Carbamide (Urea)

Carbamide(UREA) can be utilized in animal husbandry as fodder additive.
Depending on purpose, two carbamide marks are produced: A- for industry; B – for agriculture.
Carbamide is non-combustible, fire-and is explosion-proof under normal conditions. As regards to
its influence on organism, it falls into 3-rd class of hazardous substances.

APPLICATION AREA

Crystal carbamide (urea) is received from ammonia and carbon dioxide. carbamide is used in an industry as raw materials at manufacturing of pitches, glues, etc., for use in agriculture as mineral nitrogen fertilizer.
