Interlayer Delamination in PCTG Co-Extrusion
Problem Phenomenon
Interlayer separation occurs when PCTG is co-extruded with other materials.
Cause Analysis
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.
Solution
Use adhesive layer resin; optimize the temperature of each layer to match the viscosity; select compatible material combinations.
Key Takeaway
The interfacial bonding of PCTG co-extrusion depends on material and process matching.
