UV-1 (MPI Chemie)

Technical Datasheet | Supplied by MPI Chemie
UV-1 by MPI Chemie is a liquid formamidine UV absorber. It is highly effective for the light stabilization of PUR. It is used in elastomers (spray, RIM), microcellular foams, integral skin foams for footwear and conventional rigid & flexible foams. It is added to PUR systems as a solution in the polyol component (polyether or polyester-based). UV-1 dissipates the absorbed light energy from UV rays as heat by reversible intramolecular proton transfer. This reduces the absorption of UV rays by the polymer matrix and hence reduces the rate of weathering.
