What is Polyurethane?
Polyurethane is a very flexible elastomer – a synthetic polymer with elastic properties. The main advantage of Polyurethane is that it has:
Anti-Bacterial Properties
Polyurethane does not support mould, mildew, fungus or other similar growth.
Abrasion & Impact Resistance
This property helps prevent our tubing from being damaged and causing the inner contents to leak and flow out of the tubing due to external damage.
Electrical Properties
Polyurethane has excellent electrical insulation properties.
Flexibility
Our polyurethane air tubing performs well for flexible applications with a tight bend radius. This unique tubing feature provides maximum kink resistance and minimal kink memory, making it an excellent choice for use in confined spaces. This feature helps prevent tubing damage, enabling easy movement of the tube installation.
High Load-Bearing Capacity
Polyurethane has a high compressive load capacity. It may change shape under a heavy load, but it will return to its original form once removed.
Resistance to Gases, Fuels, Oils, and Water
Polyurethane will remain stable in or carrying: Gases, Fuels, Oils, and Water.
REACH, RoHS and ISO compliant
Our Polyurethane tubing is REACH, RoHS, and ISO compliant, addressing the production and use of chemical substances and their impacts on health and the environment.
Tear Resistance
Polyurethane offers high tear resistance and tensile strength.
What are pneumatic control systems used for?
Pneumatic systems and devices use pressurised air or gases to power equipment. Part of their makeup is the tubing, which will carry compressed air or inert gases. This feature is where our polyurethane tubing comes in.
Why are our Polyurethane Tubes suitable for Pneumatic Control Systems?
This pneumatic tube is suitable primarily due to the properties outlined above. They are tough, flexible and have a high load-bearing capacity, so they don’t damage easily. Additionally, they are flexible, making them easier to move, and they fit into tight compartments.
Working pressures
The working pressures for our polyurethane tubes are based on the short-term burst pressure at 20°C, applied with a 4:1 safety factor.
The maximum recommended continuous working temperature is 55°C with occasional short-term use at 85°C. Minimum temperature for use is -55°C.
Our standard coil length is 30 metres; however, if you require alternative lengths, we offer customised solutions, and our sales team will be happy to discuss your options.
All tube sizes are also available in various colours and tints.
What is Polyurethane?
Polyurethane is a versatile polymer composed of organic units joined by carbamate (urethane) links. It is widely used across many applications for its flexibility, durability, and resistance to abrasion and solvents.
What are the Advantages of Using Polyurethane Tubes?
Polyurethane tubes are known for their excellent flexibility, high abrasion resistance, superior tensile strength, good chemical resistance, and a wide range of hardness. They are often used in applications where rubber or plastic tubes might fail.
Are Polyurethane Tubes Resistant to Chemicals?
Yes, polyurethane tubes resist oils, solvents, fats, greases, and gasoline. However, their chemical resistance varies by polyurethane type and the specific chemicals involved.
Can Polyurethane Tubes Be Used for Food and Beverage Applications?
Specific grades of polyurethane tubes are suitable for food and beverage applications. Ensuring that the tube is certified for food-grade use and complies with relevant safety standards is essential.
What Temperatures Can Polyurethane Tubes Withstand?
Polyurethane tubes typically perform well across a range of temperatures, but their specific temperature tolerance varies. Generally, they can operate between approximately -40 °C and 80 °C, but specialised grades may extend this range.
How Do Polyurethane Tubes Compare to Rubber Tubes?
Polyurethane tubes often outperform rubber tubes in terms of abrasion resistance, flexibility, and durability. They are also more resistant to oils and solvents, but may be less flexible at lower temperatures than some rubber materials.
Can Polyurethane Tubes be Recycled?
Recycling of polyurethane materials can be challenging due to their chemical structure. However, methods such as regrinding or chemical recycling are feasible, but their feasibility depends on local recycling facilities and policies.
What Sizes and Shapes Are Available for Polyurethane Tubes?
Polyurethane tubes come in various sizes and diameters and can be custom-made to specific dimensions. They are usually round, but some manufacturers may offer other profiles depending on the application.
How to Store Polyurethane Tubes Properly?
Store them in a cool, dry place away from direct sunlight, extreme temperatures, and moisture. They should also be kept away from sharp objects and surfaces that might cause abrasion.
What Applications Are Polyurethane Tubes Commonly Used For?
They are widely used in pneumatic and hydraulic lines, fuel and oil transfer, material handling, robotics, medical devices, and in industries such as automotive, aerospace, and manufacturing.
Remember, the specific properties and suitability of polyurethane tubes can vary by manufacturer and polyurethane type. Always check with the supplier for the most relevant information for your specific application.
