UV-81 (531)

Technical Datasheet | Supplied by MPI Chemie
UV-81 (531) by MPI Chemie is benzophenone UV absorber. It imparts good light stability when used in combination with a hindered amine light stabilizer such as LS-292 and LS-123. This additive shows good compatibility with polyolefins and plasticized PVC. It protects polymers against degradation caused by light exposure such as rubbers. UV-81 (531) is used for the light stabilization of low density and linear low-density polyethylene & ethylene-vinyl acetate copolymers for agricultural films. Also, used as a UV barrier to protect the contents of industrial and consumer applications. It is used in high density polyethylene molded articles like crates. Recommended for photovoltaic electronic, wire & cable, PE extrusion, building membranes, window & door profiles, pipes & fittings and decking & fencing.
