It is a thing. In heat resistance B, 150 ° CX Cross-linked PV without cracking for 42 days or more Excellent heat resistance in the presence of c. On the other hand, in Comparative Example 9 having the same composition, except that the aluminum hydroxide was replaced with the surface silane-treated magnesium hydroxide, cracking occurred at 150 ° C. X 21 days.
- the non-halogen electric wire of the present invention has little decrease in life even when the coating material comes into contact with a member containing PVC resin. Therefore, even if this non-halogen wire is mixed with a wire containing PVC resin to form a wire bundle, or a wire bundle is formed using a binding material containing PVC resin, etc., There is little deterioration. Since the electric wire bundle of the present invention has such excellent characteristics, the wire harness for automobiles having the electric wire bundle force has little generation of halogen-based gas at the time of incineration or the like, and there is no decrease in its life. It has excellent characteristics. Although thermal degradation caused by contact with a member containing PVC resin cannot be reduced by adding an antioxidant or the like, the present invention reduces this thermal deterioration without increasing the amount of antioxidant. An effect is obtained.
