Abstract
A hose of improved impulse life is described including an inner polymeric tube which has a relatively hard outer surface, a tightly packed wire reinforcement e.g., braid or spiral, telescoped over the tube, and an expanded polymeric cushion matrix encapsulating at least a portion of the strands of the reinforcement and also promoting wire-to-wire and tube-to-wire adhesion. A method for producing the hose employing a foamable material applicator is also disclosed.
