POLYURETHANE

Materials

Polyurethane

At Iracore, our polyurethane is formulated by our in-house chemists to meet the specific demand it will face in your environment.

Unlike many other urethane parts manufacturers, Iracore sources raw materials from major chemical producers to create custom polyurethanes. The polyurethane formulations have been developed through decades of field knowledge to meet rigorous operating conditions in heavy industry.

With the largest computer-controlled casting machines in North America, we can create urethane parts ranging from simple small pours (a few lbs) to the large volumes (3500lbs) required to line pipe up to 60’ in length.

Key Factors

Selecting the Proper Urethane Elastomer

Hardness
  • Important factor for load bearing / compression requirements
  • 65-95 Shore A available
  • Not a great indicator of overall elastomer performance
  • Dry or Wet Service
  • Solution pH
  • Slurry particle size, shape, and velocity
  • Applications across a broad range of temperatures, -80F to 93F

  • Performance properties vary with temperature

  • Sliding – High toughness and high tear strength best

  • Impact – High resiliency best

  • Erosion / Corrosion – elastomers protect against most ferrous corrosion mechanisms

  • Open casting vs. compression vs. injection molds
