LD series solid buoyancy material

Lightweight and pressure resistant full sea depth buoyancy solution

The LD series solid buoyancy material is an epoxy based glass bead composite material developed by our joint research institute, which has excellent properties such as high strength, low density, low water absorption, and easy processing. The product covers applications from water surface to full sea depth of 11000 meters, with adjustable density in the range of 0.36-0.63 g/cm ³, compressive strength of 8-85 MPa, water absorption rate ≤ 1%, and can provide stable and reliable net buoyancy for various underwater operation platforms. The company has a complete set of CNC machining centers and polyurea spraying equipment, and can customize products such as shaped floats, floating balls, and floats according to customer needs. They have been widely used in well-known underwater robot companies, marine universities, and research institutions at home and abroad.
