Offshore Marine Buoys Subsea Syntactic Foam Floats For Rov, Auv
Flotation ODM/OEM
High-density, low water absorption floats designed for demanding
subsea environments. Most products are custom manufactured to meet
specific project requirements.
Subsea Buoyancy Syntactic Foam
Subsea solid buoyancy material (syntactic foam) is a lightweight
composite formed by embedding hollow microspheres in polymer
matrices. These materials feature:
- Low density (0.35-0.7g/cm³)
- High strength (1-100MPa)
- Minimal water absorption (<2%)
- Excellent corrosion resistance
Engineered for Extreme Deep-Sea Environments
Our high-performance syntactic foams are specifically designed for
deep-sea applications, offering:
- Lightweight construction
- Exceptional strength-to-weight ratio
- Superior corrosion resistance
- Ultra-high pressure resistance (withstands depths exceeding 10,000
meters)
These advanced composites utilize lightweight fillers like hollow
glass microspheres combined with reinforcing fibers (carbon fiber,
glass fiber) and polymer matrices (polyurethane, epoxy resin) for
optimal performance.
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.
