What Is TPU Extruded Tube?

TPU Extruded Tube is a hollow cylindrical profile manufactured from thermoplastic polyurethane via the extrusion process. TPU is a versatile thermoplastic elastomer that combines the elasticity of rubber with the processability of plastic, making it ideal for extruded tube production.

Core Properties of Quality TPU Extruded Tube

Actual testing from our in-house lab shows that high-quality TPU extruded tubes have a unique balance of properties that outperform many other thermoplastic alternatives. In practice, we find that TPU tubes offer:

• Excellent abrasion and tear resistance (2-10 times better than rubber tubes)
• Good resistance to oils, greases, and many common chemicals
• Wide operating temperature range from -40°C to 120°C
• High flexibility even at low temperatures

Step-by-Step Manufacturing Process

From our 15+ years of manufacturing experience, the production of precision TPU extruded tube follows these core steps:

1. Raw material preparation: TPU pellets are dried to remove moisture, then blended with required additives (colorants, stabilizers, plasticizers) based on end use requirements.
2. Extrusion: The blended compound is fed into a temperature-controlled extruder, melted, and forced through a custom-shaped die to form a continuous hollow tube profile.
3. Cooling and sizing: The warm extruded tube is pulled through a calibrated water cooling tank to set its exact inner and outer diameter.
4. Quality inspection and finishing: The tube is cut to custom length, tested for dimensional accuracy and defects, then packaged for shipping.

TPU Extruded Tube vs Other Common Thermoplastic Tubes

When selecting a tube material for your project, it is important to compare performance across key metrics. Below is a performance comparison based on 2026 industry testing data:

Industry consensus from the 2026 International Elastomer Manufacturers Association report states that TPU extruded tubes are the most versatile all-around option for most industrial and consumer applications where durability and flexibility are required.

Common Applications of TPU Extruded Tube

Due to its versatile properties, TPU extruded tube is used across a wide range of industries. Below we answer the most common questions people ask about applications:

Q: What industries use TPU extruded tubes most frequently?

A: 2026 industry shipment data shows the top industries using TPU extruded tubes are medical devices (catheters, drug delivery tubes), automotive (fuel lines, cable insulation), industrial automation (pneumatic hoses), consumer goods (drinking water hoses, sports equipment), and telecommunications (cable protection sheaths). From our own order data, over 60% of our custom TPU tube orders come from medical and industrial clients.

Q: Can TPU extruded tubes be used for food or medical contact?

A: Yes, reputable manufacturers produce food-grade and medical-grade TPU extruded tubes that meet FDA 21 CFR and ISO 10993 biocompatibility standards. In practice, we test every batch of medical-grade TPU tubes for leachables and biocompatibility to ensure compliance with global regulations. It is always important to confirm material grade with your supplier for sensitive applications.

How to Select the Right TPU Extruded Tube for Your Project

Choosing the correct TPU extruded tube requires considering several key factors. From our experience working with hundreds of product design teams, we recommend following this selection framework:

Confirm Dimensional and Tolerance Requirements

First, define your required inner diameter, outer diameter, and wall thickness. For precision applications like medical catheters, tolerances as tight as ±0.02mm can be achieved, while general industrial applications often accept wider tolerances of ±0.1mm to ±0.5mm.

Match Material Grade to Working Environment

Next, consider the working conditions: if the tube will be exposed to repeated bending, select a lower shore hardness (70A-85A) for more flexibility. For high pressure applications, choose a higher shore hardness (85A-98A) for greater strength. If the tube will be used outdoors, select a UV-stabilized TPU grade to prevent degradation.
