AM3V: The Next-Generation Flame Retardant Replacing ATO in PVC Compounds
Advanced Aluminum Magnesium Layered Double Hydroxide (LDH) Flame Retardant for Next-Generation PVC Compounds
Introduction
As industries worldwide accelerate their transition toward safer, cost-effective, and environmentally sustainable flame retardant solutions, the demand for high-performance alternatives to Antimony Trioxide (ATO) has reached unprecedented levels. AM3V represents a groundbreaking advancement in flame retardant technology—an innovative aluminum and magnesium co-precipitated layered double hydroxide (LDH) specifically engineered to revolutionize fire safety standards in PVC compounds.
Developed by KMT Industrial's world-class R&D team, AM3V delivers superior flame retardancy, dramatically reduced smoke density, and substantial cost savings, making it the ideal ATO replacement for demanding applications across cables, construction materials, automotive components, and industrial equipment. By replacing traditional ATO+ATH/MDH blends with AM3V, manufacturers can achieve equivalent or superior performance while significantly reducing environmental impact and production costs.
Why AM3V Stands Out
AM3V leverages KMT Industrial's proprietary co-precipitation technology, a sophisticated synthesis process that enables nanoscale synergy between magnesium and aluminum hydroxide layers. This innovative approach creates a uniquely structured layered double hydroxide with exceptional flame retardant properties that far exceed traditional micron-level physical blends.
Advanced Co-Precipitation Technology
Unlike conventional flame retardant formulations that simply mix aluminum trihydrate (ATH) or magnesium dihydroxide (MDH) with ATO, AM3V's co-precipitation process creates a homogeneous molecular structure at the nanoscale. This results in:
- Optimized Al/Mg Ratio (7:3): Precisely engineered stoichiometry for maximum flame suppression efficiency
- Well-Defined Layered Structure: Uniform crystal morphology ensuring consistent performance
- Enhanced Intercalation Properties: Superior ability to trap and release water molecules during thermal decomposition
- Patented KMT Coating: Surface modification technology that improves dispersion and compatibility with PVC matrices
Superior Flame Retardancy
Achieves a Limited Oxygen Index (LOI) of ≥30%, matching or exceeding traditional ATO-based formulations while delivering enhanced char formation and drip prevention.
Dramatic Smoke Reduction
Up to 56% lower smoke density compared to ATO (28.34 vs. 64.51 in testing), critical for maintaining visibility and safety during fire emergencies in confined spaces.
Exceptional Cost Efficiency
Using 40 phr of AM3V delivers equivalent performance to 5 phr of ATO at approximately 1/15th the material cost, transforming the economics of flame retardant formulations.
Environmental Sustainability
Replaces traditional ATO+ATH/MDH blends with a non-toxic, heavy-metal-free alternative, aligning with global sustainability goals and evolving regulatory requirements.
Versatile Applications
Ideal for PVC compounds used in electrical cables, construction profiles, piping systems, automotive interiors, and industrial fire-sensitive environments.
Easy Integration
Compatible with existing PVC processing equipment and formulations, minimizing transition costs and production downtime during material switching.
Performance Comparison
Comprehensive testing on standardized PVC formulations demonstrates AM3V's significant advantages over traditional ATO and ATH (40CD) blends. The following data represents results from controlled laboratory conditions using identical base formulations to ensure fair comparison.
Key Performance Insights
Equivalent Flame Retardancy
40 phr AM3V matches the LOI performance of 5 phr ATO (both achieving 30%), ensuring robust fire resistance that meets international safety standards including IEC 60332, UL 94, and BS 5852.
Superior Smoke Suppression
AM3V reduces maximum smoke density by 56% compared to ATO (28.34 vs. 64.51), a critical advantage for maintaining evacuation visibility and reducing toxic exposure in fire scenarios.
Outstanding Cost Efficiency
AM3V's significantly lower material cost (approximately 1/15th of ATO) makes it a transformative solution for manufacturers seeking to reduce production costs without compromising safety standards.

Why Replace ATO?
Antimony Trioxide (ATO) has served as a cornerstone flame retardant synergist for decades, but mounting economic pressures, environmental concerns, and evolving regulatory landscapes are accelerating the industry's transition toward sustainable alternatives. AM3V addresses these challenges head-on.
Economic Pressure
ATO prices have experienced significant volatility, with costs often exceeding $8,000-12,000 per metric ton. AM3V offers dramatically lower material costs (approximately 1/15th of ATO) while delivering equivalent flame retardant performance, directly improving profit margins.
Environmental & Regulatory Concerns
ATO is classified as a Substance of Very High Concern (SVHC) under REACH regulations due to its classification as a suspected carcinogen. The EU's evolving regulations and global push toward safer alternatives make ATO replacement increasingly critical for market access.
Enhanced Safety Performance
With smoke being the primary cause of fatalities in fire incidents, AM3V's 56% smoke reduction compared to ATO provides superior protection for building occupants, emergency responders, and equipment in critical infrastructure applications.
Sustainability Leadership
Replacing ATO with AM3V supports corporate ESG (Environmental, Social, and Governance) goals and demonstrates commitment to sustainable manufacturing practices, increasingly important for B2B relationships and end-consumer preferences.
Supply Chain Security
ATO production is concentrated in a limited number of countries, creating supply chain vulnerabilities. AM3V's raw materials are more widely available, reducing geopolitical risks and ensuring more stable procurement.
Future-Proof Compliance
Proactively switching to AM3V positions manufacturers ahead of regulatory changes, avoiding costly reformulation deadlines and potential market exclusion as restrictions on ATO continue to expand globally.

Frequently Asked Questions
Based on testing and customer applications, AM3V is typically used at 35-45 parts per hundred resin (phr) to achieve equivalent flame retardancy to 5 phr ATO. The exact dosage depends on your specific formulation, target LOI requirements, and other performance parameters. Our technical team can provide formulation guidance tailored to your application.
AM3V is designed to balance flame retardancy with mechanical performance. While some adjustment to formulation may be needed compared to ATO systems, most customers find that standard PVC processing parameters and typical stabilizer packages work well with AM3V. The density advantage (1.46 vs 1.49 for ATO systems) can actually improve specific strength properties in some applications.
AM3V's optimized particle size (D50: 3.0-4.0 μm) and proprietary coating provide excellent dispersion and compatibility with PVC matrices. Processing temperatures and cycles are generally comparable to traditional ATH/MDH systems. The KMT coating technology minimizes moisture sensitivity and improves surface finish of finished products.
Yes, AM3V can be used in combination with other flame retardants including nano-clays, intumescent systems, and phosphorus-based additives. In fact, many customers achieve optimal results by combining AM3V with carefully selected complementary additives to fine-tune performance for specific requirements.
