Polyurethane Belts
A more resilient option
A more resilient option
Polyurethane (PU) is a synthetic polymer. All of the PU in our belts is thermoplastic, also called TPU, meaning that it can be melted and reshaped virtually indefinitely. PU is a resilient material, designed to last longer on belting than PVC or rubber. PU is much more resistant to abrasion and, in most cases, has a better chemical resistance. PU also has a high resistance to cutting or tearing. In many cases a damaged belt will continue to perform well. This makes PU particularly suited for applications with fats and oils, where product is cut on the belt, and transferring sharp parts.
We have several PU belt styles in blue, white, and clear for food grade applications. The color blue was chosen for food grade belts as it is not a natural food color, making pieces of conveyor belt easier to spot if it breaks off into the product. Blue belts also contribute to less eye fatigue compared to white belts. Bluegreen and black are less desirable colors for conveyor belts in food processing. These belts are often used in industrial applications for their strength and resilience.
PU has a higher durometer than plastomer PVC, which results in a harder cover surface. Think of caster wheels or the sole of a boot compared to a tire on your car. Both materials have elastomeric properties which allow them to stretch and then return to their original shape. However, PU has added benefits of strength and performance.
Mol Belting Systems stocks one of the largest selections of PU belts in the industry. We offer belts with cover on one or both sides for applications ranging from troughing to horizontal-to-incline conveyance. Mol Belting also offers many standard and unique fabrications which include:
- V-Guide
- Sidewall
- Cleats or Flights
- Edgecap
- Profile
PU belts are typically rated for lower operating temperatures than PVC and rubber belts. Many PU belts are suited for environmental temperatures less than 175°F (79°C). For low and high temp options, contact moc.gnitleblom@selas for more information.
