Biurea is primarily used as a blowing agent in the production of foamed plastics, where it helps create lightweight and porous materials by releasing gas during the thermal decomposition process. It is also employed in the synthesis of certain polymers and resins, contributing to their structural integrity and stability. In the agricultural sector, biurea serves as an intermediate in the production of herbicides and other crop protection chemicals. Additionally, it finds application in the manufacture of adhesives and coatings, enhancing their performance and durability. Its role in chemical synthesis and material science makes it a valuable component in various industrial processes.
