Description
Custom ROV buoyancy, umbilical and riser buoyancy, mid water arches deep water subsea buoyancy modules
High-density, low water absorption floats designed for demanding subsea environments. Most products are custom manufactured to meet specific project requirements.
The subsea solid buoyancy material 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.
High Density ROV Buoyancy , Umbilical And Riser Buoyancy Modules OEM OEM
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.
  • Low density (0.35-0.7g/cm³)
  • High strength (1-100MPa)
  • Minimal water absorption (<2%)
  • Excellent corrosion resistance
Engineered for Extreme Deep-Sea Environments
High Density ROV Buoyancy , Umbilical And Riser Buoyancy Modules OEM OEM
Our high-performance syntactic foams are specifically designed for deep-sea applications, offering:
  • Lightweight construction
  • Exceptional strength-to-weight ratio
  • Superior corrosion resistance
  • Ultra-high pressure resistance (withstands depths exceeding 10,000 meters)
These subsea buoyancy composites are typically fabricated by lightweight fillers like hollow glass microspheres to reduce density, often combining reinforcing fibers (e.g., carbon fiber, glass fiber) with polymer matrices (e.g., polyurethane, epoxy resin).
Applications
Our buoyancy modules are widely used in:
  • Manned submersibles
  • ROV/AUV buoyancy systems
  • Subsea oil and gas pipelines
  • Deep-sea mining equipment
By reducing structural weight while enhancing durability, our syntactic foams extend equipment lifespans and improve energy efficiency in marine operations.

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.
