In the realm of polymer science and manufacturing, ensuring the safety and durability of plastic products is paramount. A critical component for achieving enhanced fire resistance in a wide array of plastics is Antimony Trioxide, chemically known as Diantimony Trioxide (CAS 1309-64-4). As a leading chemical manufacturer, we understand the intricate needs of B2B clients seeking high-performance additives. This article delves into the indispensable role of Antimony Trioxide as a synergist, particularly its interaction with halogenated compounds to create robust flame-retardant systems.

Antimony Trioxide is an inorganic compound that, while not a flame retardant on its own, possesses a remarkable ability to amplify the fire-retardant properties of halogenated organic compounds. When subjected to heat or flame, Antimony Trioxide undergoes a chemical reaction with halogens, typically bromine or chlorine, to form antimony halides (like SbOX). These antimony halides are volatile and interfere with the combustion process in several ways:

Firstly, they act as radical scavengers in the gas phase. Combustion is a chain reaction involving free radicals. Antimony halides effectively trap these radicals, disrupting the chain reaction and slowing down or extinguishing the flame. This is often referred to as the 'radical trap effect.'

Secondly, the formation of antimony halides and other antimony-containing species can create a protective barrier or char layer on the surface of the polymer. This char layer insulates the underlying material from heat and also prevents oxygen from reaching the combustion zone, thereby suffocating the flame. This is known as the 'air sealing effect' and 'adiabatic effect.'

The synergy between Antimony Trioxide and halogenated flame retardants allows manufacturers to achieve higher levels of flame retardancy, such as UL94 V-0 ratings, in various polymers like PVC, ABS, polyolefins, and polyesters. This is crucial for applications in electronics, construction materials, automotive components, and textiles, where fire safety is a non-negotiable requirement.
