表1に記載したフルオロポリマーを本発明に用いた。モノマーの組成比は19F−NMRにより決定した。ASTM 1646−00に基づきこの材料のムーニー粘度(ML1+10(121℃))を測定した。結果をムーニー単位(Mooney unit)で記載する。ガラス転移点(Tg)は、昇降温速度(temperature rate)を20℃/分としたときのピークの中間点の温度から得た。示差走査熱量測定法(DSC)により0から200℃まで走査したが、どのポリマー試料にも融解ピークおよび融解点は検出されなかった。
ムーニー粘度はASTM1646−00(ML1+10(121℃))に基づき測定した。結果をムーニー単位で記す。
表1のフルオロエラストマーゴムLTFE−1と各組成物に使用する原料とを標準的な方法を用いて2本ロールミルで配合した。トリアリルイソシアヌレート(TAIC)共架橋剤(活性成分72%のTAIC DLC−Aとして、オハイオ州アクロンのハーウィック(Harwick,Akron,OH)より入手可能)、2,5−ジメチル−2,5−ジ(t−ブチルペルオキシ)−ヘキサン(活性成分50%のバロックス(Varox)DBPH−50として、コネチカット州ノーウォークのアール・ティー・バンダビルト(R.T.Vanderbilt,Norwalk,CT)より入手可能)、酸化亜鉛(ペンシルバニア州モナカ(Monaca,PA)のジンク・コーポレーション・オブ・アメリカ(Zinc Corporation of America)よりUPS−1として入手可能)、およびカーボンブラック(カナダ国アルベルタ州メディシンハットのキャンカーブ・リミテッド(Cancarb Limited,Medicine Hat,Alberta,Canada)よりサーマックス(Thermax)MT,ASTM N990として入手可能)を他の原料と混合した。このゴム状配合物の組成を表2にまとめる。
