上記ペレットを用いて試験片を成形し、曲げ試験(ASTM D790準拠)を実施した。曲げ弾性率、曲げ歪みを表3に示した。
上記ペレットを用いて、外径Φ29mm×内径Φ24mm(肉厚2.5mm)×幅1.6mmのシールリングを射出成形により製造した。図4に示すように、このシールリング21をテーパー治具19へ速度1mm/sで挿入し、破損したときの内径寸法(=限界拡張量)を測定した。用いたシールリングおよびテーパー治具の詳細な寸法は、図5に示すとおりである。試験結果を表4に示した。
得られたシールリングの特性について、図6に示す試験機により、シールリングの耐久試験を行なった。図6は試験機の概略図である。この試験機は、モータ18、カップリング16、回転トルク計15、試験ヘッド17から構成される。試験ヘッド17において、相手軸12の環状溝にシールリング11を2つ装着した。シールリング11は、相手軸12の環状溝の側壁と、ハウジング13の軸孔内周面と摺接する態様としてある。装置右側より、油を圧送して、2つのシールリング11の間の環状隙間に供給した。14は油温用の温度計である。詳細な試験条件は、下記表5に示すとおりである。なお、シールリングとしては、外径Φ29mm×内径Φ24mm(肉厚2.5mm)×幅1.6mmのシールリング(図5(a)参照)を用いた。
