Among the brilliant starry sky of chemical raw materials, m-phenyldimethylamine, with its unique and outstanding properties, has become an indispensable key element in many industries, leading one industrial transformation and innovation after another.
M-phenyldimethylamine is a colorless liquid at room temperature, with a molecular weight of 136.194, a density of 1.1±0.1 g/cm³, a boiling point of 247.0±0.0 °C (760 mmHg), and a melting point of 14°C. In its molecular structure, the aliphatic primary amine group and the benzene ring are ingeniously combined, endowing it with a series of remarkable properties.
The “super Engine” in the field of epoxy curing
As an epoxy resin curing agent, m-phenyldimethylamine is a leader in the industry. Because it contains aliphatic primary amine groups, it can rapidly exert curing effects at room temperature, significantly shortening the production cycle and enhancing production efficiency. The cured product not only has excellent heat resistance and can remain stable in high-temperature environments, which is superior to common aliphatic polyamines; It also has outstanding chemical resistance. Whether it is organic solvents such as toluene or corrosive media such as 10% wt sulfuric acid, it is difficult to cause damage to it. This feature has enabled it to shine brightly in the fields of battery sealing adhesives and terminal post adhesives. With the advantages of low viscosity, easy flow and excellent penetration, it ensures that the adhesive can be perfectly sealed, resisting the erosion of acid gas and acid liquid, and withstanding external force impacts, thus safeguarding the safe and stable operation of batteries. Meanwhile, in the application of anti-corrosion coatings for bridge repair, pipeline coating, ship containers, floors, etc., m-phenylenediamine, in combination with epoxy resin, can demonstrate excellent adhesion even in humid environments, effectively resisting harsh conditions and extending the service life of facilities.
“Innovation Booster” for diversified industries
In the production of polyurethane resins and coatings, m-phenyldimethylamine serves as a key raw material and participates in the construction of high-performance molecular structures. It can significantly enhance the flexibility, wear resistance and impact resistance of polyurethane materials, endowing coatings with superior weather resistance and gloss. It is widely used in surface decoration and protection in furniture, automobiles, construction and other fields. In the field of rubber additives, its addition can optimize the vulcanization process of rubber, enhance the strength, elasticity and aging resistance of rubber products, and comprehensively improve the quality of rubber products from tires to rubber seals. In addition, m-phenyldimethylamine is also an important monomer for the synthesis of high-performance nylon materials such as polyadipylm-phenyldimethylamine (MXD6). MXD6, with its unique structure endowed by m-phenyldimethylamine, features high barrier properties (oxygen permeability is only 1/10 of PA6), high strength and rigidity (tensile strength up to 280MPa, flexural modulus up to 24GPa), good heat resistance (heat distortion temperature up to 73.8℃, 1.8MPa), and low water absorption rate. It has demonstrated tremendous application potential in cutting-edge fields such as lightweight materials for robots, components for new energy vehicles, and high-end food packaging, and has become a core force driving industrial upgrading. Not only that, in many industries such as photosensitive plastics, pesticides, fiber finishing agents, rust inhibitors, chelating agents, lubricants, and paper processing, m-phenyldimethylamine, with its unique properties, provides a continuous driving force for product innovation and performance optimization.
From the production source to the final application, m-phenyldimethylamine strictly adheres to quality control. The production process adopts advanced technology, starting from a mixture of m-xylene and p-xylene, and then undergoing oxidation reactions with air and ammonia to generate m-xylene and p-phenyldimethylnitrile. Subsequently, it undergoes a series of precise steps such as water washing, drying, and catalytic hydrogenation, ultimately obtaining high-purity products. Each batch of products undergoes strict testing to ensure a purity of ≥ 99.0%, with all indicators stable and reliable, providing customers with a reassuring choice. The product is packaged in 200-kilogram plastic drums for convenient transportation and storage. It should be stored in a cool and well-ventilated place, strictly adhering to the storage and transportation regulations for flammable and toxic substances to ensure that the product quality is not affected.
M-phenyldimethylamine, with its outstanding performance as the foundation and diverse applications as the wings, is helping various industries break through technical bottlenecks and embark on a new journey of higher quality and more innovative development. Join hands with m-phenyldimethylamine and embrace the boundless future of the chemical industry together!
