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:

1. 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℃)

2. PEG Grafting Encapsulation

   • PEG-6000 grafted onto APP isolates antimony trioxide from moisture, cutting amine emissions by 92% after humidity aging

3. Performance Benchmark

Supply Chain Upgrade: Bio-Based Scavengers

• Pain Point: Petroleum-based DCPD scavengers surged 65% in 2025

• Kingfa Solution:
  ▶ Limonene from lactic acid fermentation (Jiangnan University collab)
  ▶ 51% bio-content, 40% better aldehyde adsorption
  ▶ 28% cost reduction, adopted in BYD Seal interiors

OEM Certification Milestones

1. Volkswagen ID.7 Project:

   • Passed 10 extreme tests (odor remains 3.1 after 1000h at 85℃/85%RH)

   • Secured $550M order, covering 70% of VW’s 2026 PP retardant demand

2. Geely Galaxy E8:

   • Dashboard TVOC=42μgC/g (industry lowest), certified "Zero Aldehyde" by CATARC

Future Strategy: AI Odor Prediction

• "Odor Genome Database" with CAS:
  ▶ 387 flame retardant decomposition fingerprints
  ▶ AI predicts odor levels, cutting R&D time 50%

• TÜV Rheinland certified 91.3% prediction accuracy
