Deepwater Buoyancy Materials

The ocean, which covers 70% of the Earth's surface, contains vast amounts of resources and minerals. Since the 21st century, various countries have invested a great deal of manpower and resources in ocean engineering. Activities such as ocean surveys, explorations, and developments have gradually shifted from shallow seas to deep seas.
Buoyancy materials are an important part of modern deep - diving technology. The performance requirements of various equipment for buoyancy materials have also increased significantly. High - performance and high - strength solid buoyancy materials are an essential component of modern deep - diving technology. They are generally made of epoxy resin and hollow microspheres.
From the late 1980s to the early 1990s, we successively undertook and completed the development work of "light - weight epoxy materials" for Shenyang Chemical Plant and "buoyancy equipment for deep - sea robots" for the Institute of Automation, Chinese Academy of Sciences. Subsequently, we developed a series of products with different densities.
The buoyancy materials developed by our company can be widely used in civilian, commercial, and military fields, such as deep - sea buoyancy materials, aerospace materials, offshore exploitation, wind turbine blades, floating cities or islands, etc.
