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