XPS Foam Core densities from 45 to 50 kg/m³ offer tailored performance across insulation, commercial, and structural applications. Increasing density enhances strength and stability while reducing insulation efficiency, enabling precise material selection based on load requirements, weight targets, processing needs, and overall project cost.
XPS Foam Core is available in a wide range of densities to meet diverse performance and cost requirements across construction, transportation, marine, and industrial composite applications. From 45 kg/m³ insulation-grade cores to 50 kg/m³ high-density structural cores, density is the primary factor influencing mechanical strength, dimensional stability, weight, and application suitability.
This comparison provides a clear, professional overview of how XPS Foam Core performance evolves across the 45–50 kg/m³ density spectrum, helping engineers, designers, and procurement teams select the most appropriate grade for their projects.
Density Range Classification
| Density Range | Typical Classification | Primary Function |
|---|---|---|
| 40 kg/m³ | Medium Density | Commercial panels, interior systems |
| 50 kg/m³ | High Density | Semi-structural sandwich panels |
Mechanical Performance Comparison
Density directly correlates with mechanical strength. Higher density XPS Foam Core provides increased resistance to compression, shear, and bending.
Weight vs. Strength Trade-Off
One of the core advantages of XPS Foam Core is its ability to deliver application-specific performance by adjusting density.
Cost and Processing Considerations
As density increases:
- Material cost per cubic meter increases
- Mechanical machining becomes easier and cleaner
- Adhesion performance with composite skins improves
- Panel thickness can often be reduced due to higher strength
Selecting the optimal density therefore requires balancing structural requirements, weight targets, processing methods, and overall project cost.
Conclusion
XPS Foam Core densities from 45 kg/m³ to 50 kg/m³ provide a comprehensive performance spectrum, enabling precise material selection for nearly any application scenario. Low-density grades excel in insulation and lightweight uses, while high- and ultra-high-density grades deliver the mechanical strength and dimensional stability required for structural sandwich panels.
