Melamine, identified by CAS Number 108-78-1, is a fundamental chemical intermediate that plays a pivotal role in numerous industrial syntheses. For chemical formulators, understanding its precise properties is essential for optimizing product development and ensuring material performance. This article delves into the characteristics of Melamine and highlights its importance for sourcing from reliable manufacturers.

With the molecular formula C3H6N6 and a molecular weight of 126.12 g/mol, Melamine is characterized by its high nitrogen content (66% by mass). This intrinsic property contributes to its renowned flame-retardant capabilities. Physically, it typically appears as a white solid, with a density of approximately 1.661 g/cm³. Its solubility in water is limited, about 3 g/L at 20°C, which influences its handling and processing in various applications.

The primary utility of Melamine lies in its reaction with formaldehyde to form melamine-formaldehyde (MF) resins. These thermosetting polymers are highly valued for their exceptional hardness, scratch resistance, thermal stability, and gloss. As a formulator, incorporating these resins into products like decorative laminates, durable dinnerware, high-performance coatings, and adhesives can significantly enhance product quality and longevity.

The market demand for high-quality Melamine necessitates reliable sourcing. Manufacturers in China are significant players in the global Melamine supply chain, offering competitive prices and consistent product quality. For chemical formulators, identifying a trusted supplier is crucial. Key considerations include product purity, batch-to-batch consistency, and the ability to provide necessary technical documentation, such as Certificates of Analysis (COA).

When seeking to purchase Melamine, prospective buyers often look for specific parameters such as purity levels (often above 98.5% via acid titration) and physical form. The availability of different packaging options and adherence to international trade terms (Incoterms) are also important factors for procurement managers. Engaging with suppliers who can provide technical support and timely delivery is key to a successful procurement strategy.

In summary, Melamine (CAS 108-78-1) is a chemical workhorse with a unique set of properties that make it indispensable in many industrial sectors. Its role in creating durable and resistant materials, coupled with its fire-retardant properties, underscores its importance. Chemical formulators seeking to innovate and improve their product lines will find that a strategic partnership with a quality-focused Melamine manufacturer or supplier is a critical step towards achieving their goals.
