Coextrusion Plastic Profiles & Tubing
Industrial applications for Coextruded Plastic Profiles and Tubing
Coextruded, plastic profiles and tubing are found in a wide variety of industries: building and construction; consumer packaging; electrical; automotive; food processing; and medical devices to name a few. Plastic tubing is everywhere.
Coextrusion has opened new frontiers in material engineering and addresses previously difficult manufacturing and processing needs. For example, a coextruded tube could have an internal hardened tube through which a cable can be run along with a flexible outer layer to maintain maneuverability. Other applications benefit from a high performance liner impervious to corrosives, or an inexpensive coating to add bulk and stability.
In the construction and home improvement industries, coextruded plastic parts expand options and reduce cost and bulk. For example, weather stripping for doors and windows require a combination of a rigid and flexible material for peak performance. Coextrusion can provide a single profile with these contradictory properties. Coextrusion can also reduce costs by using recycled and reground scrap inside virgin material for handrails, fences and other applications.
GLOSSARY: The extrusion of multiple layers of distinct materials simultaneously into a desired form.
