Abstract
A composition for a flame-retardant silane-crosslinked olefin resin, an insulated wire including the same, and a method for producing a flame-retardant silane-crosslinked olefin resin. The composition contains silane-grafted polyethylene made by graft polymerization of very low-density polyethylene having a density of 0.880 to 0.895 g/cm3 with a silane coupling agent, a polypropylene elastomer, metal hydroxide, and a silane crosslinking catalyst. The method includes the steps of kneading a batch containing silane-grafted polyethylene, a batch containing a polypropylene elastomer and metal hydroxide, and a batch containing an olefin resin and a silane crosslinking catalyst, molding a composition of the kneaded batches, and subjecting the molded composition to water crosslinking.
