foamed thermoplastic

Foamed thermoplastics are a type of plastic that has been expanded to create a lightweight, cellular structure. This is achieved by incorporating a blowing agent, such as isopentane or nitrogen, into the molten thermoplastic. When heated, the blowing agent expands, creating gas bubbles within the plastic. This process results in materials with lower thermal conductivity and greater rigidity for their weight compared to solid polymers.12

Foamed thermoplastics are widely used in applications like home insulation and protective packaging due to their energy-absorbing properties. They can be formed into various shapes, from continuous sheets to rigid packaging and even furniture components, depending on the specific polymer and foaming method used. Common thermoplastics that can be foamed include polystyrene, polyethylene, and polypropylene.12
