(57) [Summary] [Purpose] Providing a window material for hot water level inspection that is free from cloudiness, weathering discoloration, and yellowing during use. [Composition] A hot water level obtained by molding a polyolefin resin composition for the inner layer and the outer layer having two different specific physical properties (MFR, crystal melting point, density) and stabilizer formulation into a two-layer sheet shape. Window material for inspection. [Effect] Compared to the comparative example (single-layer structure), the example shows significantly superior results in terms of hot water resistance, heat resistance, and weather resistance. |
