Stabilizer mixture, used for stabilizing polyurethane for e.g. sheet, shoe sole, roller, fiber, hose, cable, sealant or tire production, contains antioxidant, hindered amine light stabilizer, UV absorber and phosphorus compound

摘要

Stabilizer mixture contains an antioxidant, a HALS (hindered amine light stabilizer) compound, a UV absorber and a phosphorus compound. Independent claims are also included for the following: (1) Polyurethanes containing the stabilizer mixture. (2) Production of stabilized polyurethanes by reacting polyisocyanates with compounds containing at least 2 isocyanate-reactive hydrogen atoms and optionally chain extenders, catalysts and/or additives, in which a phenolic antioxidant, HALS compound, UV absorber and phosphorus compound are added, separately or as a mixture, to at least one of these components or the resultant polyurethane.
