Interlayer Delamination in PCTG Co-Extrusion
Problembeschreibung
Interlayer separation occurs when PCTG is co-extruded with other materials.
Ursachenanalyse
The compatibility between the materials is insufficient, the melt temperatures of the layers do not match, resulting in viscosity differences, and no adhesive layer is used.
Lösung
Use adhesive layer resin; optimize the temperature of each layer to match the viscosity; select compatible material combinations.
Wichtigste Erkenntnis
The interfacial bonding of PCTG co-extrusion depends on material and process matching.
