Cellular polyethylene
Polyethylene foam, or PE foam for short, is a versatile and widely used material that impresses with its remarkable combination of lightness and robustness. PE foam offers excellent insulating properties, is moisture resistant and chemical resistant, making it ideal for a wide range of applications including packaging, construction and automotive. Thanks to its flexibility and shock-absorbing capacity, PE foam protects sensitive products and contributes to energy efficiency in buildings. These properties make it an indispensable material in many industrial sectors.

PE foam
- Cellular polyethylene
- Closed-cell material with good mechanical properties and low density, excellent resistance to weathering and ageing, good sound insulation, good thermal insulation and very good resistance to commercially available acids, alkalis and other chemicals.
Non-crosslinked foams
- The long carbon-hydrogen chains that make up PE foam are not connected or cross-linked. As a result, non-crosslinked foams have a very defined melting point at which the carbon-hydrogen chains separate from each other. Plasticization occurs at this temperature (thermoplastic).
EVA foam
- Mixed polymer foam that is characterized by its low compression set.
Chemically cross-linked foams
- The hydrocarbons that make up the PE foam are chemically bonded together to form chains. Cross-linking increases the thermal stability. This creates a melting area (thermal load).
Physically cross-linked foams
- In contrast to chemical cross-linking, the cross-linking is generated by a high-energy electron beam field. However, this is only possible with thin foams (sheet material).
