Foam is all around us in everyday items such as mattresses, pillows, and patio cushions. However, not all foam is created equal and choosing the right type of foam for your application can make a difference in your product performance, durability, and cost. Foams come in many different thicknesses and densities with a variety of anti static or fire retardant options to meet specific requirements for your project. Reads more https://a1insulation.com/

The main types of foam include open, closed, and elastomeric. Open-cell foams, such as the kind most people are familiar with in memory foam mattresses and furniture, are characterized by large cells left deliberately open at a molecular level. This makes these types of foam lighter and softer, with a flexibility that allows air and liquid to pass through them easily. Closed-cell foams, on the other hand, are densely bonded together and have tightly sealed cells. This creates a stiffer but generally less rigid foam that is impervious to air and water, making it the most ideal packaging material for heavy products and cushioning applications that require high levels of durability and protection.

Choosing Between Foam Types: Open-Cell vs. Closed-Cell Explained

Knowing the differences between these foams is crucial for proper packaging and protective cushioning applications. A number of tests, including tensile strength and cushioning curves, are available to gauge the durability of your chosen foam. Tensile strength testing (ASTM D-3574-17) gives you numerical results that tell you how durable a piece of foam is when under pressure, while cushioning curves are an efficient way to assess the amount of resistance a specific foam type has when compressed.
