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
Environment
- Dry or Wet Service
- Solution pH
- Slurry particle size, shape, and velocity
Operating Temperatures
Applications across a broad range of temperatures, -80F to 93F
Performance properties vary with temperature
Abrasion Mechanism
Sliding – High toughness and high tear strength best
Impact – High resiliency best
Erosion / Corrosion – elastomers protect against most ferrous corrosion mechanisms
Tooling Costs
- Open casting vs. compression vs. injection molds
