Description
In standard extrusion, solid plastic pellets are gravity fed into a forming mechanism, where jacketed compression screws melt and feed the materials into a die. By contrast, coextrusion involves multiple extruders forming layered or encapsulated parts. Sometimes five or more materials are used in a single cycle, with each extruder delivering the precise amount of molten plastic needed for the operation.
Unlike ordinary plastic mixing, each individual plastic retains its original properties, but is combined into a compound-material part. If mixed prior to extrusion, the characteristics of the individual materials may be altered, but the end result is a homogeneous product.
Not all plastics are suitable for coextrusion because some polymers will not adhere to others, although introducing a conductive middle layer can often solve this problem. Plastics with drastically different melting temperatures are also unsuitable for the process, as degradation will occur in the lower melting material. Finally, PVC and acetals should never be coextruded together because of the potentially violent reactions that can occur when they are joined.
Co extrusion profiles can use many different materials, according the product features to adopt appropriate materials. So it is widely used for automotive, appliances, furnishings, construction, toys.

JF Representative co-extrusion products
The co-extrusion process combines two or more different materials in a single extrusion process. Two or more extruders deliver the desired plastics to a single extrusion head, or die, to manufacture the part. The materials can be combined or layered, using different compounds for the layers. Preferred Plastics’ co-extrusion capabilities include:
Dual hardness profiles using multiple resins
Simple and complex shapes, manufactured to industry standard
Small and large shapes
Wide range of thermoplastic materials, including PVC, ABS, TPU, and TPE.
The multi-colored drinking straw is a good example of coextruded tubing’s design features. Striped tubing also serves many purposes in the medical field, in which stripes and colors can denote different chemicals. Coextrusion can produce internally hardened tubes through which a cable can be run while retaining the tube’s flexibility. Other tubes benefit from a high performance liner impervious to corrosives, or an inexpensive coating to add bulk and stability. In addition, plastic fiber optic cables are composed of a coextruded cable and jacket.
