- Such a paste processing method is generally widely used because of its ease of processing.
- the paste sol is required to have roughly two performances, that is, the performance as a paste sol and the performance as a molded body after processing it. Specifically, one performance is required to be excellent in workability, that is, appropriate viscosity characteristics (low viscosity), and storage stability as a paste sol, that is, excellent in sedimentation and viscosity stability. The second performance is required to satisfy not only flexibility but also various characteristics such as heat resistance and cold resistance.
- the plasticizer for paste sol greatly affects the basic properties such as heat resistance, cold resistance and flexibility of the resulting molded product, as well as the performance of the paste sol such as sol flow characteristics and viscosity stability. The choice is extremely important.

It was necessary to blend in. As a result, there is a concern that problems may occur in terms of safety and the like, and there is currently no plasticizer having well-balanced characteristics that satisfy all of the above required characteristics alone.

引張特性は、JIS K-6723(1995)に準拠し、プレスシートの100%モジュラス、破断強度、及び破断伸びを測定した。100%モジュラスの値が小さいほど柔軟性が良好であることを示す。破断強度、及び破断伸びは、その材料の実用的な強度の目安であり、一般的にはその値が大きいほど実用的な強度に優れると言うことができる。
耐寒性は、クラッシュベルグ試験機を用いて、JIS K-6773(1999)に準拠して測定した。柔軟温度(℃)が低いほど耐寒性に優れる。ここで言う柔軟温度とは、前記測定において所定のねじり剛性率(3.17×103kg/cm2)を示す低温限界の温度を指す。
耐熱性は、下記揮発減量及びシート着色で評価した。
b)シート着色 :ギヤーオーブン中、上記ロールシートを170℃で表中に記載の時間加熱した後のそれぞれの着色度の強弱を目視により6段階で評価した。
○:僅かに着色
○△:少し着色
△:着色
×:強い着色
××:著しい着色
(11)耐フォギング性

100%モジュラス残率(%)=(1-(加熱後の100%モジュラス―加熱前の100%モジュラス)/加熱前の100%モジュラス))×100
伸び残率(%)=(加熱後の破断伸び/加熱前の破断伸び)×100
(13)紫外線照射試験
紫外線照射試験は、ダイプラ・ウィンテス社製メタルウェザー超促進耐候性試験機を用いて、測定条件(照射エネルギー:100mW/m2、照射条件:ブラックパネル温度53℃/湿度50%/4時間、結露条件:ブラックパネル温度30℃/湿度98%/2時間、シャワー条件:結露前後10秒)を1サイクルとして、5サイクル実施した後のプレスシートの着色度の強弱を目視により4段階で評価した。
