There’s a number of things that can go wrong when we’re trying to move a heavy load across a floor on caster wheels no matter what their made of; dirt and debris can get caught in the bearings, threads and wires can get bound in the wheels, and when objects are stuck between the caster wheels and the floor and the load is dragged, the floors can be damaged as well.
Neoprene rubber casters can mark floors in a way that’s difficult to remove particularly if they aRe black. However, some rubber casters are produced in a grey color; these variations typically will not leave marks on the floor. Still, polyurethane is preferred in applications where protecting the floor is a concern; they do allow the transference of color commonly seen with rubber caster wheels.
If caster selection is not negotiable due to weight restrictions, CoolYeah also has flooring options that can help make the space more workable. We offer Diamond Nitro Garage Tiles that are manufactured out of impact resistant plastic. Plastic flooring is durable and easy to clean, and resistant to marking and marring.
Yet another fantastic option from CoolYeah Garage Organization, a garage door flood barrier threshold kit can be easily installed beneath your garage door to keep dirt and debris from blowing in under the garage door. These are both options that make the decision between polyurethane caster wheels and neoprene rubber caster wheels far easier to make than it might have been.
Neoprene Rubber Caster Pros and Cons
Disadvantages of Neoprene Rubber Casters
Neoprene rubber casters are not suitable for all applications. They have several intrinsic disadvantages that you must consider before choosing them for your application.
Disadvantage 1: Initial Cost. Neoprene rubber casters were tremendously popular 20 years ago. But the price of neoprene has risen quite a bit in recent years, resulting in only a few manufacturers still producing neoprene wheels. If initial cost is an important criterion for you, there are less-expensive options on the market to choose from than neoprene.
Disadvantage 2: Load Rating. Neoprene rubber casters are ideal for light-duty applications. Neoprene does not have the load rating you require for heavy-duty applications. When used in heavy-duty settings, the wheels tend to break down. For heavy-duty applications, your better option is a caster made from polyurethane.
Disadvantage 3: Chunking. Neoprene rubber casters deliver a softer and quieter ride than wheels made from harder materials, but they don’t wear as well. Unlike casters made from polyurethane, for example, neoprene wheels tend to lose pieces of tread over time. They are not as resistant to wear and abrasion.
Conclusion – When are neoprene rubber casters appropriate for you
Neoprene rubber casters are an ideal choice if you require a light-duty caster that is quiet, resists chemicals and won’t mark your floors. If you need replacement casters for carts and mobile equipment in your hospital or office setting, caster wheels made from neoprene are a great choice.
Caster Connection carries a range of neoprene casters that are idea for a wide range of indoor applications.

Polyurethane vs Neoprene Rubber Casters: Which is the Perfect Fit for You?
Back in the early days of the development and use of casters – 100 years ago or more – there were few choices for wheel materials. If you wanted hard wheels, you used metal. If you needed soft wheels, natural rubber was the main option. And if you wanted something in between, wood was a popular choice.
That all began to change in the 1930s, when there were new technical developments in synthetic materials like plastics, resulting in an explosion of choices for caster wheel materials. In particular, two rubber-like synthetic materials began to replace natural rubber.
– This is a synthetic rubber made by the polymerization of certain chemicals such as chloroprene. It is an elastomer, meaning that when stretched it has a memory, and will return to its un-stretched position, much like rubber does. Unlike rubber, however, neoprene is highly resistant to grease, oils, harsh chemicals and high temperatures. This makes it an ideal material to use for caster wheels.
– is also a synthetic rubber. It is most often made by combining solutions of two or more chemicals, pouring the mix into a mold, and casting the desired product. Producers can control the properties of the final product by varying the ingredients of the starting compounds, and through different manufacturing processes. Caster wheels made from polyurethane can be fabricated with a range of hardness, from soft to extremely hard. Depending upon the formulation, polyurethane casters can resist oil, grease and chemicals quite well.
Both materials have come a long way since the 1930s, and are now widely available in many different styles for caster wheels. In fact, because of their superior properties, they have almost totally replaced natural rubber as a choice for caster wheels.
These days, it’s often hard to tell the difference between synthetic “rubber” materials and natural rubber itself. When many of our customers want soft casters, they’ll ask us for rubber casters. We usually ask questions about their application requirements, then recommend polyurethane or neoprene casters.
Below we’ll compare neoprene and polyurethane, with the goal of helping you decide which of the two materials is the perfect fit for your needs.
Neoprene Caster Wheels
One of the chief features of neoprene wheels is their smooth, quiet operation. Though they may seem soft, solid neoprene wheels are actually very durable. They are excellent for floor protection, and are frequently chosen as casters for office seating. They work well on many different floor surfaces, but will not mark or mar the floor. They are very quiet as they roll across office flooring, especially when compared to hard plastic casters used on some office chairs.
Another desirable feature of neoprene is its chemical resistance. This makes neoprene casters ideal for use in situations where oil or grease is present. Neoprene is not affected by water, steam or harsh chemicals.
For added strength, neoprene is often bonded to a harder core material. The outer layer of neoprene forms the wheel’s tread, while the core provides the structure.
Neoprene’s properties make it a popular choice in applications like these:
- Medical and laboratory equipment, such as medical carts and IV stands
- Carts for mobile computers
- Office furniture and seating, especially ergonomic chairs
- Harsh chemical wash-down areas, in hospitals or food processing facilities
Note that most of the uses mentioned above are for office, medical or light industrial settings. For heavy-duty industrial applications, polyurethane casters are popular. We’ll discuss those next.
Polyurethane Caster Wheels
It’s important to know that not all polyurethanes are equal – the material is available with a tremendous range of characteristics. During fabrication, manufacturers have many different chemical compounds to choose from, and various manufacturing processes which determine characteristics of the resulting products. They choose different polyurethane compounds, based upon the intended application situation. Is it important that the caster be non-marking, or make no audible noise? Will it be operated at low speeds or high speeds? Will it be used continuously, or only occasionally? Each of these situations may require a different polyurethane formulation.
– while often considered to be non-marking and floor protective, polyurethane casters function better in this regard on some floors than on other floors. They work well on hard surfaces such as ceramic tile, concrete, or hardwood – but usually are not suggested for use on linoleum, vinyl or soft wood floors. Neoprene may be a better choice for softer flooring materials.
Low-speed versus high speed
– as polyurethane casters roll, they flex as they load and unload while the caster is in motion. This constant loading and unloading causes internal heating in the polyurethane – and as speeds increase, so does the heating. If too much heat builds up internally, it can actually melt the polyurethane, leading to a failure called a “blowout”. To avoid this problem, the manufacturer will formulate a polyurethane able to withstand the heat generated by higher speeds. This means that if you are looking for casters to be used in a towline operation, make sure you choose models rated for the speeds at which your equipment will operate.
Occasional versus continuous duty
– some polyurethane caster wheels, when under load and stationary (not moving) for long periods of time, may be prone to developing flat spots. To avoid this, manufacturers modify their compounds, and create polyurethane wheels that maintain their shape when loaded but not moving. If you need polyurethane casters for a heavy equipment cart that rarely moves, for example, be sure you choose casters that keep their shape.
