Floating solar power generation is rapidly emerging as an alternative technology to land-based solar power generation around the world, and there are many advantages to developing and operation floating solar power, but it is a buoyant body that floats solar power modules and structures such as typhoons, tsunami, and wave heights. Research and development is actively underway, and in particular, as damage to buoyancy bodies, which is a vulnerability of floating solar power generation facilities, has been highlighted as a cause of eco-friendly(EVA) buoyancy bodies to improve buoyancy excellence was also achieved in various aspects such as resilience, environmental friendliness, maintenance, and durability.

As the results of study, physical characteristics of light weight buoyancy material improve as MMA content was increased. When considering density and abrasion properties of light weight buoyancy, the proper mixing condition is thought to be C1.0.
