Unique Low Permeation Elastomeric Laminates for Fuel Hose 960140

The need to meet today's stringent environmental legislation requires that all fuel system components, including flexible rubber hoses, have exceptional permeation resistance to standard and oxygenated fuels.
To help meet this need, new ultra low permeation laminates that retain the flexibility of rubber fuel hose have been developed. These laminates are made up of a fuel contact layer of fluoroelastomer (FKM), a permeation barrier of very thin (0.05 mm) fluorinated ethylene propylene (FEP) plastic film and a conventional elastomeric backing layer. Adhesion between the layers exceeds the tear strength of the elastomers.
These laminates are useful for making fuel hose that exhibits outstanding permeation resistance while retaining the ease of coupling and the flexibility associated with standard rubber hose.
