EVA (hereinafter referred to as EVA) has excellent electrical insulation properties, and various physical properties can be improved by appropriately adopting various crosslinking methods such as radiation crosslinking, organic peroxide crosslinking, and silane crosslinking using silane compounds. Due to its merits, it has been widely used in various fields including electrical insulation materials. However, even though EVA has these advantages, when compared to rubber, it lacks flexibility and is too hard. This difficulty becomes a particular problem when this EVA is used as a covering material for insulated wires such as lead wires.

We have been conducting intensive research to develop EVA compositions that can provide crosslinked products with excellent flexibility. It has been found that the intended purpose is achieved when incorporated into EVA. In addition, in this study, it was found that if a specific amount of EPM was blended into the composition of the present invention containing EVA and the above-mentioned specific tertiary carbon atom-containing polymer, more preferable flexibility could be obtained, and this problem had not been solved in the past. The present invention was completed based on these new facts. Parts by weight and tertiary carbon polymers 1-
