Custom Plastic Coextrusions
While a “traditional” plastic extrusion is made using a single thermoplastic material, a plastic coextrusion is one that is made using two (or more) different materials. Thermoplastic coextrusion is useful when the desired performance or characteristics for a part cannot be achieved through a monolayer or single material plastic extrusion. For example, coextrusions may provide increased strength, greater wear resistance or stiffness, and other beneficial properties that a single material cannot. Other unique features that can be created via plastic coextrusion are outlined below.
In thermoplastic coextrusion, two or more extruders (extrusion machines) feed the required materials into a single die to create a one-piece profile extrusion. Materials may be combined or layered, depending on application and performance requirements.
Crescent Plastics’ Coextrusion Capabilities
Crescent Plastics has extensive experience and expertise in creating custom plastic coextrusions, and can provide coextruded plastic profiles with multiple similar or dissimilar materials that are bonded together into a single, seamless piece.
Our coextrusion capabilities open up a wide range of possibilities for customized plastic extrusion. While every project is different, some of the more common thermoplastic coextrusions we produce include:
- Layered clear and opaque materials
- Different colored materials
- Rigid and flexible materials
- A thin capstock over a thicker substrate
- Flexible “living hinges” that join two rigid materials
- and more
