PURPOSE:To provide a method for producing a polyolefin cross-linked foamed product having an excellent tensile strength, especially an excellent tensile strength at a forming temperature when subjected to a secondary processing such as thermal forming, substantially without deteriorating the mechanical characteristics and heat resistance of the polyolefin resin. CONSTITUTION:A molded product of a composition comprising a polyolefin resin, a foaming agent and cross-linking reaction-accelerating agents consisting of two kinds of a trifunctional compound and a difunctional compound in a specific ratio is cross-linked with ionizing radiations and subsequently foamed. |
