Flame retardant grade of modified styrene-butadiene transparent resin (K resin) not up to standard
Problem Phenomenon
Flame retardant grade of modified styrene-butadiene transparent resin (K resin) is not up to standard; vertical burning or horizontal burning tests fail to pass the target grade
Cause Analysis
Insufficient flame retardant addition amount
Poor compatibility between flame retardant and styrene-butadiene transparent resin (K resin), uneven dispersion
Flame retardant decomposes and fails at processing temperature
Improper flame retardant system design
Processing temperature too high, flame retardant degrades
Solution
Increase flame retardant addition amount
Select flame retardants with good compatibility
Select flame retardants stable within the processing temperature range
Optimize flame retardant system design
Control processing temperature to avoid flame retardant degradation
Key Takeaway
Flame retardancy needs to start from addition amount, compatibility, and system design
