Narrow Melt Temperature Control in LCP '2079851475616104452
Problem Phenomenon
The LCP processing temperature window is narrow (330-390°C), and rapid degradation occurs above 390°C.
Cause Analysis
The LCP liquid crystal phase only forms in a specific temperature range; if too low, the liquid crystal phase is insufficient, and if too high, it decomposes.
Solution
Precise temperature control ±3°C; staged heating ensures uniform melting; avoid excessively long residence time.
Key Takeaway
Precise control of the LCP temperature window is quality assurance.
