Polyeteenivaahdot, often referred to as polyethylene foams, are versatile cellular materials produced from polyethylene. These foams are characterized by their closed-cell structure, which gives them excellent properties such as low density, good thermal insulation, buoyancy, and shock absorption.

The manufacturing process typically involves the expansion of polyethylene using a blowing agent. This can be achieved through various methods, including extrusion, molding, or bead foaming. The density of polyethylene foams can be significantly reduced compared to solid polyethylene, making them lightweight and cost-effective for numerous applications.

Polyethylene foams are widely used across diverse industries. In the packaging sector, they provide cushioning and protection for fragile items during transit. Their excellent thermal insulation properties make them suitable for construction applications, such as insulating pipes and walls, as well as in refrigeration and HVAC systems.

Due to their buoyancy, these foams are employed in flotation devices, life jackets, and marine applications. The shock-absorbing capabilities of polyethylene foams also lend themselves to sports equipment, protective padding, and automotive components. They are also utilized in the medical field for prosthetics and packaging of sensitive medical devices.

Polyethylene foams are generally resistant to moisture, chemicals, and UV radiation, contributing to their durability and longevity in various environments. They can be manufactured in a range of densities, cell structures, and flexibility to meet specific performance requirements.
