What Is Urethane Rubber?

Posted by Sioux Rubber & Urethane Team on Jul 27, 2023 10:35:20 AM

Urethane is derived from ethyl ester and is a crystalline compound that is colorless and odorless. Although urethanes are not quite rubber, they fall into a category of materials known as rubber. Urethanes fall somewhere between plastics and rubber. They are more pliable and softer than plastic, but also harder than rubber. It is these qualities that contribute to their exceptional load-bearing abilities, impact resistance, and overall toughness.

Urethane Rubber Properties and Characteristics

Inherently resistant to oil, urethane rubber materials and components perform exceptionally well in applications that expose them to oil or fuel. Their load-bearing capabilities also allow urethane products to resist cracking or becoming brittle when exposed to extreme temperatures. Urethane is a unique elastomer that has the ability to resist:

  • Abrasions
  • Bacteria
  • Chemicals
  • Fungus
  • Impacts
  • Ozone attacks
  • Oxygen attacks
  • Radiation

Urethane Rubber Markets and Applications

Urethane can be molded into a wide range of shapes and sizes in the production of plastics. In its liquid form — spar urethane — it can be used as an adhesive, coating, or sealant.

What is Spar Urethane?
Spar urethane is a type of varnish that is water-resistant and used in outdoor applications. It is beneficial for protecting wood from damage that might occur from water, sun, or wind. It creates a glossy finish that enhances the appearance of the wood and extends its lifespan, making it a popular choice for boats, decks, and outdoor furniture.

Urethane can also be used in the production of human pharmaceutical products, veterinary medicines, and insecticides. Urethane’s unique traits make it a valuable resource to many industries, including:

  • Automotive
  • Building insulation
  • Footwear
  • Furniture and bedding
  • Freezers and refrigerators
  • And others

Urethane can be offered in a variety of types, shapes, compression rates, and hardness levels. Urethane is excellent at shock absorption and sound dampening. It is also abrasion- and tear-resistant.
