Custom Plastic Coextrusions

When one material just won’t cut it, due to flexibility, durability, or resistance issues, coextrusion provides the solution. By combining two or more materials into a single profile or tube, our coextrusion process gives you the best of both worlds: multiple material properties, one streamlined part.

What Is Coextrusion?

Coextrusion is the process of simultaneously extruding multiple layers of thermoplastic through a single die head. Each material is fed through its own extruder, allowing us to fine-tune the thickness, structure, and function of each layer independently.

That means you get a finished product where every layer performs exactly as needed, no post-processing, no workarounds, and no compromising on material choice.

Why Choose Coextrusion Over Single Extrusion?

• Combine rigidity with flexibility
• Add UV, chemical, or moisture resistance where it counts
• Reduce costs by using specialty materials only where needed
• Create multi-function profiles with fewer assembly steps

Materials That Match Your Performance Needs

Choosing the right materials is crucial in coextrusion, particularly when different parts of your profile require distinct functions. We work with a wide range of thermoplastics to ensure each layer delivers exactly what your application requires, whether it’s strength, flexibility, clarity, or resistance.

• Polyethylene, low and high-density
• Acrylic / Noryl
• Polypropylene (different variations of polymer)
• ABS
• PVC
• TPR

Are you unsure which combination works best for your product? We’ll help you select the right materials to maximize performance without overengineering.

Plastic Extrusion Applications

We engineer custom profiles that resist corrosion, maintain structural integrity, and meet the demands of real-world environments.

We serve a wide range of industries and use cases, including:

• Brush products: Durable backing and structural components for industrial and commercial brushes
• Refrigeration: Custom seals and profiles designed for thermal insulation and moisture control
