Poor micro-foaming effect of products
Problembeschreibung
The cells of micro-foamed products are large and uneven
Ursachenanalyse
Blowing agent dispersion is uneven; gas solubility in the melt is insufficient; the pressure release rate does not match the foaming temperature
Lösung
Optimize pre-dispersion of the blowing agent in the blend; increase melt pressure to increase gas solubility; precisely control foaming temperature
Wichtigste Erkenntnis
Micro-foaming quality depends on precise control of nucleation and cell growth
