A system and method are presented in which a flow of plastic is extruded to obtain nano-sized features by forming multiple laminated flow streams, flowing in parallel through the non-rotating extrusion system. Each of the parallel laminated flow streams are subjected to repeated steps in which the flows are compressed, divided, and overlapped to amplify the number of laminations. The parallel amplified laminated flows are rejoined to form a combined laminated output with nano-sized features. The die exit is formed to provide a tubular shape.

A multi-striped electrical cable may be provided. The multi-striped electrical cable may comprise a conductor, an inner layer, an outer layer, and a stripe. The conductor core may comprise a conductor. The inner layer may be around the conductor core and may comprise an inner layer polymer. The outer layer may be around the inner layer. The outer layer may comprise an outer layer polymer, an outer layer colorant, and an outer layer friction reducing additive. The stripe may be disposed on an outermost portion of the outer layer. The stripe may comprise a stripe polymer, a stripe colorant, and a stripe friction reducing additive.
