Melt index differences between batches of PAR raw materials
Problem Phenomenon
The melt index of high-heat-resistant PAR fluctuates greatly between different batches.
Cause Analysis
The molecular weight control fluctuates during PAR synthesis, causing melt index differences.
Solution
Strictly control the melt index range in the incoming material standard; process parameters can be fine-tuned.
Key Takeaway
PAR batch consistency is crucial for precision molding.
