Schuimfilms

Schuimfilms, also known as foam films or foam sheets, are thin, flexible materials made from expanded polymers. They are created by introducing gas into a molten polymer during the extrusion process, causing it to expand and form a cellular structure. This structure is typically closed-cell, meaning the gas bubbles are enclosed within the polymer walls, which contributes to the material's insulating and cushioning properties.

The most common polymers used for schuimfilms are polyethylene (PE) and polypropylene (PP), though other materials like polystyrene (PS) can also be employed. The density, thickness, and cell size of schuimfilms can be varied to achieve specific properties such as shock absorption, thermal insulation, and buoyancy. These films are lightweight yet possess good mechanical strength.

Schuimfilms find widespread application across various industries. In packaging, they are used to protect fragile items during transit due to their excellent cushioning capabilities. They are also utilized in the construction industry for thermal and acoustic insulation. Furthermore, schuimfilms are employed in the automotive sector for interior components and in the sporting goods industry for protective gear. Their versatility and cost-effectiveness make them a popular choice for many applications.
