Product Description
Our subsea buoyancy material is engineered for underwater applications, offering low density and high pressure resistance to provide essential buoyancy for underwater operation equipment. The surface can be treated with spray coating or protective layers as required. These materials are commonly manufactured into floats, buoys, and other counterweight products, or directly machined into product components.
Key Benefits
- Meets structural mechanical requirements while significantly reducing product weight
- Enables functions difficult for metal structural parts to achieve
- Proven in underwater deep submersibles and robots
- Safe operation at depths of several thousand meters
Subsea Buoyancy Syntactic Foam
Our 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%), and excellent corrosion resistance. They serve as essential counterweights for underwater equipment, enabling deeper dives, increased payload capacity, and stable operation in deep-sea environments.
Chemical Foaming Solid Buoyancy Material
The chemical foaming method buoyancy material is a polyurethane-epoxy resin rigid foam composite made by chemical foaming process.
