What Is TPU Extruded Tube?

TPU Extruded Tube is a hollow thermoplastic polyurethane profile made via continuous extrusion molding. It combines the elasticity of rubber and the processability of thermoplastic, making it a versatile solution for multiple industrial and commercial use cases. As a raw material manufacturer, we control TPU formulation from the source to ensure consistent tube quality.

In practice, TPU extruded tubes outperform most alternative plastic and rubber tubes in dynamic application scenarios. 2026 industry research shows TPU extrusion technology has improved 15% in dimension accuracy over the past 5 years, expanding its use in high-precision fields.

Q: What core properties do quality TPU extruded tubes have?

A: High-quality TPU extruded tubes feature excellent abrasion resistance, high tensile strength, good flexibility at low temperatures, and strong resistance to oil, grease and many chemicals. From our test data, TPU tubes can withstand over 100,000 bending cycles without cracking, which is 3 times higher than standard PVC tubes.

How Are TPU Extruded Tubes Manufactured?

The manufacturing process of TPU extruded tubes requires strict control of temperature and material moisture to avoid quality defects. Below is the standard production process we use at SPP New Material:

1. Raw material preparation: Custom-formulated TPU pellets are dried at 80-90°C for 2-4 hours to remove excess moisture, which prevents bubbles and surface defects.
2. Extrusion molding: Dried pellets are melted in a temperature-controlled extruder, then forced through a precision die to form the continuous hollow tube profile.
3. Cooling and sizing: The molten tube passes through a vacuum water cooling tank to set its exact inner and outer diameter.
4. Cutting and quality inspection: The continuous tube is cut to customer-specified length, then inspected for dimension tolerance, surface quality and mechanical properties before packaging.

Q: Why does raw material quality matter for TPU extruded tubes?

A: In our experience, 70% of TPU tube quality issues come from low-quality raw TPU material. As a integrated TPU raw material and finished tube manufacturer, we produce our own TPU pellets, so we can adjust the hardness and formula to meet specific application requirements, and ensure consistent batch quality.业内共识 is that raw material control is the core of reliable TPU extruded tube supply.

TPU Extruded Tube vs Other Common Tubes: Performance Comparison

To help you compare performance, we compiled 2026 test data of TPU extruded tube against two common alternatives, PVC tube and natural rubber tube:

2026 latest industry data shows the global demand for TPU extruded tubes is growing at 5.8% annually, driven by the expansion of medical device and industrial automation sectors.

Common Applications of TPU Extruded Tubes

TPU extruded tubes are used across a wide range of industries thanks to their adjustable properties. Below are the most common use cases:

Q: Can TPU extruded tubes be used for medical applications?

A: Yes, medical-grade TPU extruded tubes meet USP Class VI and ISO 10993 biocompatibility standards. They are widely used for catheters, infusion tubing, medical device components, and drug delivery systems. Actual test data from 2026 shows medical-grade TPU has lower leaching than many alternative materials, making it ideal for single-use medical devices.

Q: What other industries use TPU extruded tubes?

A: Other major industries include: industrial automation (air hose, cable protection sleeves), consumer goods (inflatable product tubes, drinking water hoses), automotive (fuel line protection, wire harness sleeves), and sporting goods (braided hose liners, inflation valves). From our customer cases, TPU extruded tubes are ideal for any application that requires flexibility and durability.

How To Select The Right TPU Extruded Tube

When selecting a TPU extruded tube for your project, you need to confirm 4 key specifications first: dimension (inner/outer diameter), TPU hardness (usually from 70A to 98A), material grade (standard, medical, food-grade), and special requirements (flame retardant, UV resistance). Trustworthy manufacturers like SPP can help you adjust the specification to fit your budget and performance needs.

Q: What tolerance can I expect for custom TPU extruded tubes?

A: For small diameter tubes (outer diameter under 10mm), we can achieve a tolerance of ±0.05mm for high-precision applications. For larger diameter tubes, the standard tolerance is ±0.1mm, which meets most industrial requirements. Actual production experience shows that tight tolerance control is critical for assembly in automation and medical devices.
