How to Know When to Use Urethane

A common misconception in the oil and gas industry is that rubber parts are cheaper than polyurethane parts. Urethane can actually be cheaper, particularly in situations where you need larger parts/quantities or several identical parts. The expensive part of casting urethane parts is typically creating the mold. However, once the parts have been molded, there is no machining necessary. If you need a smaller production run, or parts that need grinding and machining, rubber may be the better choice. What else makes urethane different?

Cast Urethane Benefits

  • Its strength makes it more suitable for certain applications than rubber
  • It’s tougher, stronger, more durable, and more versatile than rubber
  • It has customizable and adjustable chemical properties for various applications


The main difference between rubber and urethane is the cost. For a customizable solution, it’s better to go with polyurethane. For a more wallet-friendly option, it’s better to go with rubber.
