Obvious Change in Melt Flowability of Acrylate-Epoxy-Phosphate-Distyrene Copolymer After Modification
Problem Phenomenon
The melt flowability of the acrylate-epoxy-phosphate-distyrene copolymer changes obviously (becomes better or worse) after modification, affecting the processing window
Cause Analysis
The added additives change the melt viscosity
The addition amount is too large, and the flowability change is excessive
The additives are unevenly dispersed, and the local viscosity fluctuates
The processing temperature does not match the modified material
The lubricant is added improperly
Solution
Adjust the processing parameters to match the flowability after modification
Reasonably control the additive addition amount
Ensure the additives are uniformly dispersed
Adjust the temperature according to the modified material
Use the lubricant reasonably
Key Takeaway
The flowability change needs to adjust the process to match the modified material
