Interlayer Delamination in PCTG Co-Extrusion
문제 현상
Interlayer separation occurs when PCTG is co-extruded with other materials.
원인 분석
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.
해결 방법
Use adhesive layer resin; optimize the temperature of each layer to match the viscosity; select compatible material combinations.
핵심 요약
The interfacial bonding of PCTG co-extrusion depends on material and process matching.
