Open Cell Metal Foam

Open cell metal foam, also known as reticulated foam, features 100% open cells with a homogenous structure. The open cells provide a path through the foam in any direction, allowing gas and liquids to pass at control flow rates and buffer pressure. Open foams have high surface area-to-volume ratios which offer large heat transfer rates. They are lightweight, with high compressive strength, stiffness, energy absorption, and low specific weight. Specific properties and applications vary based on foam material.

The most popular open-cell metal foam products are Aluminum and RVC foam.

Sustainable Qualities

Open Cell Metal Foam is considered sustainable because it is made from recycled metals and is fully recyclable at the end of its lifecycle. It also has a high strength-to-weight ratio, which can reduce material usage and transportation emissions. Its unique porous structure also allows for improved heat and sound insulation, potentially reducing energy consumption in various applications. As a recyclable and energy-efficient material, Open Cell Metal Foam can contribute to a circular economy by reducing waste and promoting sustainable resource use.
