Description
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. Carbamide can be utilized in animal husbandry as fodder additive.
It is permitted to store carbamide containers and transport packages fastened by synthetic film on open areas. Warranty period of product storage – 2 years from the date of manufacturing.
