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
