Description
実施例1〜8および比較例1〜13は、表1に示す成分を示された重量で混合し、二軸押出機により260℃で混練し、ペレット状の樹脂組成物を得た。
得られた樹脂組成物を120℃、10時間真空乾燥した。次に、直径1.3mmの錫めっき軟銅線の周囲に0.3mmの被覆厚で押出成形した。押出成形には、直径がそれぞれ4.2mm、2.0mmのダイス、ニップルを使用し、押出温度はシリンダ部を230℃〜260℃とし、ヘッド部を260℃とした。線速は5m/分とした。
引張伸びは、電線の芯線を引き抜いて作製したチューブ状の試験片を用いて、引張速度200mm/minにて測定を実施した。引張試験はJIS C 3005に従うものとする。
伸び残率(%)は、70%以上のもの及び引張伸度(熱老化後の引張伸び)が200%以上のものを○(合格)とし、伸び残率70%未満のもの若しくは引張伸度(熱老化後の引張伸び)が200%未満を×(不合格)とした。
作製した電線を、150℃の恒温槽で100時間加熱し、室温で12時間程度放置し、引張試験を実施した。熱処理は、JIS C 3005 WL1に従うものとする。
