Product application :
Dimethylformamide (DMF), as a significant chemical raw material and a high-performance solvent, is primarily utilized in industries such as polyurethane, acrylic fiber, pharmaceuticals, pesticides, dyes, and electronics. In the polyurethane industry, it serves as a washing and curing agent, mainly for the production of wet-process synthetic leather. In the pharmaceutical industry, it functions as an intermediate for drug synthesis, widely employed in the production of medications such as doxycycline, cortisone, and sulfonamides. In the acrylic fiber industry, it acts as a solvent, primarily for dry-spinning acrylic fiber production. In the pesticide industry, it is used to synthesize highly effective and low-toxicity insecticides. In the dye industry, it serves as a dye solvent. In the electronics industry, it is applied for quenching tin-plated components and cleaning circuit boards. Other applications include its use as a carrier for hazardous gases, a solvent for drug crystallization, and in adhesives, among others.
