Polyurethane wheels are a popular choice for commercial, as well as consumer, casters. A type of synthetic material, polyurethane consists of organic compounds — polyols and diisocyanates — joined by carbamate or urethane links. This unique composition distinguishes it from plain rubber. Below are six noteworthy benefits of polyurethane wheels for casters.
#1) Handle Heavy Loads
You can rest assured knowing that polyurethane wheels can handle heavy loads. They have a higher load capacity than many other types of wheels, including rubber wheels. Some of them, in fact, can handle over 1,000 pounds per caster. Assuming you use four casters, that’s a combined load rating of 4,000 pounds.
#2) Strong and Durable
Polyurethane wheels are very strong and durable. They typically have a Shore Hardness Rating of 90 to 100. Considering the scale ranges from zero to 100, that makes polyurethane a very hard material. As a result, polyurethane wheels can take a beating without succumbing to dents, cracks or other forms of damage.
#3) Gentle on Floors
They may be strong and durable, but polyurethane wheels are still gentle on floors. They won’t scratch or leave marks on floors. So, if you’re looking for casters to use on hardwood, laminate or other types of indoor floors, you may want to look for polyurethane wheels.
#4) Wide Temperature Range
Another benefit of polyurethane wheels is a wide temperature range. They aren’t susceptible to heat- or cold-related damage. Polyurethane is known for being resistant to both cold and heat. Polyurethane wheels can handle temperatures as low as minus 40 degrees Fahrenheit and as high as 180 degrees Fahrenheit.
#5) Chemical Resistance
Polyurethane wheels are also resistant to many chemicals. They can withstand exposure to oils, greases, solvents and many other harsh chemicals. With their chemical-resistant properties, polyurethane wheels are commonly used in industrial settings, such as food processing plants, manufacturing facilities and even laboratories.
#6) Excellent Traction
Finally, polyurethane wheels offer excellent traction. They grip to the floors on which they are used, thereby preventing slips on smooth surfaces. You can also find polyurethane wheels in different tread styles. Some of them are flat, whereas others have crowd tread for maximum traction and load stability.
In Conclusion
Polyurethane wheels offer a powerful combination of strength, durability and versatility that make them a smart choice for a wide range of applications. Their ability to support heavy loads without damaging floors, withstand extreme temperatures and resist harsh chemicals sets them apart from traditional rubber or plastic alternatives.
