Durability and Flexibility

Urethane is a more durable and flexible product than any plastic. While plastics do last a long

time, products made of plastic will wear out before a urethane product does. They are also

more likely to break, abrade, or deteriorate before urethanes will.

One of the most unique aspects of urethane is the material’s elastomeric ability. This means

that urethanes can be stretched or extended significantly. And when released, they will return

to their present size. Plastics cannot do this. In fact, if you attempt to stretch or extend a plastic

piece, it will remain stretched, or it will break.

Abrasion Resistance

Another impressive quality of urethane is the material’s resistance to abrasion. Urethane wheels

and rollers will last significantly longer than the same parts made of plastic. Manufacturers

who use urethane parts in their machines are satisfied with the lifespan of the urethane parts

because they do not break down when friction breaks down other materials.

Cost Similarities

Making parts from plastic or urethane have relatively similar costs. But, what cost less is making

the casts for urethane products. Most of the casts are made out of silicon, which is inexpensive.

However, plastic injection molding is not expensive, but the parts made this way do not last as

long as urethane ones do. So, in the long run, urethane parts are more cost-effective simply

because they have a longer lifespan than their plastic counterparts.

Load Bearing

Urethanes have incredible load-bearing performances. Plastics tend to break when they are

pushed to their limits, but urethanes often surprise engineers with home much they can tolerate.

Their elastomer quality gives them better shock absorption when impacts reach higher levels.

Temperature and Friction

When urethane is put under the stress of heat and friction, it continues to perform. Of course,

like all products, there are temperature limits. One of those is the low-temperature threshold,

and urethanes will continue to respond in temperatures that reach -60°F and more.

Sound and Noise

Urethanes are frequently used to dampen noise. For example, polyurethane foam is often

injected into car doors to reduce road noise. While plastic isn’t necessarily a noisy material,

urethanes are generally quiet because they absorb noise. Plastic can be noisy, especially

crinkly bags and rigid toys made from the material.
