Two new hindered amine light stabilizers (HALS) and a uv absorber are the latest additions to the Uvinul line of stabilizers from BASF Corp., Performance Chemicals, Florham Park, N.J. Uvinul 5062 H is an oligomeric HALS that boasts excellent performance in polyolefins such as PP copolymers and TPOs. Uvinul 4092 H is a liquid monomeric HALS that is reportedly well suited to polyurethane, PVC, and liquid colorants for PET. Uvinul 3034 is a benzotriazole uv absorber said to be very effective in PET, PC, and nylon, due to its low volatility and excellent heat resistance. Both 3034 and 5062 H have been approved by the FDA and the EU for use in food-contact applications.
