What are polyurethane straps?

If you need a solution for straps of Polyurethane , the first thing you should know about this product is all its advantages and characteristics. A polyurethane belt is a belt made of an elastic polymer material , which has many similarities to another material, rubber, and also has a number of properties. beneficial physical, chemical and mechanical properties .

The most in-demand polyurethane toothed belts are those of the Breco, Brecoflex, and Conti Synchronflex formats , which have been manufactured with polyurethane , a material that has a High abrasion resistance . In addition, it also features steel cord straps, which will provide it with even greater strength.

Another characteristic that we should highlight about the polyurethane straps Thanks to them, we will have a High load capacity , thanks precisely to the combination of its two main materials. These straps also They have high resistance to extreme temperatures , between -30ºC and 80ºC, although in some cases it may be necessary to adjust the design to suit the type of work to be carried out.

Other characteristics of the polyurethane timing belts They can be manufactured in different shapes, among which the following stand out: Round, pentagonal, and trapezoidal . Furthermore, none of them require any maintenance and they have a virtually unlimited lifespan due to their high resistance to wear and tear from any environmental element. In this sense, the polyurethane straps They are resistant to water, as well as dust, grease, abrasion, ozone and oils.

Finally, you should know that the Breco, Brecoflex and Conti Synchroflex polyurethane belts They are non-toxic, tasteless and painless, and therefore we can use them in processes where they have to be in direct contact with food.

Types of polyurethane belts

There is a wide variety of straps of Polyurethane , to cover any need you may have. We must keep in mind that the polyurethane straps They are made of a flexible material primarily used for power transmission via pulleys. Belts of this type are mainly used when high power needs to be transmitted over long distances, unlike belts made of other materials used between gears.

Once we take this aspect into account, we must know that the polyurethane straps We can classify them, based on their cross-section, into flat belts, trapezoidal section belts, hexagonal belts, poly-V belts and synchronized belts .

The Flat belts are those with a rectangular cross-section and a thickness that is smaller than their width. This type of belt is not very common nowadays, as we will see below that other types are used. straps of polyurethane , although it is true that they were widely used at the beginning of the century.

As we have mentioned, flat belts are uncommon nowadays, as they have been replaced in many cases by Polyurethane belts with a trapezoidal cross-section are those whose cross-section is a trapezoid. Thanks to this shape, the belt grips the pulley tightly, allowing it to withstand much more force than flat belts, and it does so without any slippage.

Another type of straps of polyurethane what we found are the Hexagonal belts , the cross-section of which is a hexagon. This type of belt is widely used in agricultural machinery because, due to its characteristics, it helps facilitate the driving of equipment with alternating rotating faces.

Continuing with the list of straps of polyurethane , we must mention the straps Poly-V belts have sections composed of multiple small triangles. Thanks to their trapezoidal tooth profile and reduced thickness, these belts are very flexible and ideal for applications with small diameters.

Finally, we must highlight the straps synchronized , also known as straps serrated either Regulating belts are those with teeth that mesh with the teeth of the pulleys. These types of belts are primarily used in processes requiring a constant load speed and have replaced flat belts in many applications.

Application of polyurethane belts in industry

We must take into account that the use of the straps of polyurethane In industry it is very varied, and can be found in a wide variety of sectors, although it is true that where we can find them most is in the pharmaceutical and food sectors.

When we talk about the use of a standard polyurethane strap In the food sector, we must be aware that there is a risk that, as a result of contact with food or water, the exposed part of the strap tensioner may corrode. To solve this problem, we have the BrecoProtect straps For the food sector, these are belts where the base of the tie rod is properly covered with polyurethane, thus preventing wear and tear. Furthermore, these belts also solve the problem of the tie rods at the beginning and end of the belt, which are often exposed in other applications. straps BrecoProtect For the food industry, we have polyurethane-sealed edges, so we can rest assured throughout the entire food production process.

The pharmaceutical sector also has specific requirements that polyurethane belts must meet. Similar to the food industry, belts here must be resistant to cleaning products and water, and while polyurethane is highly resistant, it may not be sufficient in the most demanding applications. Therefore, in these sectors, belts made of a more resistant type of polyurethane are used, which also comply with all the necessary regulations required by the European Commission and the FDA.

For those other sectors that require belts specially designed for high-performance processes, we have the belts Brecoflex Move and Brecomove , which have greater resistance to both tension and tearing.

Finally, we must highlight that in those industries where the ecological aspect is especially important, we find belts Brecogreen and BrecoFlex Green, which are those straps that will guarantee that the polyurethane used for their manufacture comes from 37% renewable raw materials.
