Abstract

　環境への影響を配慮しつつ優れた難燃性を有するとともに、低温から高温まで広い温度範囲にわたってアンテナ材料として十分な誘電特性を有する誘電性エラストマー組成物、および、該組成物を成形してなるアンテナ用部材を提供する。エチレンプロピレンゴム等のエラストマー 100 重量部に対して、水酸化アルミニウム粉末、水酸化マグネシウム粉末等の金属水酸化物を 100～600 重量部配合してなる誘電性エラストマー組成物であって、周波数 400 MHz および温度 30°Cにおいて、この組成物の比誘電率が 3 以上、誘電正接が 0.02 以下であり、さらに、－10°C～70°Cの温度範囲内の任意温度における比誘電率が、30°Cを基準とする比誘電率の±0.4 以内の値である。アンテナ用部材は、この誘電性エラストマー組成物を成形してなる。
