Professional Offshore Solid Buoyancy Modules Solution from the surface to subsea 7000msw. 

We provide the highest quality flotation for offshore, research, commercial. Made with syntactic foam, these floats are the most reliable and cost-effective choice for ROV, AUV, and tow body flotation. Whether you are outfitting a new vehicle or tooling package, or require customized add-on buoyancy, you will get a superior product and quick turnaround.

We provide a comprehensive range of resilient foam buoys products with advance solid buoyancy material production and polymer engineering. 

Our offshore buoyancy buoys generally consist of a closed-cell foam core encapsulated with tough, resistant polyurethane outer skin, combined with high-quality steelwork. We can make subsurface mooring buoys, cable floats, pipeline floaters, ROV buoyancy modules, special shape buoys, and other syntactic foam products. The out skin can be made by polyethylene shell and polyurethane elastomer.  

The subsea solid buoyancy material (syntactic foam) is a solid compound obtained by filling an organic polymer material with an inorganic light-weight filler material through a physical and chemical reaction. The deep-sea buoyancy material is a low-density, high-strength porous structure material. It is a counterweight material for underwater operation equipment.

The subsea buoyancy module is a polymer-based solid material with low density, high strength, and low water absorption. It has the characteristics of low density (0.35~0.7g/cm3), low water absorption ( ≤2%), high mechanical strength (compressive strength 1~100MPa), corrosion resistance, and secondary mechanical processing.

The solid buoyancy modules can meet the requirements of different underwater applications. An underwater system made of high-performance solid buoyancy materials. Not only can it dive to greater depths, increase the payload, and reduce energy consumption. And it can maintain a stable working condition underwater. Deep-sea solid buoyancy materials are an indispensable part of deep diving technology in the 21st century.

Subsea Buoyancy Syntactic Foam
Subsea solid buoyancy material (syntactic foam) is a lightweight composite formed by embedding hollow microspheres in polymer matrices. These low-density (0.35-0.7g/cm³), high-strength (1-100MPa) materials feature minimal water absorption (<2%) and corrosion resistance, serving as essential counterweights for underwater equipment. Their applications enable deeper dives, increased payload capacity, and stable operation in deep-sea environments, making them crucial for 21st-century subsea technology.
Chemical Foaming Solid Buoyancy Material
The chemical foaming method buoyancy material is a kind of polyurethane-epoxy resin rigid foam composite material made by the chemical foaming method.
