Abstract (en)
[origin: WO9419638A1] Our development provides a hose (10) suitable for use in transporting refrigerants. The hose has an inner tube (20) with improved flexibility while maintaining low gas permeability without the use of extractable plasticizers. The inner tube includes an inner wall (21) and a rubbery outer wall (22), wherein the inner wall is nylon and a non-extractable elastomeric plasticizer, and the rubbery outer wall is a butyl rubber. The hose also has an outer wall (40) made of a rubber such as chlorinated butyl rubber.
