About Polyurethanes

Polyurethanes are polymeric materials formed by the reaction of liquid isocyanates with liquid polyol components. If the reaction is not designed to create gas bubbles during the reaction process, then what results is a solid cast elastomer. This for example is what skateboard wheels are made from. If though the formula is designed to create gas bubbles that expand during the reaction, then what results is a foam product.

Polyurethanes are perhaps the most versatile of polymers, since varied selection of polyol and isocyanate components can result in an enormous difference in properties achieved, such as:

  • Flexible foams for comfort, such as seating
  • Flexible foams for sound insulation
  • Rigid foams for insulation
  • Rigid foams for void fill
  • Cast elastomers for abrasion resistance
  • Each of the above applications has an almost infinite amount of formula combinations in between

Polyurethanes contribute greatly to the quality of our lives from the comfort of mattresses and lounge suite cushions, to saving valuable energy in building insulation, to protecting steel for premature wearing in the mining industry.
