For B2B professionals in the chemical and materials sector, understanding the precise specifications of a raw material is fundamental to successful formulation and production. 4,4'-Methylenebis(2,6-diethylaniline), known as MDEA, is a critical component in various high-performance applications, from polyurethanes to epoxies. As a leading manufacturer and supplier in China, we are committed to transparency and providing detailed information about our MDEA products to empower your procurement decisions.

One of the most crucial specifications for MDEA is its purity. Our standard product typically offers a purity of ≥99.0% (often determined by HPLC). This high level of purity is essential for predictable reactivity and consistent performance in your end products. Lower purity grades can lead to unpredictable curing times, altered mechanical properties, and potential defects in the final material. For applications demanding the utmost precision, such as in advanced composites or specialized coatings, sourcing high-purity MDEA from a reputable manufacturer is non-negotiable.

The appearance of MDEA is another important physical characteristic. It is commonly described as a White Powder or Granules. This visual cue can be an initial indicator of quality. Variations in color or form might suggest contamination or improper storage, so always expect a consistent white appearance from a quality product. The melting point is also a key physical parameter, typically ranging from 87-89°C. This value is crucial for formulators who need to understand the material's behavior under processing temperatures.

Handling and storage are equally vital aspects when considering MDEA. While it is a stable compound, it is advisable to store it in a dry, cool, and well-ventilated area, away from direct sunlight and incompatible materials. Like many aromatic amines, it can be sensitive to moisture and air over prolonged periods. Proper sealing of containers after use is recommended to maintain its quality and extend its shelf life. As a responsible supplier, we provide comprehensive Material Safety Data Sheets (MSDS) that detail safe handling procedures, protective measures, and disposal guidelines. We encourage all our clients to review these documents thoroughly before use.

When you are looking to buy MDEA, consider the value of working with a direct manufacturer that can guarantee these specifications. Our aim is to simplify your procurement process by providing clear, accurate data and reliable products.
