Closed-Cell Foam

Closed-cell foam is a type of foam that is characterized by encapsulated, sealed air pockets that are dispersed throughout the material. This structure creates a dense, firm foam that has great insulation properties and is resistant to water and other fluids. Its solid cell structure gives it many benefits, including higher rigidity, higher compressive strength, excellent thermal and acoustic insulation, and superior resistance to chemicals and water penetration compared to open-cell foams. It is used in a wide variety of applications, including insulation for buildings and appliances, flotation devices, automotive parts, sports equipment, and many more. Popular types of closed-cell foam include polyethylene foam, EVA foam, and polystyrene foam.
