硬化レオロジー
177℃、プレヒートなし、経過時間30分および0.5弧度の条件でASTM D5289−93aに準拠して、Monsanto Moving Die Rheometer(MDR)Model2000を用いて未硬化の配合サンプルについて試験を行った。平坦域もしくは最大トルクが得られなかった時に規定時間中に達成された最小トルク(ML)と最高トルク(MH)の両方を測定した。トルクがMLより2単位増加する時間(「ts2」)、トルクがML+0.5(MH−ML)に等しい値に達する時間(「t’50」)およびトルクがML+0.9(MH−ML)に達する時間(「t’90」)も測定した。
特に注記がない限り、177℃で30分間にわたり約6.9メガパスカル(MPa)でプレスすることにより、150x150x2.0mmの寸法のサンプルシートを、物理的特性決定のために作製した。
次の6段階の条件:6時間にわたり25〜200℃、16時間にわたり200℃、2時間にわたり200〜250℃、8時間にわたり250℃、2時間にわたり250〜300℃、16時間にわたり300℃、を用いて、プレス硬化したサンプルシートを窒素下で熱に曝した。試験前に、サンプルを室温に戻した。
プレス硬化および後硬化したサンプルシートを290℃で70時間にわたり空気中で熱にさらし、その後、試験前に室温に戻した。
ASTM Die Dによりプレス硬化または後硬化したシートから切断したサンプルについて、ASTM D412−92を用いて破断点引張強度、破断点伸び、および100%伸び時の弾性率を決定した。単位はMPaで報告する。
タイプA−2ショアデュロメータ(durometer)によりASTM D2240−85方法Aを用いてサンプルを測定した。単位はポイントで報告する。
