Professional Offshore Solid Buoyancy Modules Solution from the surface to subsea 7000msw.
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.
Material Advantages
Syntactic Foam
Syntactic foams are composite materials synthesized by filling a metal, polymer, or ceramic matrix with hollow spheres called micro balloons or cenospheres or non-hollow spheres

Syntactic Foam Subsea Buoyancy Products
The subsea buoyancy material is mainly used underwater. Based on its characteristics of low density and high-pressure resistance, it mainly provides the required buoyancy for underwater operation equipment. Spray coating or protective layer treatment can be applied to the surface as required. Often manufactured and processed into floats, buoys, and other counterweight products. It can also be directly machined into product parts. It can not only meet the mechanical requirements of the product structure but also greatly reduce the product weight and other functions. The application of this material realizes the functions that are difficult for metal structural parts to realize. At present, it has been used in underwater deep submersibles, underwater robots, etc., and can be used safely at depths of several thousand meters underwater. |  |
