AM3V: The Next-Generation Flame Retardant Replacing ATO in PVC Compounds

Introduction

As industries worldwide seek safer, cost-effective, and eco-friendly flame retardant solutions, the demand for alternatives to Antimony Trioxide (ATO) is surging. KMT Industrial introduces AM3V, an innovative aluminum and magnesium co-precipitated layered double hydroxide (LDH) flame retardant designed to revolutionize fire safety in PVC compounds. With superior performance, reduced smoke density, and significant cost savings, AM3V is the ideal ATO replacement for applications in cables, construction, and beyond.

Why AM3V Stands Out

AM3V leverages KMT Industrial’s proprietary co-precipitation technology, enabling nanoscale synergy between magnesium and aluminum. Unlike traditional micron-level blends, AM3V’s optimized Al/Mg ratio (7:3) and well-defined layered structure deliver unmatched flame retardancy and smoke suppression. Coated with KMT’s patented technology, AM3V ensures exceptional performance in Fire-Retardant Low-Smoke (FRLS) PVC formulations.

Key Benefits of AM3V

High Flame Retardancy: Achieves a Limited Oxygen Index (LOI) of ≥30%, matching or exceeding ATO-based formulations.
Reduced Smoke Density: Up to 56% lower smoke density compared to ATO (28.34 vs. 64.51), enhancing safety in fire scenarios.
Cost-Effective: 40 phr of AM3V delivers equivalent performance to 5 phr of ATO at approximately 1/15th the cost, offering substantial savings.
Eco-Friendly: Replaces traditional ATO+ATH/MDH blends, aligning with the industry’s shift toward sustainable flame retardants.
Versatile Applications: Ideal for PVC compounds used in cables, construction materials, and other fire-sensitive environments.

Key Insights:

Equivalent Flame Retardancy: 40 phr AM3V matches the LOI of 5 phr ATO (30%), ensuring robust fire resistance.
Superior Smoke Suppression: AM3V reduces smoke density by up to 56% compared to ATO, critical for safety in confined spaces.
Cost Efficiency: AM3V’s significantly lower cost (1/15th of ATO) makes it a game-changer for manufacturers.

Why Replace ATO?

ATO has long been a staple in flame-retardant PVC formulations, but its high cost, environmental concerns, and regulatory scrutiny are driving the search for alternatives. AM3V addresses these challenges by offering:

Cost Savings: Drastically lower material costs without compromising performance.
Environmental Benefits: Reduced reliance on ATO aligns with global sustainability goals.
Enhanced Safety: Lower smoke density improves visibility and safety during fire incidents.

Applications

AM3V is tailored for FRLS PVC compounds used in:

Cables: Enhancing fire safety in electrical and telecommunication cables.
Construction: Providing flame-retardant properties for building materials.
Automotive and Industrial: Meeting stringent fire safety standards in diverse applications.
