Product Description
300M Deepwater Buoyancy Foam For Underwater Robot ROV AUV AOV
One of the key features of this material is its strong resistance to hydraulic pressure and its closed-cell structure.
This ensures that it has very low buoyancy loss and water absorption rate even under long-term load conditions.
In addition, it has excellent insulation performance. An important performance indicator is that when the initial
the volume of the material is reduced by 5%, the pressure size is measured in the bar.
Features
1. Excellent buoyancy performance
2. High-temperature resistance
3. High-impact resistance
4. Low water absorption
5. Thermoforming
6. Excellent damage tolerance
7. Good chemical corrosion resistance
This is Not suitable for long-term underwater work
