PESchaum

PESchaum is a German-language term commonly used to refer to polyethylene foam, a family of closed-cell polymer foams made from low-density polyethylene (LDPE) or cross-linked polyethylene. It appears under several trade and technical names, including PE foam, EPE (expanded polyethylene) and XPE (cross‑linked polyethylene). PESchaum is produced by foaming polyethylene using physical or chemical blowing agents or by cross‑linking techniques such as irradiation or chemical agents to control cell structure and mechanical properties.

PESchaum is lightweight, resilient and buoyant, with low water absorption, good chemical resistance and effective thermal and acoustic insulation. Its closed-cell structure gives it cushioning and shock‑absorption characteristics, while its flexibility and compressive recovery make it suitable for repeated use. Densities and stiffness vary by grade, allowing use in soft protective packaging or firmer structural padding.

Common applications include protective packaging for electronics and fragile goods, sports and exercise mats, footwear components, automotive trim and vibration damping, floatation devices, pipe and building insulation, and reusable shipping inserts. Variants are available with adhesive backing, laminates, or surface treatments for fire performance.

Environmental considerations include recyclability as polyethylene and the persistence of petrochemical plastics; some grades incorporate flame retardants or additives that affect disposal options. PESchaum is subject to industry standards and specifications for physical properties, flammability and hygiene depending on application.
