CEF flame retardant effect not up to standard
Problem Phenomenon
The flame retardant grade of the CEF product is V-2 or not graded
Cause Analysis
The amount of flame retardant added is insufficient; the flame retardant has poor compatibility with CEF and is unevenly dispersed; the flame retardant decomposes and fails during processing
Solution
1) Increase the flame retardant to the recommended amount 15-25wt%; 2) Select a CEF special flame retardant to ensure compatibility; 3) Masterbatch method of flame retardant to ensure uniform dispersion
Key Takeaway
Flame retardant not up to standard is caused by insufficient amount and poor compatibility; increasing the amount and special flame retardant are the key
