 0.2 to 0.8%. SONGSORB 3200 is highly effective in stabilizing urethane and nitrocellulose coatings at a use level range of 0.5 to 2.0%, and can be used in combination with phenolic and phosphate antioxidants, as well as HALS, to optimize performance in outdoor applications. Note: Should be stored in a cool, dry, well ventilated are, away from direct sunlight.

          SONGSORB 3260 PW
SONGSORB 3260 is a strong absorber of ultraviolet light in the 300-400nm region and has a high degree of photostability. It has a greater absorption of longer wavelengths than SONGSORB 1000 and better compatibility with polyolefins, lower volatility, and suppressed ionization of the phenolic group. It is less affected by alkalinity, is less likely to discolor with metals, and has less effect on metal driers and metal catalysts due to the higher dissociation constant of SONGSORB 3260. Recommended for use levels of 0.2 - 1.0% in PP, PE, polybutylene, polyesters, and coatings. Can be used in combination with phenolic and phosphate antioxidants and HALS to optimize performance in outdoor use. SONGSORB 3260 is FDA listed in 21 CFR 178.2010, Antioxidants and/or stabilizers for polymers.

          SONGSORB 3270 PW
SONGSORB 3270 is a strong absorber of ultraviolet radiation in the 290-500nm region and has a high degree of photostability (photochemical energy absorbed in the ultraviolet region is dissipated as thermal energy). Exhibits good initial color, low volatility, excellent stability to heat and light, superior wash fastness, and resistance to gas fading. It's particularly suitable for PP and PE, as well as cold cured polyesters, polyurethanes, dyes, and pigments. The low pKa and high hindrance of the phenolic group result in low sensitivity to metal containing ingredients in the polymer formulation (catalysts residues, metallic dries, etc). Can be used in combination with phenolic and phosphate antioxidants, and HALS to optimize performance in outdoor use.

          SONGSORB 3280 PW
SONGSORB 3280 is a strong absorber of ultraviolet light in the 290-400nm region and has a high degree of photostability, featuring strong UV absorption, low initial color, good solubility in plasticizer and monomers, moderately low volatility and excellent compatibility in a wide variety of substrates. Recommended for use in polyolefins, PVC, styrene homo- and co-polymers, ABS, acrylic polymers, unsaturated polyesters, thermoplastic urethanes, moisture-cured polyurethanes, polyacetals, polyvinylbutyral, two component epoxies and urethanes, oil alkyds and thermosetting acrylic enamels. Can be used in combination with phenolic and phosphate antioxidants, and HALS to optimize performance in outdoor use. SONGSORB 3280 is FDA listed in 21 CFR 175.105, Adhesives for food packaging.

          SONGSORB 3290 PW
SONGSORB 3290 is a strong absorber of ultraviolet light in the 200-400nm region and has a high degree of photostability. Provides effective light stabilization and prevents the yellowing and degradation of polymers such as polycarbonate, unsaturated polyesters, and acrylics. Can be used in combination with phenolic and phosphate antioxidants, and HALS to optimize performance in outdoor use. SONGSORB 3290 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.

          SONGSORB 8100 PW
SONGSORB 8100 absorbs ultraviolet radiation in the 240-340nm region. Exhibits synergy with HALS. Excellent solubility and compatibility with high solid coatings formulations. For better long-term performance use of UVAs of the benzotriazole. Can be used for PE, PP, PVC, PS, PC, PP fiber, Ethylene vinyl acetate etc. Provides good light stability effect in Paints, Powder coatings, Polyurethanes, Rubbers. Dosage is 0.1~0.5% based on polymer weight. Is recommended in PE, PP, PVC etc. For additional information please consult the MSDS.
