Why Polyurethane?

Polyurethane (/ˌpɒliˈjʊərəˌθeɪn, -jʊəˈrɛθeɪn/; often abbreviated PUR and PU) refers to a class of polymers composed of organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials. This chemical variety produces polyurethanes with different chemical structures leading to many different applications. These include rigid and flexible foams, varnishes and coatings, adhesives, electrical potting compounds, and fibers such as spandex and polyurethane laminate (PUL). Foams are the largest application accounting for 67% of all polyurethane produced in 2016.

A polyurethane is typically produced by reacting an isocyanate with a polyol. Since a polyurethane contains two types of monomers, which polymerize one after the other, they are classed as alternating copolymers. Both the isocyanates and polyols used to make a polyurethane contain two or more functional groups per molecule

Polyurethane is an extremely versatile elastomer used in countless applications worldwide. Polyurethane’s mechanical properties can be isolated and manipulated through creative chemistry which creates a number of unique opportunities to solve problems with performance characteristics unequaled in any other material. Our understanding of how to seize these opportunities allows Precision Urethane to provide “Flexible Solutions Through Polymeric Innovation.”

Polyurethane – versatile material with durable properties

  • Superior insulation performance
  • Of all conventional insulating materials polyurethane currently offers the highest insulation performance
  • More living space
    As an insulating material, polyurethane permits a thinner insulating layer than other materials, which results in more free space for building interiors
  • High aging durability
    Polyurethane is mechanically durable, moisture-resistant, temperature-resistant, and chemically stable
  • Great versatility
  • Rigid polyurethane panels can be cut to any size using simple tools
  • Outstanding energy balance
  • Viewed over its entire life cycle, polyurethane displays an excellent energy balance
  • Good fire protection performance
  • Polyurethane is thermally stable, does not melt, drip or smoulder, and polyurethane foams fulfil the majority of fire safety norms within the construction industry.
  • Renovation and new buildings
  • Broad range of applications in these key areas
