Polymeerivaahdot

Polymeerivaahdot, or polymer foams, are cellular materials produced from polymers. They consist of a solid polymer matrix with a large number of gas-filled voids. These foams can be rigid or flexible, depending on the polymer used and the foaming process.

The creation of polymer foams involves expanding a polymer material, typically by introducing a blowing agent. This agent can be physical, such as a gas or a volatile liquid that vaporizes during processing, or chemical, where a chemical reaction generates gas. The expansion process creates the characteristic cellular structure.

Polymeerivaahdot find widespread applications across various industries due to their unique properties. Their low density makes them excellent for insulation, both thermal and acoustic. In the automotive and aerospace sectors, they are used for weight reduction, impact absorption, and structural components. The packaging industry utilizes them for cushioning and protection of goods. Furthermore, they are employed in furniture, footwear, and construction as filling or structural materials. The specific properties, such as strength, flexibility, and insulating capabilities, can be tailored by selecting different polymers and controlling the foaming parameters.
