Scattered PLA heat distortion temperature test values
Problembeschreibung
The HDT test values of PLA products with the same formulation are widely scattered.
Ursachenanalyse
Uneven crystallinity leads to HDT differences, and the test samples have different heat histories.
Lösung
Standardize and unify sample preparation and treatment; fully crystallize.
Wichtigste Erkenntnis
The HDT dispersion of PLA is related to the crystallinity difference.
