Substandard Flame Retardant Grade of Modified Acrylate-Epoxy-Phosphate-Distyrene Copolymer
Problem Phenomenon
The flame retardant grade of modified acrylate-epoxy-phosphate-distyrene copolymer is substandard, and the vertical burning or horizontal burning test fails to pass the target grade
Cause Analysis
The flame retardant addition amount is insufficient
The flame retardant has poor compatibility with the acrylate-epoxy-phosphate-distyrene copolymer and uneven dispersion
The flame retardant decomposes and fails at the processing temperature
The flame retardant system design is improper
The processing temperature is too high and the flame retardant degrades
Solution
Increase the flame retardant addition amount
Select a flame retardant with good compatibility
Select a flame retardant that is stable within the processing temperature range
Optimize the flame retardant system design
Control the processing temperature to avoid flame retardant degradation
Key Takeaway
Flame retardancy needs to be addressed from the addition amount, compatibility, and system design
