RIASORB® UV-4050

C₂₆H₅₀N₄O₂

• RIASORB® UV-4050 is a low molecular weight hindered amine light stabilizer (HALS) for applications demanding particularly high light stability. It provides excellent light stability for thick sections but can also be used for articles with a high surface area such as films and tapes.
• RIASORB® UV-4050 is recommended to be used in polystyrene, impact polystyrene, ABS, SAN, ASA, polypropylene, impact modified PP (TPO), EPDM, and in polyamides. Due to its low volatility, RIASORB® UV-4050 is unique for high temperature processes compared to other low molecular weight HALS.
• A special benefit of using RIASORB® UV-4050 is the high light-stabilizing performance, particularly for styrenic polymers and PP to protect the surface. It has broad compatibility and can be easily dispersed.
• RIASORB® UV-4050 can be used in plastic articles in contact with food. The low molecular weight of RIASORB® UV-4050 is not dependent on the polymer’s thickness, so RIASORB® UV-4050 also provides good light stability in articles with a higher specific surface, e. g. films and tapes. RIASORB® UV-4050 can be used alone or combined with high molecular weight HALS, the recommended dosage is 0.1-0.5% depending on the substrate, processing conditions and application.
