4,4`- Methylenedianiline
4,4`-Methylenedianiline (MDA) is a key aromatic amine used primarily as a monomer in polyurethane and diisocyanate production. This chemical intermediate delivers high temperature resistance, making it suitable for applications where thermal stability is critical. Its molecular structure enables strong insulation properties, high mechanical strength, and chemical stability, which are essential in demanding industrial environments.
MDA is commonly supplied as a crystalline solid or liquid, depending on purity and intended use. In polyurethane systems, it acts as a chain extender, while in epoxy formulations, it serves as a curing agent. Typical industry grades for MDA include polymerization-grade and technical-grade, with purity levels often exceeding 99% for high-performance applications. The material is also a precursor for specialty resins such as polyimide (PI) and polyester imide (PEI), which are used in aerospace and electrical insulation.
Industrial buyers source MDA for manufacturing heat-resistant cables, transformer insulation, motor liners, and high-grade insulating paints. It is also used in the production of bihorse resin and other advanced composites. Buyers should confirm packaging options, as MDA is often shipped in sealed drums or bags to prevent moisture absorption. Trade terms, including MOQ and lead times, should be verified directly with Henan Profession Chemicals Co.,Ltd., as these can vary based on order volume and destination.

Sourcing 4,4`- Methylenedianiline from Henan Profession Chemicals Co.,Ltd. - China Import Guide
Before ordering MDA from Henan Profession Chemicals Co.,Ltd., verify the chemical’s purity, molecular weight, and intended application compatibility. Request a Certificate of Analysis (COA) to confirm these specifications meet your production requirements. Ensure the supplier can provide lot-specific data, as batch variations may occur.
Confirm logistics details, including Incoterms (e.g., FOB or CIF), lead times, and port of loading in China. MDA is often shipped as a hazardous material, so check if the supplier handles export documentation, such as MSDS and IMDG compliance. Payment terms, such as TT or LC, should also be clarified upfront to avoid delays.
Conduct quality checks upon receipt, including visual inspection for contamination and laboratory testing for purity and moisture content. For aerospace or electrical applications, additional tests like thermal stability (TGA) or dielectric strength may be necessary. Request the supplier’s recommended testing protocols and retain samples for future reference.
