For chemical professionals, including R&D scientists, formulators, and procurement specialists, a thorough understanding of chemical properties is critical for successful product development and application. 4,4'-Methylenebis(2-ethyl-6-methylaniline), commonly known as MMEA (CAS 19900-72-2), is a versatile chemical intermediate with specific properties that make it invaluable in several industries. As a dedicated manufacturer and supplier of specialty chemicals in China, we aim to provide clarity on MMEA's characteristics and applications.

MMEA is an aromatic diamine characterized by its molecular formula C19H26N2 and a molecular weight of 282.42 g/mol. Its physical appearance is typically a light yellow to off-white powder or pellet, with a melting point range of 79-86 °C. A key quality parameter is its purity, which our manufacturing process ensures is ≥98.0%. This high purity is essential for its function as a chain extender in polyurethane elastomers and as a curing agent or hardener for epoxy resins and polyurea systems. When you buy MMEA, these specifications are paramount for achieving consistent results.

The chemical properties of MMEA lend themselves to significant performance enhancements in polymer systems. In polyurethanes, it extends the polymer chains, contributing to improved tensile strength, tear resistance, and dynamic performance. For epoxy resins, MMEA acts as a cross-linking agent, imparting excellent chemical resistance, thermal stability, and mechanical toughness. Furthermore, MMEA's utility extends to being a precursor for synthesizing Polyimides and Maleimides, materials known for their exceptional heat resistance and suitability for high-performance applications like printed circuit boards. Professionals looking to purchase MMEA for these applications will find its property profile highly advantageous.

Understanding the handling and storage of MMEA is also important. It should be stored in a dry, cool, well-ventilated area, away from heat, open flames, organic chemicals, and oxidants. Its slight hygroscopicity means it should be kept in tightly sealed containers to prevent moisture absorption. As a leading chemical supplier in China, we provide detailed Material Safety Data Sheets (MSDS) and Technical Data Sheets (TDS) to guide safe handling and application. We encourage you to request MMEA pricing and technical documentation from our knowledgeable team.

In summary, MMEA (CAS 19900-72-2) is a high-performance chemical intermediate with a well-defined set of properties that are crucial for advancements in polymer science. Its efficacy as a curing agent and synthesis precursor makes it a sought-after material. By choosing to buy from a reliable Chinese manufacturer and supplier like us, you gain access to high-purity MMEA, backed by comprehensive technical support.
