Description
アクリロニトリルブタジエン系ゴム(NBR、HNBR)は耐油性が優れることからとくに油性製剤に使用されるが、日本薬局方第16改正輸液用ゴム栓試験では他のポリマーと比較して溶出物が多くなる。この原因はNBR、HNBR重合時に添加される乳化剤、凝固剤等の残液による。そこで、接液側にアクリロニトリルブタジエン系ゴムを使用し、ブチルゴムと積層することで、耐油性に優れ、輸液用ゴム栓試験に適合するゴム栓が得られる。
エチレンプロピレン共重合(EPR)ゴムは高pH製剤に使用することができるものの、針刺し時の復元性が劣る。そこで、接液側にエチレンプロピレン共重合ゴムを使用し、ブチルゴムと積層することでこれらの問題が解消する。

表1に示す配合で、非接液部の未加硫ブチルゴムシート1.21mmと接液部のニトリルゴムシート1.5mmの間に厚さ100μmの超高分子量ポリエチレンフィルムを挿んで、170℃/10分、真空プレスで一段成形し、5mlバイアル用ゴム栓を作製した。
未加硫ゴムシートの比重は、自動比重計(水中置換式密度・比重計)(株式会社東洋精機製作所製)を用いて測定した。
未加硫ゴムシートの色差は、色差計(CR−221、株式会社ミノルタ製)を用いてNBS単位で3回測定し、その平均値を色差値とした。
JIS K6256−1に準拠し、50mm/分の条件で測定した。
医療用ゴム部品の溶出物試験は、JP16輸液用ゴム栓試験に準拠して行った。試験項目と規格値を以下に示す。
性状 :無色透明
UV透過率 :波長430nmと650nmでともに透過率99.0%以上
UV吸収スペクトル :波長220〜350mmで吸光度0.2以下
泡立ち :3分以内に消失
pH :±1.0以内
亜鉛 :lμg/mL以下
KMmO4還元性物質 :2.0mL/100mL以下
蒸発残留物 :2mg以下
それぞれの成形シートの状態で非接液部側のブチルゴムが接液部に現出(侵入)している成形不良品をマーキングしておき、打抜き、洗浄乾燥処理乾燥後、マーキングした成形不良品を取出した。次に、良品内に成形不良品を各10個混入させて500個とし、3名により目視検査によって検出率を求めた。
表1に示す配合で、未加硫ゴムシートを作製した。未加硫ゴムシート2.5mmを用いて170℃/10分、真空プレスで成形し、5mlバイアル用ゴム栓を作製した。2層ゴム栓ではないため、2層ゴム栓のような不良品は存在しない。
