Interlayer Delamination in PCTG Co-Extrusion
Fenómeno do problema
Interlayer separation occurs when PCTG is co-extruded with other materials.
Análise das causas
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.
Solução
Use adhesive layer resin; optimize the temperature of each layer to match the viscosity; select compatible material combinations.
Conclusão principal
The interfacial bonding of PCTG co-extrusion depends on material and process matching.
