Properties & Performance
FAQ category
Technical characteristics and performance of cross-linked and non-crosslinked PE foam: density, compression resistance, water absorption, temperature limits and durability in real operating conditions. Practical answers for engineers, installers and purchasing teams.
- Density & compression: stability under load, permanent deformation.
- Resistance: water, temperature, vibration and aggressive environments.
- Durability: long-term behaviour, UV and service life.
IXPE/XPE foams are normally 25–200 kg/m³, while non-crosslinked PE grades (Warmlex) range 18–45 kg/m³.
