Try to provide. SOLUTION: As a synthetic resin, a composition in which a metallocene-catalyzed polyethylene is used as a main material, and a specific ultraviolet absorber, a radical chain inhibitor, and a peroxide decomposing agent are added thereto in a specific ratio. And a metal pipe is coated with this composition to form a structural material. |
