The density of EVA foam sheet is a crucial factor that determines its physical properties and performance characteristics. The density of EVA foam is measured in kilograms per cubic meter (kg/m³) and indicates the weight of the foam material per unit volume.
The density of EVA foam sheet plays a significant role in its compressibility, stiffness, and durability. A higher density EVA foam sheet will generally exhibit improved stiffness and structural integrity, providing better support and durability under compression. On the other hand, a lower density EVA foam sheet will tend to be more compressible, offering better cushioning and conformability.
The density of EVA foam sheet can vary depending on the manufacturing process and配方specific formula used to create it. In general, the density of EVA foam sheet ranges from about 20 kg/m³ to 60 kg/m³, depending on the intended application.
For example, EVA foam sheets used in shoe insoles or floor mats typically have a lower density to provide good cushioning and conformability, while EVA foam sheets used in outdoor decking or seating may have a higher density for better durability and structural support.
When selecting an EVA foam sheet for a specific application, it is important to consider its density and other physical properties, such as tensile strength, tear resistance, and temperature resistance. These properties will help determine the suitability of the EVA foam sheet for the specific task and ensure it meets the required performance standards.
