For the discerning R&D scientist or product formulation specialist, understanding the precise technical specifications of a chemical additive is fundamental to achieving optimal performance. Melamine Hydrobromide (MHB), identified by CAS No. 29305-12-2, is a sophisticated flame retardant that requires a detailed look at its properties to unlock its full potential in polypropylene (PP) applications. As a dedicated manufacturer and supplier, we emphasize transparency and precision in our product data to empower your innovation.

At the core of MHB's efficacy is its chemical structure and composition. Typically, manufacturers will provide a molecular formula like C3H6N6·x(HBr) and a molecular weight around 205.99 g/mol or 207.04 g/mol, depending on the exact HBr content. More critical for practical application are its physical characteristics and performance metrics. The appearance is consistently described as a 'White Powder', which is advantageous for integration into PP compounds without significant aesthetic compromise. Crucially, its purity level, often specified as >99.0%, directly impacts its performance. Impurities can lead to reduced flame retardancy, processing issues, or undesirable side effects.

Key performance indicators for MHB include its initial decomposition temperature, typically above 300℃. This high decomposition point ensures that the flame retardant remains stable during the high-temperature processing of PP, preventing premature degradation that could compromise both material integrity and flame retardant efficacy. The particle size distribution, often specified with a D90 value (meaning 90% of particles are below a certain size, e.g., ≤10.0μm), is another vital parameter. Fine particle size generally promotes better dispersion within the PP matrix, leading to more homogeneous flame retardant properties and potentially improved mechanical performance of the final product.

The primary application driver for MHB is its ability to impart excellent flame retardancy, enabling PP to meet standards such as UL94 V2. The typical addition level required for this is remarkably low, often ranging from 1-2%. This low dosage requirement is a significant technical advantage, minimizing the impact on the PP’s inherent properties like impact strength, tensile strength, and elongation. Furthermore, MHB's ability to function effectively without the need for antimony trioxide simplifies formulations and addresses environmental concerns associated with heavy metals.

When sourcing Melamine Hydrobromide, requesting comprehensive technical data sheets (TDS) and sample materials for in-house testing is standard practice. Understanding these specifications allows R&D scientists to precisely calculate loading levels, predict processing behavior, and ensure that the final product meets all required safety and performance benchmarks. For those looking to buy Melamine Hydrobromide and partner with a reliable manufacturer and supplier, focusing on suppliers who clearly articulate and consistently deliver on these technical parameters will ensure successful and innovative product development.
