Custom PU Extruded Profiles & Non-Standard Tubing
High-resilience polyurethane extrusion products engineered for custom industrial applications requiring precision, durability, and long-term color stability.
Precision-Engineered Polyurethane Extrusions for Complex Applications
When standard tubes and profiles don’t fit your design requirements, we deliver custom-shaped solutions.
- Unlimited Profile Geometries – from simple ovals to complex multi-cavity designs
- Tight Dimensional Tolerance (±0.12mm)
- Superior Color Stability – no yellowing or fading
- High-Resilience Polyurethane for exceptional durability
- SGS/ROHS Certified for global compliance
When Standard Round Tubes Simply Won't Work
Is your design constrained by the limitations of standard circular tubing? Many advanced applications require non-circular cross-sections to:
- Maximize sealing surface area in limited spaces
- Prevent rotation in guide channels or tracks
- Match specific mounting profiles in equipment housings
- Optimize flow characteristics for unique fluid dynamics
- Integrate multiple channels in a single extrusion (e.g., air + electrical conduit)
- Achieve aesthetic design requirements for visible components
Our custom PU extrusion capabilities transform your engineering challenges into manufactured reality.
Understanding Custom Profile Extrusions
PU Extruded Profiles (also called profiled strips, shaped extrusions, or non-standard tubes) are polyurethane components manufactured with custom cross-sectional geometries rather than standard circular shapes.
Common profile types include:
- D-profiles & P-profiles – for edge sealing and door/window applications
- Rectangular/Square tubes – for structural frames and guides
- Oval & elliptical tubes – for low-profile routing in tight spaces
- Multi-lumen tubes – multiple parallel channels in one extrusion
- Custom shapes – keyholes, triangles, trapezoids, or proprietary geometries
- Co-extruded profiles – combining different materials or hardnesses in one part
The only limit is your imagination – if you can draw it, we can extrude it.
Precision Extrusion Technology
Advanced Extrusion Tooling
We design and manufacture custom extrusion dies in-house, allowing us to create virtually any cross-sectional profile with precision and repeatability.
On-Line Dimension Control (±0.12mm)
Our extrusion lines are equipped with laser-based dimensional monitoring systems that continuously measure and adjust the profile geometry in real-time, ensuring consistent tolerances of ±0.12mm across the entire production run.
High-Resilience Polyurethane Formulation
We use premium, high-rebound polyurethane elastomers that provide exceptional physical properties: superior tear resistance, abrasion resistance, and elastic recovery even after repeated compression or flexing.
Superior Color Stability (Grade 3+ Yellowing Resistance)
Our proprietary UV-stabilized formulations prevent yellowing and color fading, even under prolonged exposure to sunlight or industrial lighting. This is critical for visible components or outdoor applications.
Imported Weather-Resistant Pigments
We use only high-grade, imported color pigments that deliver vibrant, consistent colors that won’t fade, bleed, or discolor over time.

Guarantee and After-sales Service
Custom Multi-Lumen Medical Profile Solution
As a European medical device manufacturer, we faced the problem that separate pneumatic and wiring tubes were bulky, hard to bundle and time-consuming to assemble. We cooperated with OUTOU, who customized an integrated medical-grade 3-channel PU extrusion profile with precise dimensions and tight tolerance, perfectly meeting our compressed air, vacuum suction and wire routing needs. This solution cut our assembly time by 65%, solved cable bundling troubles, upgraded product appearance and passed all medical regulatory tests.
Ensuring Long-Term Performance
Standard PU tubing should not be used continuously above 60°C; high-temperature customized versions can withstand 80–110°C. PU performs well against oil and regular industrial chemicals, but keep away from strong acids, strong alkalis and polar solvents like acetone, and please do compatibility testing before application. Store products in cool, dry environment at 15–25°C away from direct sunlight, use within 12 months to avoid hydrolysis. During handling, support long profiles properly, avoid over-bending beyond the minimum bend radius, and cut with sharp blades to prevent edge fraying.

FAQ:
What are PU extruded products?
PU extruded products are custom polyurethane components manufactured through extrusion processes, including profiled strips, sealing strips, and non-standard PU tubing for industrial applications.
What are polyurethane profiled strips used for?
Polyurethane profiled strips are widely used in automation equipment, conveyor systems, sealing applications, protective edges, and mechanical guide components due to their high resilience and abrasion resistance.
Can you manufacture custom non-standard PU tubes?
Yes. As a polyurethane extrusion manufacturer, we provide fully customized non-standard PU tubes based on drawings, including special diameters, wall thicknesses, irregular cross-sections, and multi-cavity structures.
What is the diameter tolerance of your custom PU tubing?
Our advanced online extrusion control system ensures dimensional tolerance within ±0.12mm, providing reliable fit and assembly precision.
