PVC Tubing vs. Polyurethane Tubing

In industrial fluid transfer, pneumatic systems, or automation equipment, the choice of hose directly impacts the system's efficiency, safety, and lifespan. Whether it's for conveying compressed air, liquid media, or protecting delicate cables, a well-matched hose can significantly reduce maintenance costs and minimize downtime risks. However, with the myriad of material options available in the market—especially the commonly used PU (Polyurethane) hose and PVC (Polyvinyl Chloride) hose—many engineers or procurement staff, especially those with limited experience, often face a dilemma:

• PVC hoses are cost-effective, but can they withstand frequent bending?

• PU hoses offer excellent abrasion resistance but are more expensive; is the investment worthwhile?

• What are the differences between the two materials in terms of chemical resistance, temperature adaptability, and lifespan?

  
  

In fact, there is no "absolute better" option, only the "better fit" for a particular application. Both PVC and PU hoses have their unique advantages, but choosing the wrong material can lead to frequent replacements or, in the worst case, system failures and safety risks.

In this article, we will provide a comprehensive comparison through performance parameters, real-world application analysis, and cost-benefit assessments to help you clearly understand:

• When to choose PU hoses

• When PVC hoses are the better choice

• Key factors often overlooked (such as UV resistance, food-grade certification, etc.)

  
  

Whether you're designing an automation production line, upgrading a pneumatic system, or simply replacing aging hoses, this comparison guide will help you make precise and cost-effective decisions.

PVC Tubing vs Polyurethane Tubing

Polyurethane and PVC are both thermoplastic materials. Both PVC and PU can be molded at higher temperatures. After cooling, they will solidify again. Manufacturers can shape them into any shape, including hoses. Based on their physical and material properties, they are suitable for various applications. However, in many cases, one material may have advantages over another in certain applications.

What is PVC Tubing?

PVC pipe (polyvinyl chloride pipe) is a plastic pipe manufactured by extrusion molding process using polyvinyl chloride resin as the main raw material. Its name comes from the abbreviation of "Polyvinyl Chloride" in English, and it is currently the third most widely used synthetic plastic material in the world (after PE and PP)

Application

Construction field: drainage pipes, wire conduit

Low pressure irrigation: drip irrigation system, horticultural water pipe

Laboratory: Chemical waste discharge pipe

Temporary pneumatic connection: Compressed air pipeline for low-frequency use

Limitations Over PVC Tubing

Poor Flexibility & Fatigue Resistance

Stiffness: Rigid PVC tubes cannot withstand repeated bending, making them prone to cracking in dynamic applications (e.g., robotics, moving machinery).

Work Hrdening: Repeated flexing causes PVC to become brittle over time, leading to catastrophic failure.

Comparison: PU tubing retains flexibility even after millions of bending cycles.

Limited Temperature Range

Low-Temperature Brittleness: PVC becomes brittle below -5°C (23°F), risking fractures in cold environments.

High-Temperature Softening: Deforms at temperatures above 60°C (140°F), limiting use in steam or hot fluid systems.

Comparison: PU tubing typically handles -40°C to 90°C (-40°F to 194°F).

Low Abrasion Resistance

Wears Quickly: PVC surfaces degrade rapidly when rubbed against machinery or dragged across rough surfaces.

Not for Drag Chains: Unsuitable for cable carriers or high-motion applications.

Comparison: PU tubing offers 10x longer lifespan in abrasive environments.

What is Polyurethane Tubing?

Polyurethane Tubing is known for its flexibility, toughness, and resilience.

Manufactured via extrusion process, available in multiple diameters & wall thicknesses.

Performance Benefits

✅ Extreme Flexibility – Bends/stretches easily without kinking (superior to PVC in dynamic applications).
✅ Exceptional Abrasion Resistance – Withstands wear, friction, and impact better than most plastics.
✅ High Tear Strength – Resists damage during installation and heavy use.
✅ Wide Temperature Range – Performs from -80°F to 200°F (-62°C to 93°C).
✅ Chemical & Moisture Resistance – Handles oils, solvents, and water (but not strong acids/alkalis).
✅ Lightweight – Easier to handle than metal/rubber hoses.

Application

Pneumatic systems 

Hydraulic lines

Robotics & automation

Medical & food-grade uses 

Limitations

Not for aggressive chemicals – May degrade with prolonged exposure to certain solvents.
Higher cost than PVC – Justified by longer lifespan in demanding conditions.

PVC vs. Polyurethane: Similarities and Differences

Similarities:

Both are versatile and widely used in various industries.

Both can be molded into different shapes for specific applications.

Both offer resistance to a variety of environmental factors.

Differences:

PVC is more rigid, with less durability and impact resistance compared to PU, which is more flexible and durable.

PU is generally better at resisting chemicals, oils, and abrasion, making it more suited for industrial applications with tough environments.

PVC is cheaper and is typically used for construction and plumbing, while PU is used for more demanding applications like automotive, industrial hoses, and medical equipment.

Conclusion

This article examined the characteristics and uses of PVC and polyurethane tubing. PVC is known for its excellent chemical resistance and cost-effectiveness, making it a popular choice for plumbing, irrigation, and medical applications. In contrast, PU tubing stands out for its superior flexibility, high abrasion resistance, and durability, making it suitable for use in pneumatic systems, robotics, and fluid transport. Both materials are widely used across a range of industries, providing reliable solutions for diverse fluid handling needs.

The decision between PVC and polyurethane tubing depends on the specific needs of each application. PVC is best suited for environments where chemical resistance, cost-efficiency, and electrical insulation are key priorities. Meanwhile, PU is the ideal choice for applications requiring high flexibility, resistance to wear and tear, and a wider temperature range.
