How to Manufacture Abrasion Resistant Custom Urethane Parts

When it comes to creating custom polyurethane parts, there’s no material – be it an elastomer, plastic or metal – that stands up to abrasion like urethane does. In fact, in some reports, urethane is shown to be ten times more resistant than these materials. If you’re looking for custom urethane parts, there is no better option than using polyurethane.

What Types of Abrasion Does Urethane Prevent?

While abrasion is often just seen as abrasion, there are specific movements that cause those fractures, nicks and bumps. Was it due to a fluke bump in the process? Something sliding on the custom part? Or something of high velocity that hit the part’s surface? While urethane is well suited to prevent against nearly all types of abrasion, it is best suited for the following:

  •        Sliding Abrasion
  •        Impingement Abrasion

These specific types of abrasions can really diminish the effects of your custom parts. Fortunately going with custom urethane parts is a viable, cost effective option that is incredibly resistant to abrasion.


What is Sliding Abrasion and How Do Custom Urethane Parts Prevent Abrasion?

Sliding abrasion is when tiny tears occur due to a localized area of high strain when one item slides on top of or alongside another item. These little tears leave parts liable to break down over time and can accumulate to the point of breakage. Fortunately, custom urethane parts are able to withstand such tears due to their anti-abrasion qualities. Now, when items slide against each other (intentionally or by accident) you have an extra layer of security by using urethane.

Using custom urethane parts prevents minor damages from becoming long term, critical damages that completely break the part down. With impingement abrasion, it’s a bit different from sliding abrasion. You can think of impingement abrasion as a rock being thrown at a surface. What is going to prevent the most damage: a surface that is hard and not flexible, or a surface that can absorb the energy of the impact from the rock due to its softer, more resilient material?


Custom urethane parts have already been used for decades due to the sole fact that they are so resistant to abrasion. If you are using a project that tends to wear and tear materials, consider using custom urethane parts as that is the most abrasion resistant material available for commercial use.
