Applications:
Agricultural Fertilizer: Urea is the most common nitrogen - releasing fertilizer. It has a high nitrogen content of about 46%, making it an efficient and cost - effective source of nitrogen for plant growth. When applied to soil, urea undergoes hydrolysis, releasing ammonium ions that are readily absorbed by plant roots. It can be used for various crops, promoting lush foliage, strong stem development, and increased yield.
Industrial Uses: In the chemical industry, urea serves as a raw material for producing various compounds. It is used in the manufacture of urea - formaldehyde resins, which are widely used in adhesives, plywood, and particleboard production. Urea is also employed in synthesis the of certain pharmaceuticals, explosives, and dyes. Additionally, it plays a role in the leather and textile industries as a solvent and a softening agent.
Medical Applications: Medically, urea is used in some topical medications for its keratolytic properties. It helps to break down and remove dead skin cells, making it beneficial for treating conditions like psoriasis, eczema, and calluses. Urea is also utilized in urinary tract infection testing and as a component in some diagnostic reagents.
STORAGE:Preserve in well-closed,the storage environment of urea should be kept below 25℃. Avoid direct sunlight or high temperatures and should be stored in a cool, dry and ventilated place.
PACKAGE: Packed in 25kg bag.
