PETG and PC blending insufficient compatibility
Problem Phenomenon
When PETG and PC are mechanically blended, delamination and phase separation occur, and the mechanical properties are lower than expected.
Cause Analysis
PETG and PC are partially compatible but phase-separate at specific ratios, and the blending process parameters are insufficient to achieve good dispersion.
Solution
Use a compatibilizer (acrylate copolymer); optimize the twin-screw process; control the blending ratio within the compatibility window.
Key Takeaway
PETG/PC alloy preparation requires the dual guarantee of compatibilizer and process.
