Closed-cell polyethylene (PE) foam is a versatile synthetic material characterized by its fine cellular structure with >90% closed cells. This lightweight, resilient foam offers excellent resistance to water, chemicals, and weather conditions. Available in multiple densities and thicknesses, it provides effective thermal insulation, vibration damping, and serves as an ideal material for expansion joints, gaskets, and sill plates in construction applications.

- Tensile strength
- 483 kPa For 64 kg/m³ density. Source: ASTM D3575
- Compressive strength
- 90 kPa At 25% deflection for 64 kg/m³ density. Source: ASTM D3575
- Flexural strength
- Not a primary design criterion; flexural modulus 2000-4000 kPa at 64 kg/m³ kPa Closed-cell PE foam has low flexural stiffness by design; bending resistance is characterised by flexural modulus rather than ultimate flexural strength. For 64 kg/m³ density, flexural modulus approximately 2000-4000 kPa and the material fails gradually in bending without a distinct fracture point. Not typically a design parameter for gasket/joint applications. Source: ASTM D3575 Method W; Sekisui Alveo Stratocell technical data; Sealed Air Ethafoam product bulletin.
