Title:
POLYAMIDE COMPOSITE RESIN AND REFRIGERANT TRANSPORT HOSE
Document Type and Number:
WIPO Patent Application WO/2005/097903
Kind Code:
A1
Abstract:
Disclosed is a polyamide composite resin having excellent bas barrier properties as well as sufficiently excellent flexibility and durability which is capable of forming a good gas-barrier layer for refrigerant transport hoses without having a multilayer structure. Also disclosed is a refrigerant transport hose which is easily produced using such a polyamide composite resin. Specifically disclosed is a polyamide composite resin containing a polyamide and a polyolefin, wherein the polyamide includes a metaxylenediamine as a constitutional unit. The polyamide composite resin, which is a polymer alloy wherein a polyolefin is added as a flexibility-imparting agent, is excellent in bas barrier properties, flexibility and durability. A refrigerant transport hose has the innermost layer composed of such a polyamide composite resin.
