Description
(1)熱可塑性ポリウレタンエラストマー
TPU(1):日本ポリウレタン工業(株)製ミラクトランE180(アジペートタイプ、比重1.21、ショアA硬度80、ガラス転移点−45℃)
TPU(2):日本ポリウレタン工業(株)製ミラクトランE380(エーテルタイプ、比重1.11、ショアA硬度80、ガラス転移点−61℃)
(2)エチレン・(メタ)アクリル酸共重合体
EMAA:エチレン・メタクリル酸共重合体(メタクリル酸含量10重量%、メルトフローレート(190℃、2160g荷重)35g/10分)
(3)エチレン・酢酸ビニル共重合体
EVA:酢酸ビニル含量25重量%、メルトフローレート(190℃、2160g荷重)2g/10分)
(4)メタロセン直鎖状低密度ポリエチレン
m−LLDPE:三井化学(株)製エボリューSP3040(メルトフローレート(190℃、2160g荷重)3.8g/10分、密度928kg/m3)

JIS K7199に準拠し、キャピラリーレオメーター(東洋精機(株)製、L/D=33.4)を用い、試験温度200℃及び220℃、ピストン速度0.5mm/分における見掛け粘度を測定して評価した。
(イ)バブル安定性
インフレーションフィルム作成時のバブル状態を、目視により次の基準で評価した。
○:バブルは常時安定している
△:バブル形状に変動が見られ、安定しない
×:バブル形成が不可能
インフレーションフィルム作成時のフィルム口開きを、手剥離により評価した。
○:容易に口開きが可能である
△:治具(粘着テープ等)を使用すれば、口開きは可能である
×:口開きは不可能である
2mm厚みに打ち抜いたプレスシートを用い、JIS K6760に準拠し、引張速度500m/分にて、100%モジュラス、200%モジュラス、300%モジュラス及び破断点伸度(%)を測定した。
上記インフレーションフィルム成形条件にて作成した200μmフィルムを用いて、試料幅:20mm、長さ:60mmの試料片を作成し、長さ方向に50%伸張(60→90mm)して両端を固定し、25℃、50%RH環境下で2日間放置後、開放して1時間後のフィルム長さをLmmとしたとき、回復率を次の式で計算し、下記する3段階で評価した。
回復率(%)=100−((L−60)/60×100)
○:回復率80%以上、 △:70%以上80%未満、 ×:70%未満
表1に示す配合割合で熱可塑性ポリウレタンエラストマーTPU(1)又はTPU(2)とエチレン・メタクリル酸共重合体EMAA(実施例1〜6)、EVA(比較例3)又はm−LLDPE(比較例4)を上述した方法でメルトブレンドし、その物性を上記方法にしたがって評価した。同様に熱可塑性ポリウレタンエラストマーTPU(1)又はTPU(2)についても同様の評価を行なった(比較例1〜2)。その結果を表1に示す。
