500 nm Melamine Cyanurate

2. 500 Nano Melamine Cyanurate is a high-efficiency, environmentally friendly halogen-free flame retardant prepared using advanced nano-process technology. It is based on traditional flame retardants, with particle size controlled at the nanoscale (typically around 400-500 nm) through special processes, significantly improving its specific surface area and dispersion.

5. I.6. Flame Retardant Introduction

500 nm melamine cyanurate is a high-efficiency, environmentally friendly halogen-free flame retardant prepared using advanced nano-process technology. Based on traditional flame retardants, it controls the particle size at the nanoscale (typically around 400 nm–500 nm) through a special process, significantly improving its specific surface area and dispersibility. It has excellent flame-retardant efficiency, low addition amount, good thermal stability, and good compatibility with polymer substrates (especially engineering plastics). It exerts its flame-retardant effect mainly through multiple mechanisms such as endothermic decomposition, release of inert gases to dilute combustible gases, and promotion of char formation, and is suitable for fields with high requirements for flame-retardant performance and material physical properties.
