TUBULAR POLYMERIC COMPOSITES FOR TUBING AND HOSE CONSTRUCTIONS

摘要

Multi-layer tubular polymeric composite for articles such as tub ing and hoses. The composite may be formed of an innermost and an outermost layer, and at least one interlayer between the innermost and the outermost layer. The innermost and the outermost layer each may be bonded directly to one of the interlayers, and may be formed of a thermoplastic polymeric material which may be a polyamide. Each of the interlayers may be formed of a thermoplastic polymeric material which may be a polyester or copolyester, or a polyurethane.
