65RH%の状態で6週間貯蔵後の加硫・発泡成形も良好に行うことができることが認められた。
発泡ゴム組成物のムーニースコーチタイムは、JIS K6300−1に基づいて、温度125℃において、粘度が最低値から、最低値と最高値の差の5%増加するまでの時間(分)を測定した。
発泡ゴム組成物を押出機にて、温度54℃で厚み9mmになるように押出成形し未加硫ゴムシートを得た。未加硫ゴムシートを所定の長さに切断して、厚み12mm(発泡代3mm)の額縁状金型枠の中に入れ、温度150℃、圧力1.2MPaの条件で1時間、加硫発泡成形を行い、発泡倍率25%の発泡ゴム成形体を得た。得られた発泡ゴム成形体をJIS K 6253に準じて、JIS−A硬度を測定した。
