High-performance hollow glass microspheres (HGM) have become a key material for overcoming the limitations of traditional technologies, thanks to their low density, low thermal conductivity, high compressive strength, and excellent dispersibility, flowability, and chemical stability.
HGM also offers excellent properties such as low dielectric constant, self-lubrication, sound insulation, water resistance, fire resistance, and corrosion resistance, enabling it to meet the operational requirements of various specialized and complex marine environments and drive the development of the marine economy.
HGM Empowers Solid Buoyancy Materials
Weight Reduction: Adding hollow glass microspheres to solid buoyancy materials can significantly reduce the material’s overall density, thereby achieving weight reduction.
Increasing Material Strength: By adjusting the content and distribution of hollow glass microspheres, the mechanical properties of buoyant solid materials can be improved, enabling them to withstand greater loads and stresses.
Energy Absorption and Vibration Damping: The distribution of hollow glass microspheres within solid buoyant materials can provide a certain degree of energy absorption and vibration damping.
HGM Empowers Deep-Sea Cables
Buoyancy Support: Deep-sea cables must be installed using underwater suspension or laying methods, and maintaining the cable’s buoyancy in the underwater environment is critical. Hollow glass microspheres can be added to the cable sheath or filler material to provide buoyancy support.
Elastic Shock Absorption: Adding hollow glass microspheres to the cable jacket provides a certain degree of elastic shock absorption. When the cable is subjected to external impacts or vibrations, the hollow glass microspheres absorb and disperse some of the impact energy, thereby reducing damage to the cable.
Pressure Resistance: Deep-sea environments are subject to high water pressure, and cables must be able to withstand this pressure. Filling the cable sheath with hollow glass microspheres enhances the cable’s structural strength and rigidity, enabling it to withstand high-pressure underwater environments and ensuring the cable’s integrity and reliability.
HGM Empowers Heavy-Duty Anti-Corrosion Coatings
Corrosion Resistance: Hollow glass microspheres are made of glass and offer excellent corrosion resistance. Adding hollow glass microspheres enhances the corrosion resistance of coatings, enabling them to perform reliably over the long term in marine environments.
Filling and Reinforcement: Hollow glass microspheres can be used as a filler, which helps enhance the coating’s adhesion and durability, making it more resistant to seawater erosion. Filling the coating with hollow glass microspheres also improves its impact resistance and abrasion resistance, reducing damage caused by external forces.
Lightweight: Hollow glass microspheres are a lightweight material; when added to marine heavy-duty anti-corrosion coatings, they help reduce the weight of the coating.
