Composite structure of the typical four plastic hose :

    1, polyethylene (outer) / adhesive resin (white) / ethylene vinyl alcohol / adhesive resin / polyethylene (inner).

    2, polyethylene (outer) / adhesive resin (white) / polyester (or SiO. A12O3 other coatings) / adhesive resin A1203/ polyethylene (inner).

    3, polyethylene / adhesive resin (white) / polyester / adhesive resin.

    4, polyethylene / adhesive resin / ethylene vinyl alcohol / adhesive resin / polyethylene.

    Co-extruded composite hose with a hose linking the contrast and multi-layer co-extruded composite flexible hose compared with the more advantages, But with the development of multi-layer coextrusion technology, which it will be some changes.
