Is Polyurethane Really Better than Plastic or Rubber?

At Urethane Systems Plus Inc, we devote our working lives to the manufacture of quality polyurethane products.  So you may wonder: what’s so great about polyurethane? The answer is in the versatility and many advantages over competing materials. If you’re curious as to why design engineers and production managers ought to make a point of considering polyurethane as the base for their parts and products, read on to learn more.

What is Polyurethane? Polyurethanes (also called “urethanes”) are any of a family of elastomers, an artificial rubber. They are unique in combining the strength of rigid plastics with the flexibility and elasticity of rubber. Hoses, automotive bushings, seat foam, skateboard wheels, and Spandex are all common polyurethane applications.

Advantages of Polyurethane: Substituting polyurethane components for rubber or plastic may offer the following advantages, just to name a few.

  • Durability.  Polyurethane has exceptional abrasion and tear-resistance, typically better than rubber. It also has increasing load-bearing capacity, impact-resistance, and excellent wear properties.
  • Density Range.  Polyurethane can be fabricated to be as soft as seat foam or hard as a table top!
  • Flexibility.  Polyurethane’s outstanding elastic memory makes it a popular choice for furniture components.
  • Pliability.  The combination of durability and pliability makes polyurethane the material of choice for medical supplies like feeding tubes or anatomical models.

In our next blog, we’ll discuss how the manufacture of polyurethane is an advantage in and of itself.
