PROBLEM TO BE SOLVED: To provide a rubber composition for water supply piping which can form a rubber component having excellent chlorine resistance, also allowing TOC in tap water to be reduced, and further preventing burning, as compared to the conventional art.SOLUTION: A rubber composition for water supply piping is prepared by blending a rubber content comprising EPDM with sulfur as a crosslinking component for crosslinking the rubber content and a thiazole promoter and/or thiuram promoter with a molecular weight of 250 or more and 600 or less.SELECTED DRAWING: None
【課題】塩素に対する耐性に優れるとともに現状よりも水道水中のＴＯＣを低減しうるゴム部品を形成できる上、現状よりも焼けを生じにくい上水道配管用ゴム組成物を提供する。【解決手段】上水道配管用ゴム組成物は、ＥＰＤＭを含むゴム分に、当該ゴム分を架橋させるための架橋成分として硫黄と、分子量２５０以上、６００以下のチアゾール系促進剤および／またはチウラム系促進剤を配合した。【選択図】なし
