PORON 4790-92 polyurethane foam provides excellent protection for lower energy impacts. Softer and with a slow rebound, the material is conformable yet returns to its original shape, allowing for long-term performance.

Features

  • Thickness range of .53 to 12.7 mm (.021 to .5 in.)
  • Density range of 144 to 480 kg/m3 (9 to 30lb/ft3)
  • Conformable open cell material

Benefits

  • Long lasting and durable
  • Great for gap filling and gasketing or sealing applications
  • Distributes low energy impact
