EEA Large Compression Set

Problembeschreibung

EEA product compression set >30%, lower than the 15% requirement

Ursachenanalyse

EEA elastic recovery insufficient; crosslinking degree low, plastic deformation unrecoverable; density low, cell walls thin, recovery poor

Lösung

1) Increase crosslinking degree to 60-70% to reduce plastic deformation; 2) Select high-elastic-recovery EEA grades; 3) Add reinforcing fillers

Wichtigste Erkenntnis

Large compression set is caused by insufficient crosslinking; increasing crosslinking degree is key
