Title:
FLEXIBLE IMPERMEABLE FILM AND IMPERMEABLE HOSE
Document Type and Number:
Japanese Patent JP2002174369
Kind Code:
A
Abstract:
To realize, in a hose with high fluid impermeability imparted by use of a metallic thin film, the fatigue durability of the metallic thin film resistible to engine vibration or the impulse pressurization of a coolant hose while keeping the flexibility of hose.
A flexible impermeable film formed by covering both sides of the metallic thin film with a thin film of resin showing a stress at yield of 70 MPa or more at the using temperature of the hose is integrated to the hose repeatedly deformed at a distortion quantity of 5% or less as a fluid impermeable layer.
