In industrial materials sourcing, “high-density polyurethane foam” is a widely used term referring to foam materials with excellent compression resistance, thermal insulation, or structural support performance.
At XYFoams, we specialize in microcellular polyurethane foam solutions with densities ranging from 60 kg/m³ to 600 kg/m³, precisely engineered for use in new energy vehicle battery systems, 3C electronics, railway infrastructure, and industrial equipment.
Whether you require ultra-thin, soft, adhesive-backed foam for sensor sealing, or rigid, high-density foam for battery pack structural support, we can tailor the formulation, density, and performance level to your exact application scenario.
Foam performance must be matched to the functional environment—not judged by density alone.
| Density Range (kg/m³) | Recommended Series | Typical Applications |
|---|---|---|
| 200–320 | USF-PSD, PSS BTP | Camera trim rings, dust-proof gaskets, ultra-light cushioning |
| 250–320 | USF-PMD, PSS BT1/2 | Display cushioning, ultra-thin sealing, PCB protection pads |
| 200–600 | USF-PFT, USF-PST | Wearables, slow/fast rebound keypads, structural gaskets |
| 320 | INF-MH32 | Battery module sidewall buffers, cold plate support |
| 320–400 | INF-HH32, INF-HH40 | Structural support, prismatic cell insulation & buffering |
| 320–480 | USF-PHD | Load-bearing pads, railway equipment vibration damping |
