PUre diversity

Flexible Foam - puroflex®

Flexible foams are elastic PU foams that are used in many different applications thanks to their usually excellent padding properties. In addition to the seating furniture industry, applications include motor vehicle and rail vehicle seats. However, they can also be used in seals and loaded damping components.

Typical properties

  • Moulded part density of 40–250 kg/m³
  • Adjustable compression load deflection
  • Dimensional stability under heat up to 100°C
  • Water is usually used as the foaming agent, but liquid CO2 is also possible

Special formulations and versions

  • Viscoelastic
  • Barium sulphate loaded for acoustic applications, e.g. in aviation
  • FIPFG seals for PU high-pressure processing
  • Dimensional stability under heat up to 150°C in special applications
  • Emission-free pursuant to RAL-ZU 38
