EMA flame retardancy not up to standard
Problem Phenomenon
EMA product flame retardant rating V-2 or unrated
Cause Analysis
Insufficient flame retardant addition; poor compatibility between flame retardant and EMA causing uneven dispersion; flame retardant decomposes and fails during processing
Solution
1) Increase flame retardant to recommended dosage 15-25wt%; 2) Select EMA-dedicated flame retardant to ensure compatibility; 3) Use flame retardant masterbatch method to ensure uniform dispersion
Key Takeaway
Flame retardancy failure is caused by insufficient dosage and poor compatibility; increasing dosage and dedicated flame retardant are key
