High-end applications of DMF

As a traditional universal solvent, DMF has been widely used in many industries. Because it is miscible with most organic solvents, it can be used as a better aprotic polar solvent. In the synthesis of polyurethane: DMF can dissolve the polyurethane molecular chain, promote the extension of the molecular chain and increase the molecular weight, thereby improving the physical properties and service life of polyurethane; in the production of some high-efficiency and low-toxic pesticides, DMF is used as a melting medium to fuse various raw materials reaction; in the pharmaceutical industry, DMF is used as a solvent and stabilizer for pharmaceutical preparations, which can help dissolve pharmaceutical ingredients and maintain the stability and consistency of preparations; in the electronic field, DMF is used to dissolve and process electronic materials, such as Photovoltaic materials, copper clad laminates, etc.

In high-end application requirements, DMF is an important solvent for preparing high-end polyimide resin (PIF), and its index requirements are more stringent. Polyimide films processed from polyimide resin are particularly suitable for use as flexible printed circuit board substrates and various high-temperature-resistant electrical and motor insulation materials due to their excellent insulation and mechanical properties. They are also known as " Gold Film". As the flexible copper clad laminate (FCCL) market maintains high growth, the high-end electronic grade polyimide film market will be in a period of rapid expansion, and DMF will also occupy an important position in its development. Also in high-end coatings and special ink formulations, DMF serves as an indispensable co-solvent, which can adjust the fluidity, viscosity and drying speed of coatings and inks. With the continuous innovation of coatings and ink materials and processes, market demand increases, and the application fields will also become wider.
