Product Description

Customized High Pressure Resistance Deep-sea Mining Buoyancy Modules CNC Precision Solution Buoy Systems
High-density, low water absorption floats designed for demanding subsea environments. Most products are custom manufactured to meet specific project requirements.

Subsea solid buoyancy material (syntactic foam) is a lightweight composite formed by embedding hollow microspheres in polymer matrices.
  • Low density (0.35-0.7g/cm³) Low density: Its density is far lower than that of water, which is key to providing buoyancy.
  • High strength (1-100MPa) :  Capable of withstanding all-around hydrostatic pressure in marine environments
  • Minimal water absorption (<1%):   it provides stable buoyancy under high water pressure, ensuring safe and reliable operation.
  • Excellent corrosion resistance :   It is resistant to deep sea water corrosion and has good weather resistance.
Engineered for Extreme Deep-Sea Environments

Our high-performance syntactic foams are specifically designed for deep-sea applications, offering:
These subsea buoyancy composites are typically fabricated by lightweight fillers like hollow glass microspheres to reduce density, often combining reinforcing fibers (e.g., carbon fiber, glass fiber) with polymer matrices (e.g., polyurethane, epoxy resin).

Applications
Our buoyancy modules are widely used in:
  • Manned submersibles
  • ROV/AUV buoyancy systems
  • Subsea oil and gas pipelines
  • Deep-sea mining equipment
By reducing structural weight while enhancing durability, our syntactic foams extend equipment lifespans and improve energy efficiency in marine operations.
