MP large compression set

Problembeschreibung

MP product compression set >30%, below the 15% requirement

Ursachenanalyse

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

Lösung

1) increase crosslinking degree to 60-70% to reduce plastic deformation; 2) select a high elastic recovery MP grade; 3) add reinforcing filler

Wichtigste Erkenntnis

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