Harnessing TPU hoses and tubes in a wide range of industrial applications
The mechanical properties and versatility of TPU material make it a popular choice in a vast array of industrial applications, from slurry hoses and fracking hoses to potable water hoses and medical tubing.
As well as offering excellent flexibility and durability, high mechanical strength, and good resistance to chemicals, TPU can be processed in a variety of ways, including extrusion and injection molding. In turn, it enables designers and manufacturers to create spiral hoses, textile-reinforced hoses, lay-flat hoses, standard tubes, preformed tubes, connectors, and more.
At Covestro, we’ve designed our Desmopan® TPU solutions to provide the high performance required by a range of industrial applications – helping to keep people safe and support efficient operations.
Ensuring durability and compliance in spiral hoses and potable water hoses
For spiral hoses, the processing and in-use properties of the TPU are key. These applications not only need to be abrasion-resistant, tear-resistant, hydrolysis-resistant, and microbe-resistant, but they also need to be transparent. To improve production speeds, materials with high melt stability are also needed. What’s more, many spiral and potable water hoses must comply with food and drinking water regulations set out by the EU, the US FDA, and other authorities.
The Desmopan® portfolio from Covestro offers multiple options for this segment. Suitable for extrusion and injection molding methods, our TPU grades enable the production of spiral hoses of all shapes, sizes, and functions.
Enabling performance under pressure in textile-reinforced hoses
Flexibility and resistance to kinking are key requirements of textile-reinforced hoses, whether they’re life-saving fire hoses, everyday garden hoses, or transfer hoses in heavy industry. That’s where TPU comes in: either extruded through the fabric to form a single layer or as a coating in a multi-layer product.
The Desmopan® TPU range is the ideal solution for textile-reinforced hoses. Our solutions are designed to withstand abrasion, tear, kinking, oil, microbes, hydrolysis, and UV radiation, while also offering drinking water compliance and good flexibility even at low temperatures – making Desmopan® the ideal choice for this high-pressure segment.
Delivering ultimate flexibility in tubes
Types of tubing are as varied as the applications they serve. Form factors include standard smooth tubes, spiral or coiled tubes, and preformed tubes, and they can be produced by single-, co-, or multi-layer extrusion. No surprise, then, that processability is an important consideration in choosing the right TPU for a particular tube application.
When you choose the Covestro Desmopan® range, you gain processability and much, much more – including high tensile strength, resistance, flexibility, and stability. Plus, our TPUs include food-quality grades and solutions for pneumatic tubes that can stand up to burst pressure and creep. No matter your unique needs, Covestro can help you find the right TPU resin for any tube.
