The buoyancy of EPS (Expanded Polystyrene) foam is due to its closed-cell structure and the trapped air within those cells. The closed-cell structure prevents water from permeating the foam, allowing it to maintain its buoyant properties.
When EPS foam is used in applications requiring buoyancy, such as in floatation devices or marine structures, it displaces an amount of water equal to its weight. The trapped air within the closed cells provides buoyant force that opposes the force of gravity acting on the foam.
The buoyancy of EPS foam is determined by its density. EPS foam with lower density will have higher buoyancy because it has a larger volume of trapped air in proportion to its mass. Higher density foam will have lower buoyancy because it has a smaller volume of trapped air relative to its mass.
EPS foam is designed and manufactured with specific densities by EPS molding machine to provide the desired buoyancy for different applications. By controlling the density of the foam, manufacturers can tailor its buoyancy characteristics to meet specific requirements, whether it’s for floatation devices, marine structures, or other buoyancy-related applications.
It is important to note that the maximum buoyancy of EPS foam is limited, and it may not be suitable for applications requiring extreme buoyancy or heavy loads. In such cases, other materials or specialized buoyancy solutions may be more appropriate.
Need to note that these floats can be crushed by heavy duty EPS crusher machine with two rotors.
