What are polyurethane belts?

If you need a solution forpolyurethanebelts, 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 with another material, rubber, and also has a number ofbeneficial physical, chemical, and mechanical properties.

The most popular polyurethane timing belts are the Breco, Brecoflex, and Conti Synchronflex models, which are made frompolyurethane, a material withhigh abrasion resistance. In addition, they also feature steel cord reinforcement, which provides them with very high strength.

Another feature ofpolyurethane belts that we should highlightisthat they offerhigh load capacity, thanks precisely to the combination of their two main materials. These beltsare alsohighly resistant 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.

Another feature ofpolyurethane timingbeltsisthat they can be manufactured in different shapes, includinground, pentagonal, and trapezoidal. Furthermore, none of them require any maintenance whatsoever, and they have a virtually unlimited service life due to their high resistance to wear and tear and to any environmental factors. In this regard,polyurethane beltsareresistant to water, dust, grease, abrasion, ozone, and oils.

Finally, you should know thatBreco, Brecoflex, and Conti Synchroflex polyurethane beltsarenon-toxic, tasteless, and painless, and can therefore be used in processes where they come into direct contact with food.

Types of polyurethane belts

There is a wide variety ofpolyurethanebelts available to meet any need you may have. It should be noted thatpolyurethane beltsare madeof a flexible material used mainly for power transmission via pulleys. Belts made from this type of material are mainly used in cases where high power needs to be transmitted over long distances, unlike belts made from other materials used between gears.

Once we have taken this aspect into account, we should note thatpolyurethane belts canbeclassified, based on their cross-section, intoflat belts, trapezoidal belts, hexagonal belts, poly-V belts, and synchronized belts.

Flat belts are those that have a rectangular cross-section and are thinner than they are wide. This type of belt is not very common today, as we will see below, other types ofpolyurethanebelts are used, 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 bytrapezoidal polyurethane belts, which are those with a trapezoidalcross-section. Thanks to this shape, the belt grips the pulley, enabling it to transmit much more force than flat belts, and what's more, it does so without any slippage.

Another type ofpolyurethanebeltwe findis thehexagonal belt, which has a hexagonal cross-section. These types of belts are widely used in agricultural machinery because their characteristics help facilitate dragging with alternating rotation faces.

Continuing with the list ofpolyurethanebelts, we must mentionPoly-Vbelts, which have sections composed of multiple small triangles. Thanks to their trapezoidal teeth and reduced thickness, these belts are very flexible and ideal for work with small diameters.

Finally, we must highlightsynchronizedbelts, also known astoothedortimingbelts, which have teeth that mesh with those of the pulleys. These types of belts are mainly used in processes that require a constant load speed, and have replaced flat belts in many cases.

Application of polyurethane belts in industry

We must bear in mind thatpolyurethanebelts are usedina wide varietyofindustries and can be found in a wide range of sectors, although it is true that they are most commonly found in the pharmaceutical and food industries.

When discussing the use ofstandard polyurethane beltsinthe food industry, it is important to note that there is a risk of corrosion on the exposed part of the belt's tensioner as a result of contact with food or water. To solve this problem, we offerBrecoProtect beltsforthe food industry, which have a polyurethane coating on the base of the tensioner, preventing wear and damage. These belts also solve the problem of tensioners at the beginning and end of the belt, which in other cases are also often exposed. WithBrecoProtectbeltsforthe food industry, the edges are sealed with polyurethane, giving us peace of mind throughout the food production process.

The pharmaceutical sector also has special characteristics that polyurethane belts must meet. As in the food sector, belts must be resistant to cleaning products and water, and although polyurethane is highly resistant, it may not be sufficient in more demanding cases. For this reason, in these types of sectors, we find belts made of a more resistant type of polyurethane, which also complies with all the necessary regulations required by the European Commission and the FDA.

For other sectors that require belts specially designed for high-performance processes, we offerBrecoflexMoveandBrecomove belts, which offer greater resistance to both traction and tearing.

Finally, we should highlight that in industries where environmental considerations are particularly important, we offerBrecogreenandBrecoFlexGreenbelts, which guarantee that 37% of the polyurethane used in their manufacture comes from renewable raw materials.
