PVC foam board is a lightweight, strong and durable material commonly used in construction, advertising, furniture and other fields. It has high hardness and can withstand a certain amount of pressure and weight.
The hardness of PVC foam board mainly depends on its density and internal structure. The higher the density of the foam board, the greater the hardness. Generally speaking, the density of PVC foam board is between 0.3-0.8g/cm³, and the hardness is between 45-80. The higher density and hardness make PVC foam board have better compression resistance and can withstand greater weight and pressure.
In addition, the internal structure of PVC foam board will also affect its hardness. There are many small bubbles inside the foam board, which can reduce the weight of the material, but also reduce its hardness. Therefore, the hardness of PVC foam board is related to the size and distribution of bubbles inside it. Generally speaking, the smaller and evenly distributed the bubbles, the greater the hardness.
The hardness of PVC foam board is of great significance to its use. The higher hardness allows PVC foam board to withstand greater pressure and weight, is not easy to deform and break, and can protect the pattern and color of its surface to a certain extent. Therefore, PVC foam boards are often used to make billboards, display racks, furniture and other products that need to withstand a certain amount of pressure and weight.
In short, PVC foam board has high hardness and can withstand a certain amount of pressure and weight. Its hardness mainly depends on density and internal structure. Higher density and evenly distributed bubbles can increase its hardness. The hardness of PVC foam board makes it an ideal material and is widely used in construction, advertising, furniture and other fields.
