发明名称 冷媒輸送用ホース及びそのガスバリア層形成用ポリアミド樹脂組成物
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a refrigerant transportation hose having a gas barrier layer that consists of a polyamide resin composition, which is excellent in durability since the gas barrier layer is prevented from deteriorating due to an acidic component and moisture issuing from a refrigerant and a compressor oil. <P>SOLUTION: The refrigerant transportation hose 1 has the gas barrier layer 2 that consists of the polyamide resin composition. The polyamide resin composition contains 1-20 pts.wt. of a silica-base inorganic substance based on 100 pts.wt. of a polymer component in the polyamide resin composition. An olefinic elastomer may be blended into the polyamide resin composition to improve flexibility and durability. <P>COPYRIGHT: (C)2012,JPO&INPIT</p>
