How flexible is PU polyurethane tube?

PU (Polyurethane) polyurethane tubes are known for their excellent flexibility, which is one of their key characteristics. These tubes are highly flexible and pliable, making them suitable for a wide range of applications where flexibility is essential. Here are some aspects of their flexibility:

1.Bend Radius: PU polyurethane tubes can be easily bent to accommodate tight turns and bends in pneumatic or fluid transfer systems. The bend radius of a PU tube is typically smaller than that of rigid tubing materials, allowing for efficient routing and installation in confined spaces.
2.Kink Resistance: PU tubes are designed to resist kinking, which is crucial to maintaining uninterrupted fluid or air flow. Their flexibility allows them to bend without collapsing or obstructing the passage of fluids or gases.
3.Coil Memory: Many PU tubes have a coil memory, meaning they tend to return to their original shape after being bent or stretched. This feature helps reduce tangling and makes the tubes easier to store.
4.Maneuverability: The flexibility of PU tubes makes them easy to maneuver and position in various applications. They can be routed around obstacles and machinery with relative ease.
5.Temperature Flexibility: PU tubes remain flexible across a broad temperature range, making them suitable for both hot and cold environments. They do not become stiff or brittle in low temperatures, ensuring their usability in diverse conditions.
6.Resistance to Cracking: Unlike some other materials that may become brittle and crack over time, PU tubes maintain their flexibility and durability even after prolonged use.
7.Highly Elastic: PU is an elastic material, which means it can stretch to some extent without permanent deformation. This elasticity contributes to its flexibility and ability to absorb shocks and vibrations.

The flexibility of PU polyurethane tubes is a significant advantage in applications such as pneumatic systems, robotics, fluid transfer, and many others. It allows for ease of installation, reduces the risk of kinks and blockages, and enhances the overall performance and durability of these tubes.

When selecting a PU tube for a specific application, consider factors such as the required bend radius, temperature range, chemical compatibility, and pressure rating to ensure it meets the demands of the intended use case.
