Abstract
Description
下記の表1に記載のように、本実施例においては、PTFE固形成分含有量が30.0重量%から60.0重量%、PTFE粒子の大きさが0.1ミクロンから6.0ミクロンであるPTFE水性分散液を用意した。
この実施例では、3種類の市販のPTFE分散液に高分子種を添加した場合の安定性を評価した。各サンプル試験において、約25.0 gの市販のPTFE水性分散液を30.0固形分重量%程度にまで蒸留水で希釈し、3インチガラス容器に室温で添加した。安定化させていない分散液の典型として、旭硝子フロロポリマーズUSAのAD058を使用した。このPTFE分散液は約30.0重量%のPTFE粒子を含んでおり、その平均粒径は約0.21から0.33ミクロンであるが、少量の(1.0重量%未満)APFOを除き、一般的な界面活性剤を含有していない。
表2
この実施例では、各サンプル試験において、PTFE分散液に高分子種を添加したあと分散液を冷凍庫で一晩凍結させたという点を除き、手順は上記実施例2と同じである。凍結させた分散液はそのあと解凍し、1、3、7日間放置したあと、形成された水相の高さを上述のように測定した。結果は下の表3のとおりである。
