Applications

• RIASORB® UV-312 is a highly effective light stabilizer for a variety of plastics and other organic substrates including unsaturated polyesters, PVC and PVC plastisol. It is particularly recommended for rigid and flexible PVC and polyesters. RIASORB® UV-312 exhibits strong absorbance in the 250~350 nm region and no absorption in the visible region (>400nm). RIASORB® UV-312 features strong UV absorption, excellent compatibility in a wide variety of substrates, and low volatility.
• RIASORB® UV-312 protects polymers as well as organic pigments from UV radiation, helping to preserve the original appearance and physical integrity of molded articles, films, sheets, and fibers during outdoor weathering.
