PC/ABS flame retardant grade not up to standard
Problem Phenomenon
Flame retardant PC/ABS cannot reach V-0 grade.
Cause Analysis
Insufficient flame retardant system dosage or improper formulation; thin product walls cause heat accumulation during burning.
Solution
Optimize the flame retardant system (phosphorus-based + PTFE anti-dripping); ensure wall thickness ≥1.5mm.
Key Takeaway
PC/ABS flame retardancy requires comprehensive consideration of formulation and wall thickness.
