Core Trend: Cabin Health Demands Odorless Flame Retardants
Mandatory Automotive Interior Odor Standard (July 2025) requires:
Odor level ≤3.5 for PP parts (vs. ≤4.5 legacy)
TVOC <50μgC/g (vs. 100μgC/g)
UL94 V-0 maintained
Per CAAM, NEV interior PP consumption hits 2.4M tons in 2025 (+38% YoY). Traditional bromine-antimony retardants emit fishy odors (trimethylamine decomposition), causing 63% OEM complaints.
Tech Breakthroughs: Dual-Path Odor Elimination
Kingfa OdorLess™ FR-8150 Innovations:
- Molecular Sieve Targeting
ZSM-5 nano-cages (0.55nm pores) capture trimethylamine (0.42nm), reducing odor from 4.8 to 2.7 (VDA 270 at 40℃)
- PEG Grafting Encapsulation
PEG-6000 grafted onto APP isolates antimony trioxide from moisture, cutting amine emissions by 92% after humidity aging
