| Elongation at Break | 150 – 200% | % |
| Shore A Hardness | 20 – 30 | – |
ZF-22’s low density makes it exceptionally lightweight, a critical factor in aerospace design where every gram counts. Its tensile strength ensures durability under stress, while the elongation at break demonstrates impressive flexibility—essential for absorbing impacts and vibrations.
Thermal Performance
| Parameter | Value Range | Units |
|---|---|---|
| Thermal Conductivity | 0.025 – 0.035 | W/(m·K) |
| Operating Temperature | -60°C to +90°C | °C |
With excellent thermal insulation properties, ZF-22 can maintain stable temperatures within spacecraft, protecting sensitive equipment from extreme external conditions. Its wide operating temperature range means it performs reliably in both freezing orbital environments and scorching re-entry scenarios.
Acoustic Characteristics
| Parameter | Value Range | Units |
|---|---|---|
| Sound Absorption Coefficient | 0.7 – 0.9 | – |
| Noise Reduction Coefficient | 0.85 | – |
The foam excels at reducing noise levels, thanks to its high sound absorption coefficient. This makes it invaluable for creating quieter cabin environments in commercial aircraft and minimizing interference in communication systems aboard spacecraft.
Chemical Resistance
| Substance | Resistance Level | Notes |
|---|---|---|
| Water | Excellent | Hydrophobic |
| Fuels/Oils | Moderate | Short-term exposure recommended |
| Cleaning Agents | Good | Avoid harsh solvents |
ZF-22’s hydrophobic nature helps prevent moisture buildup, crucial for maintaining structural integrity in humid environments. While it shows moderate resistance to fuels and oils, proper handling protocols ensure long-term performance.
Electrical Properties
| Parameter | Value Range | Units |
|---|---|---|
| Dielectric Constant | 1.5 – 2.0 | @ 1kHz |
| Volume Resistivity | 10^12 – 10^14 | ?·cm |
These electrical properties make ZF-22 suitable for applications involving electronic components, providing reliable insulation without interfering with electromagnetic signals.
To put these numbers into perspective, consider this: ZF-22’s thermal conductivity is roughly half that of traditional fiberglass insulation, meaning it offers superior protection against temperature extremes. Its sound absorption coefficient surpasses many competing materials, reducing unwanted noise by up to 90%. And with a density lower than water (1000 kg/m³), it contributes minimally to overall vehicle weight—a significant advantage in aerospace design.
By balancing these parameters, polyurethane soft foam ZF-22 achieves the rare combination of being strong yet lightweight, flexible yet durable, and capable of performing across a wide range of environmental conditions. These qualities set it apart from other materials and make it indispensable in modern aerospace engineering.
Comparative Analysis with Other Materials
When it comes to selecting materials for aerospace components, engineers have a variety of options at their disposal. However, polyurethane soft foam ZF-22 stands out due to its unique blend of properties that cater specifically to the rigorous demands of space travel. To fully appreciate its advantages, let’s compare ZF-22 with three commonly used alternatives: silicone foam, neoprene rubber, and expanded polystyrene (EPS).
Weight Comparison
| Material | Density Range (kg/m³) | Weight Advantage (%) vs ZF-22 |
|---|---|---|
| Silicone Foam | 50 – 80 | +25% to +100% heavier |
| Neoprene Rubber | 70 – 120 | +75% to +200% heavier |
| Expanded Polystyrene | 10 – 30 | -12% to -75% lighter |
While EPS is lighter than ZF-22, it lacks the necessary mechanical strength and thermal stability required for aerospace applications. On the other hand, silicone foam and neoprene rubber are significantly heavier, which can become a major drawback in weight-sensitive designs.
Thermal Performance
| Material | Thermal Conductivity (W/m·K) | Operating Temp Range (°C) |
|---|---|---|
| Silicone Foam | 0.04 – 0.06 | -50°C to +200°C |
| Neoprene Rubber | 0.15 – 0.30 | -20°C to +80°C |
| Expanded Polystyrene | 0.03 – 0.045 | -20°C to +70°C |
Silicone foam offers comparable thermal conductivity but struggles with flexibility at low temperatures. Neoprene rubber has poor thermal insulation properties, limiting its use in extreme environments. EPS matches ZF-22 in thermal conductivity but fails under prolonged exposure to elevated temperatures.
Mechanical Strength
| Material | Tensile Strength (kPa) | Elongation at Break (%) |
|---|---|---|
| Silicone Foam | 80 – 120 | 100 – 150 |
| Neoprene Rubber | 100 – 150 | 250 – 400 |
| Expanded Polystyrene | 30 – 60 | 2 – 5 |
Neoprene rubber boasts impressive elongation capabilities but falls short in terms of tensile strength compared to ZF-22. Silicone foam provides similar tensile strength but lacks the elasticity needed for vibration damping. EPS, despite its light weight, is extremely brittle and unsuitable for dynamic load-bearing applications.
Cost Considerations
| Material | Average Cost per Cubic Meter ($) | Price Advantage (%) vs ZF-22 |
|---|---|---|
| Silicone Foam | $200 – $400 | +100% to +300% more expensive |
| Neoprene Rubber | $150 – $300 | +50% to +200% more expensive |
| Expanded Polystyrene | $20 – $50 | -80% to -95% cheaper |
While EPS is significantly cheaper, its limitations in performance outweigh the cost savings. Silicone foam and neoprene rubber, though offering certain advantages, come at a premium price that often makes them impractical for large-scale aerospace projects.
Environmental Impact
| Material | Recyclability (%) | Biodegradability (%) |
|---|---|---|
| Silicone Foam | 20 – 30 | 0 |
| Neoprene Rubber | 10 – 20 | 0 |
| Expanded Polystyrene | 50 – 70 | 0 |
ZF-22 scores higher on recyclability and biodegradability scales compared to silicone foam and neoprene rubber, aligning better with modern sustainability goals. EPS, while more recyclable, poses challenges in terms of microplastic pollution.
In summary, while each material has its strengths, polyurethane soft foam ZF-22 emerges as the optimal choice for aerospace applications due to its balanced performance across multiple criteria.
