Hot Cast Prepolymers

Hot Cast Prepolymers

Typical Applications Include:

  • Oil & Gas
  • Mining
  • Industrial Tires & Wheels
  • Recreational & Amusement Wheels
  • Belting
  • Timber & Forestry
  • Pulp & Paper
  • Printing & Coating
  • Marine
  • Steel & Metal Manufacturing

Hot cast urethane prepolymers are used in the most rigorous applications where the highest performance is required. Processing of these materials generally involves heated components and tooling along with a hot post-cure to optimize properties. In most cases, low to medium cost mixing equipment and tooling are adequate.
