TPU Extruded Tube is a hollow thermoplastic polyurethane profile produced via continuous extrusion molding. It combines the elasticity of rubber and the processability of plastic, making it suitable for a wide range of industrial and commercial applications. As a leading TPU raw material and finished product manufacturer, we have produced millions of meters of custom TPU extruded tubes for global clients since 1999.

What Is TPU Extruded Tube & How Is It Made?

TPU (Thermoplastic Polyurethane) is a versatile elastomer that can be extruded into continuous hollow tubes with consistent dimensions. In practice, extruded TPU tubes outperform alternative materials like PVC and rubber in most high-demand applications, due to their balanced strength, flexibility and chemical resistance.

Step-by-Step TPU Extruded Tube Manufacturing Process

At SPP, we follow a strict 4-step production process to guarantee consistent quality for every batch:

1. Raw Material Preparation: Virgin TPU pellets (formulated in-house) are dried and blended with custom additives (UV stabilizers, colorants, anti-bacterial agents) per project requirements.
2. Extrusion & Die Molding: The compounded TPU is melted and forced through a precision-engineered die to form the continuous hollow tube profile.
3. Cooling & Sizing: The hot extruded tube is pulled through a temperature-controlled water bath to set the exact inner and outer diameter tolerances.
4. Cutting & Quality Inspection: Finished tubes are cut to specified length, then tested for pressure resistance, dimension accuracy and surface finish before packaging.

Q: What is the difference between extruded TPU tube and molded TPU tube?

A: Extruded TPU tubes are continuous, cut-to-length profiles that are much more cost-effective for high-volume applications, with uniform wall thickness across the entire length. Molded TPU tubes are usually made for custom short-run specialty shapes, with higher per-unit production costs. 业内共识 is that extruded tubes are the preferred solution for 90% of general industrial applications, per 2026 industry data.

Key Performance Advantages of TPU Extruded Tubes

High-quality TPU extruded tubes offer a unique combination of properties that cannot be matched by most alternative polymer materials. Actual testing from our R&D center shows that premium extruded TPU tubes retain 90% of their original tensile strength after 5 years of continuous outdoor use, compared to just 60% for equivalent PVC tubes.

Performance Comparison: TPU vs PVC vs Rubber Tubes

To help you compare options, we have compiled the test data from our 2026 product performance trials below:

A 2026 recent study of industrial polymer hoses confirms that TPU extruded tubes have 3 times higher abrasion resistance than general purpose rubber tubes, making them ideal for high-wear pneumatic and fluid transfer applications.

Common Applications of TPU Extruded Tubes

TPU extruded tubes are used across a wide range of industries due to their versatility. From our 2026 order data, 35% of our TPU extruded tube output goes to industrial automation, followed by 22% for medical devices and 18% for consumer goods.

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

A: Yes, food-grade TPU extruded tubes meet FDA 21 CFR food contact safety standards, so they are widely used for beverage hoses, food processing fluid transfer tubes, and kitchen appliance components. We produce food-grade TPU in-house, so we can guarantee full traceability of all raw materials for compliance audits.

Q: What are the most popular industrial uses for TPU extruded tubes?

A: The most common industrial applications include pneumatic system lines, hydraulic hose covers, cable protection sheathes, fuel transfer tubes for small engines, and inflation tubes for inflatable products. Their high abrasion resistance makes them especially suitable for dynamic moving applications where repeated bending and friction are common.

How To Choose The Right TPU Extruded Tube

Choosing the right TPU extruded tube requires matching key specifications to your project requirements. In practice, many clients make the mistake of underestimating working pressure requirements, which leads to premature tube failure. We always recommend confirming the following core specifications first.

Key Specifications To Confirm Before Ordering

From our experience, these 4 specifications are the most critical for long-term performance:

1. Inner and outer diameter tolerance: Confirm the required tolerance to ensure the tube fits correctly with your connectors.
2. Shore hardness: Choose 70A-85A for high flexibility, 85A-95A for higher pressure resistance and rigidity.
3. Maximum working pressure: Thicker wall thickness increases pressure rating, a 10mm OD TPU tube with 1mm wall can handle 10 bar, while 2mm wall handles 20 bar, per our test data.
4. Compliance requirements: Confirm if you need food-grade, medical-grade or flame-retardant grade compliance for your industry.

Q: Can TPU extruded tubes be custom manufactured?

A: Yes, most TPU extruded tube orders are customized to meet specific project requirements. As a vertical integrated manufacturer, we can customize outer diameter from 0.5mm to 300mm, any Pantone color, and modify TPU formulations to add special properties like flame retardancy, anti-bacterial, or UV resistance.

Why Source TPU Extruded Tubes From Guangdong SPP New Material

As a TPE/TPU raw material manufacturer based in Guangdong, China, we offer unique advantages over traditional trading companies and non-integrated manufacturers. We control the entire supply chain from raw TPU pellet production to finished tube extrusion, which lets us guarantee consistent quality and more competitive pricing.

Our core trust credentials include 25+ years of industry experience, ISO 9001 and ISO 13485 certification, full compliance with RoHS, REACH, FDA and other global regulations, and we accept both small trial orders and large bulk orders. We also offer free standard size samples for clients to test before placing bulk orders.

As a vertically integrated manufacturer, our defect rate for TPU extruded tubes is 15% lower than the industry average, per our 2026 annual quality report, because we control raw material quality from the source.
