Obvious change in melt flowability of modified transparent ABS (methyl methacrylate-acrylonitrile-butadiene-styrene copolymer)
Problem Phenomenon
Melt flowability of modified transparent ABS (methyl methacrylate-acrylonitrile-butadiene-styrene copolymer) changes obviously (better or worse), affecting the processing window
Cause Analysis
Additives change melt viscosity
Excessive addition amount, excessive flowability change
Uneven additive dispersion, local viscosity fluctuation
Processing temperature does not match the modified material
Improper lubricant addition
Solution
Adjust processing parameters to match the modified flowability
Reasonably control additive addition amount
Ensure uniform additive dispersion
Adjust temperature according to the modified material
Use lubricants reasonably
Key Takeaway
Flowability changes need process adjustment to match the modified material
