Dual wall co-extruded corrugated tubing

摘要: Dual wall co-extruded corrugated tubing which includes an outer protective layer fabricated from a relatively rigid plastic material, such as polypropylene or nylon, provides crush strength, abrasion resistance, enhanced burst strength and thermal resistance inner sealing softer, more ductile, polymeric thermoplastic elastomer, to provide surface. The dual is preferably integral one-piece component in single operation replaces prior art extruded tubing, having end seals, are attached ends of the length separate operation.
