Product Description
The subsea buoyancy material is primarily used underwater. With its low density and high pressure resistance characteristics, it provides 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 parts.
This material not only meets the mechanical requirements of product structures but also significantly reduces product weight. It enables functions that are difficult to achieve with metal structural parts. Currently used in underwater deep submersibles and underwater robots, it can operate safely at depths of several thousand meters.

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 polyurethane-epoxy resin rigid foam composite material made by the chemical foaming method.
