Polyethylene Foam
Polyethylene foam, also referred to as PE, is a type of foam that is very rigid and made primarily through an extrusion process. Polyethylene foam is a strong, resilient, closed-cell type of foam. Polyethylene foam, unlike polyurethane foam, has the capability of being reheated in order to change its shape. Polyethylene foam is lightweight, flexible, cost-effective, and resilient to mildew, mold, rot, bacteria, and breakage. Also, because polyethylene foam is CFC-free, recyclable, and odorless, it provides an environmentally-friendly solution.
Polyethylene foam is produced through the polymerization of ethylene. Polyethylene foam is made up of huge chains of ethylene that stick together through weak forces, meaning the polyethylene foam material can be broken apart by human hands. Polyethylene foam has different densities and the material properties can vary as created by using different catalysts during the polymerization process.
While its most popular use is as cushioning for products in packaging applications, polyethylene foam is also commonly used for shock absorbing, vibration dampening, insulation, cushioning, and loose fill. Other useful applications of polyethylene foam can be found in the appliances, aerospace, packaging, and flotation industries. Due to its buoyancy, polyethylene foam is also useful for nautical purposes.
