TPU-The Material Of PU Hose

Thermoplastic polyurethane (TPU)-The material of the PU hose.
Thermoplastic polyurethane (TPU) offers a myriad of physical property combinations and processing applications. It is highly elastic, flexible and resistant to abrasion, impact and weather. TPUs can be colored or fabricated in a wide variety of methods and their use can increase a product overall durability.

Like all thermoplastic elastomers, TPU is elastic and melt-processable. In addition, it can be processed on extrusion, injection, blow and compression molding equipment. It can be vacuum-formed or solution-coated and is well suited for a wide variety of fabrication methodologies.

Normally , there are two types TPU are used in the PU hose producing. One it the Ester based TPU, another is the Ether based TPU.

Ester based PU hose is less expensive and generally stonger with higher tensile strength.However,applications should be limited to area of consistent low temperature and where high and continued flexibility is essential.

Ether based PU hose will not break down or be affected in any way of moisture,more flexible at low temperature.It has the characteristics of elastomer with good elongation and recovery along with many of the desirable properties.Very suitalbe for durable using in machines.

Regarding to the hardness of PU hose, there are 95A, 98A, 90A and 64D with good bend resistance. It has higher flexibility than nylon and higher flexibility in low temperature.

The Advantage of PU hose.

Abrasion resistance – Polyurethane hoses are less prone to abrasions, due to the molecular structure.
Pressure resistance – Hoses made from PU are able to withstand higher amounts of pressure, unlike less durable hoses that can weaken.
Temperature resistance – PU hoses are able to withstand more extreme temperatures. They are able to hold their flexibility in low temperatures and are able to withstand higher temperatures without the risk of abrasions.
Chemical resistance – PU has a high chemical resistance to many chemicals and solvents (with the exception of acidic media), making it ideal for industrial and pneumatic applications.

How many types PU hose there are ?

Hoses made from polyurethane are versatile and ideal for a wide range of applications. Our range of PU hoses each have unique properties, making them suitable for a number of uses, from fuel transfer to robotics.

Meanwhile, Sprial tubing, PU braided tubing, two layers tubing and double row tubing are all available.

Why Use Polyurethane Tubing?

Polyurethane tubing uses are numerous, as it is a versatile material that can be manufactured for a wide variety of jobs. It is primarily known for its ability to stretch. If you need flexibility, it is the product that you need to use. Polyurethane is also able to resist heat, cracking and punctures, making it a great for use in harsh conditions.

When we should use Polyurethane Tubing.

Anyone who needs to create a system of tubes to be laid outdoors should use polyurethane pipes because it won’t crack in the cold and is resistant to mold and other chemicals. Polyurethane hoses are also popular in the welding trade, as it has flame-resistant properties.
