曲げ角度測定のための試験方法:
曲げ角度の測定のために、適当なポリウレタン製の成形物(長さ:110mm;幅:25mm;高さ:2mm)を末端で180℃折り曲げ、厚みが4mmの鋼板二枚の間に挟み、90℃のオーブン中で16時間保存した。次いでこの成形物をオーブンから取り出し、15分間後に室温でその直線からのずれを測定した。測定された曲げ角度が小さいほど、その材料は良好である。
測定に用いるイソシアネート含有材料を、まずジクロロメタン中に溶解させる。想定されるNCO含量に応じて試料の重量を決める必要がある。約50mg(NCO含量が約30〜40%の場合)〜500mg(NCO含量が約1〜2%の場合)の範囲の量を正確に評量して10mLの容量フラスコに入れ、約8mLのジクロロメタンと混合し、完全に溶解するまで振とうする。次いでこのフラスコにジクロロメタンを校正マークのところまで加える。
