Versatile Polyurethane Stands up to Harsh Environments

The Right Degree of Durability for Your Job

Polyurethane injection molding continues to meet wide-ranging demands for strong, long-lasting goods across a spectrum of industries and applications. One of the older engineered materials and first invented during the 1940s, polyurethane has adapted to technologies over time.

When used in the polyurethane injection molding process, the material’s durability and flexibility make it a viable replacement for metal, wood or rubber. Polyurethane’s durability is demonstrated by the material’s ability to withstand harsh environments, including cold, without degradation. It is generally accepted that the material will perform well in the temperature range of -62°C to 93°C (-80°F to 200°F).

In addition, polyurethane injection molding material results in goods that can vary widely in hardness from flexible to stiff. The unusually high range of hardness relies on the engineered material’s molecular structure. The polyurethane plastic injection molding process can accommodate all levels of flexibility.

Characteristics

Polyurethane is a mid-range priced, widely available material. It meets the durability demands of the most complex applications. Polyurethane is also:

  • Water-, oil- and grease-resistant
  • Wear and tear-resistant
  • A tension and compression high load capacity material
  • Resilient
  • Lighter weight for transportation cost savings
  • Bondable to other materials
  • Available as colored or UV-shielded
While polyurethane performs within harsh environments, it can become brittle at the coldest of cold temperatures. The material may also yellow when exposed to light over time unless treated before polyurethane injection molding occurs.

Industries and Applications

With its many versatile attributes, polyurethane can be found across many industries, including automotive, medical, sporting goods and consumer goods. Within these industries, popular applications include:

  • Gaskets and seals
  • Footwear soles
  • Ski boots
  • Helmets
  • Power tool handles
  • Plugs
  • Animal tags
  • Wheels
