In the world of flame retardants, antimony trioxide (Sb₂O₃) plays a unique and irreplaceable role: it is not the traditional "main flame retardant", but an efficient "chemical multiplier" or "reaction catalyst". The effectiveness of its flame retardant depends strictly on its coexistence with halogens (chlorine or bromine).

In the field of flame-retardant materials engineering, the application of antimony trioxide (Sb₂O₃) has always been accompanied by significant performance trade-offs. It serves as both a "multiplier" for enhancing halogen-based flame retardancy and a "double-edged sword" that may compromise the overall performance of materials.

Melamine Cyanurate Granular (MCA) is a specialized form — the granular grade — of melamine cyanurate, widely used as a halogen‑free flame retardant with excellent thermal stability and smoke suppression. In this comprehensive guide, we will explore the properties, mechanisms, applications, benefits, selection criteria, and industry relevance of this material, with detailed FAQs and references from industry sources.

In the practice of using antimony trioxide (Sb₂O₃) for plastic flame retardancy, "uneven dispersion" is the primary process challenge that leads to fluctuations in flame retardant efficiency, deterioration of material mechanical properties, and appearance defects in products.

In the field of flame retardant science, antimony trioxide (Sb ₂ O3) holds a unique and classic position. It is not a strong flame retardant in itself, but when coexisting with halogen compounds, it can exhibit astonishing synergistic effects, increasing the overall flame retardant efficiency several times.

In the selection of halogen-free flame retardants, aluminum hypophosphite (AHP) is not a "master key", and its excellent performance is highly dependent on the "chemical dialogue" with the polymer matrix.
