Abstract
【解決手段】 テトラフルオロエチレンとパーフルオロ(アルキルビニルエーテル)との共重合体(A)、テトラフルオロエチレンの重合によって直接得られた溶融流動性のポリテトラフルオロエチレン(B)及び非溶融流動性高分子量ポリテトラフルオロエチレンの放射線分解によって得られた低分子量ポリテトラフルオロエチレン(C)からなり、A/(B+C)の重量比が80/20〜30/70であり、(A+B)/Cの重量比が99.99/0.01〜90/10であることを特徴とする溶融成形用フッ素樹脂組成物が提供される。
Description
(1/組成物のMFR)1/3.4=(PFA(A)の重量分率)(1/PFA(A)のMFR)1/3.4
+(PTFE(B)の重量分率)(1/PTFE(B)のMFR)1/3.4
+(PTFE(C)の重量分率)(1/PTFE(C)のMFR)1/3.4
但し、組成物のMFRは混合中のポリマーの熱分解やカップリング現像、あるいは混合後のフッ素化等の後処理により、上記関係式により求められる数値から若干外れる場合があるので、PFA(A)、PTFE(B)及びPTFE(C)のMFRはこの変動をも考慮し、最終組成物のMFRが希望の範囲に入るよう決定することができる。
PAVE含有量:試料を350℃で圧縮した後水冷して得られた厚さ約50ミクロンのフィルムの赤外吸収スペクトル(窒素雰囲気)から、米国特許第5760151号記載の方法に従い求めた。
メルトフローレート(MFR):ASTM D1238−95に準拠した耐食性のシリンダー、ダイ、ピストンを備えたメルトインデクサー(東洋精機製)を使用し、5gの試料を372±1℃に保持されたシリンダーに充填して5分間保持した後、5kgの荷重(ピストン及び重り)下でダイオリフィスを通して押し出し、この時の溶融物の押し出し速度(g/10分)をMFRとして求めた。
窒素ガス透過度:350℃で溶融圧縮成型によって作成された厚さ0.25−0.35mmのフィルムについて、柴田化学機械製S−69型ガス・水蒸気透過度測定装置を使用し、温度23℃で測定した。
この試験を30日継続した時の総塩酸透過量を表3に示す。
