Description
図1は、本発明の実施形態による多層樹脂チューブの横断面を示す。この多層樹脂チューブは、外側から順に第1層から第6層まで全部で6層の樹脂層から構成されている。第1層は、チューブの強度を保持し、低温での耐衝撃性を高めるための樹脂層である。第2層は、樹脂チューブに低透過性を付加するための第1の低透過性バリア層である。第5層は第2の低透過性バリア層、第6層は第3の低透過性バリア層であり、この実施形態では、低透過性バリア層が合計3層設けられている。第3層は、第2層と第5層との接着性を補強するためのスペーサ層である。第4層は本来の接着強度を保持する接着材料からなる接着層である。
第3層に用いるPA11、PA12は第1層と同様である。
第4層の接着層に用いられる樹脂は、接着性樹脂アミド結合またはイミド結合を可能となるアミド基またはイミド基をもつ樹脂や、カルボン酸や酸変性された樹脂があり、好適なものとしては、例えば、宇部興産製7034Uがある。
第6層をETFEで構成した例が実施例9、10である。
