Abstract:
A thermoplastic polyurethane resin composition comprising: a thermoplastic polyurethane resin; an ultraviolet absorber package comprising a benzotriazole compound (UVA1), and a triazine compound (UVA2) wherein the mass ratio of UVA1 to UVA2 is from 1:1 to 3:1; optionally, a hindered amine light stabilizer and/or an antioxidant compound; and wherein the thermoplastic polyurethane resin composition has a maximum ultraviolet transmittance of ≤3% in the wavelengths between 280 nm and 365 nm and an ultraviolet transmittance of ≤6% in the wavelengths between 365 nm and 370 nm when the thermoplastic polyurethane resin is formed into a film having a thickness of 6 mils and wherein the cumulative weight % of UVA1 and UVA2 in the polyurethane resin composition ranges from 0.5 wt % to 0.85 wt % based on the total weight of the polyurethane resin composition.
