Unstable Melt Index of PCTG
Problem Phenomenon
The MFI of different batches of PCTG raw materials differs greatly.
Cause Analysis
The molecular weight distribution differs between raw material production batches, and the supplier's production fluctuates.
Solution
Inspect the MFI at factory entry; establish MFI specification standards with the supplier; fine-tune the process according to MFI differences.
Key Takeaway
PCTG batch consistency is the basis of stable production.
