MP hardness too high
Problembeschreibung
MP product Shore hardness 5-10 degrees higher than the target, hard to the touch
Ursachenanalyse
MP crystallinity high, rigidity increased; filler added too much; cooling too fast, crystallization incomplete but rigidity frozen
Lösung
1) reduce cooling rate to complete crystallization and reduce the hard feel; 2) reduce filler addition; 3) add plasticizer 0.5wt% to lower hardness
Wichtigste Erkenntnis
high hardness is caused by crystallization and filler; adjusting cooling and filler are key
