Uncoated Granular Urea is also known as automotive granular urea or technical grade granular urea, a high-purity, nitrogen-rich compound commonly used in various industrial, agricultural, and commercial applications. Chemically known as carbonyl diamide, uncoated granular urea is manufactured in the form of small, spherical granules, making it highly versatile and easy to handle. With a nitrogen content of 46%, it serves as a key nitrogen source for agricultural uses, particularly as a quick-release fertilizer. Its fast solubility in water allows for efficient uptake by plants, leading to rapid greening and growth, which makes it an economical option for providing plants with nitrogen.
Aside from its primary use in agriculture, uncoated granular urea plays a critical role in industrial sectors. It is a key ingredient in the production of adhesives, and resins, and is extensively used in diesel exhaust fluids (like AdBlue) to reduce nitrogen oxide (NOx) emissions in vehicles. Additionally, its use as a high-quality nitrogen source extends to other industries that require pure nitrogen compounds. The product is free of formaldehyde and contains a biuret level of 0.90%, making it suitable for applications where a high-quality, contaminant-free nitrogen source is crucial.
Uncoated granular urea is supplied by Khorasan and Shiraz Petrochemical Companies and is classified under the HS Code 31021000. The granules have a particle size ranging from 2-4 millimeters, which ensures consistent distribution in various applications. The material’s flexibility, ease of handling, and high nitrogen content make it indispensable for both agricultural and industrial processes.
Uncoated, Automotive, or Technical Granular Urea has a variety of applications across different industries due to its high nitrogen content and solubility. Here’s a list of its primary uses:
AdBlue is a diesel exhaust fluid (DEF) that contains high-purity urea (typically around 32.5%) and deionized water (67.5%). The urea in AdBlue reacts with NOx in the exhaust gas, converting it into nitrogen and water, thereby reducing harmful emissions.
Uncoated granular urea is commonly used as a nitrogen fertilizer in agriculture. Its fast-dissolving properties make it suitable for crops that require immediate nitrogen availability for rapid growth and development.
In industries, it serves as a chemical intermediate in the production of resins, plastics, and other chemical formulations. Uncoated granular urea is essential for the manufacture of adhesives like urea-formaldehyde.
Urea is incorporated into various medicinal formulations for its therapeutic properties, including as a keratolytic agent used in dermatology to treat dry or rough skin conditions.
In laboratories, uncoated granular urea is employed for research and testing purposes. Its stable, high-purity form makes it suitable for controlled experiments and chemical reactions.
It is integral to producing urea-formaldehyde resins, which are widely used in wood products, particleboard, and laminates, as well as in various adhesives.
Uncoated urea may be used in specific food processing applications, although this is less common compared to other applications.
Urea is found in cosmetic products for its hydrating and exfoliating properties. It is used in creams, lotions, and other skincare items for moisturizing dry skin.
Granular Urea, also known as coated granular urea or agricultural granular urea, is a high-quality nitrogen fertilizer, renowned for its superior characteristics compared to prilled urea. With a nitrogen content of 46%, it stands out as the most concentrated form of solid nitrogen fertilizer available. This product is designed for optimal performance in various agricultural and horticultural applications.Granular Urea consists of larger particles with an uneven shape, which contributes to its robust physical properties. Unlike prilled urea, it is less prone to breaking and maintains its integrity during handling and application. The product is available in particle sizes ranging from 2 to 4 mm, making it suitable for use with conventional spreading equipment.The main advantage of granular urea is its high nitrogen concentration, which promotes vigorous plant growth. It can be applied directly to the soil or blended with other fertilizers such as phosphate and potash to create a comprehensive NPK (nitrogen, phosphate, and potash) mix. This versatility allows it to meet various plant nutritional needs effectively.Produced by Khorasan and Shiraz Petrochemical Companies, this agricultural granular urea is ideal for early-season grass fertilization and cereal top-dressing later in the season. It ensures precise spreading up to 24 meters, making it a reliable choice for both hand spreading and mechanical spreaders.
Granular urea is a key ingredient in the production of various other fertilizers. Its high nitrogen content makes it an essential component for creating blended or specialized fertilizers, enhancing nutrient delivery for diverse agricultural needs.
Used in the production of melamine through a reaction with formaldehyde. Melamine is a crucial component in melamine-methanal resins, which are used for durable coatings, laminates, and kitchenware, benefiting from urea’s chemical properties.
Granular urea is used in synthesizing urea-formaldehyde resin. This resin is vital in manufacturing adhesives, particleboard, and other wood products, providing strong bonding and durability in industrial applications.
Coated granular urea is employed in the reduction of nitrogen oxides (NOx) emissions from diesel engines. It is used in Selective Catalytic Reduction (SCR) systems, where it reacts with NOx to produce nitrogen and water, thus mitigating air pollution from vehicles.
It is applied to grass early in the growing season to promote healthy, early-season growth or used for top-dressing cereals later in the season. The high nitrogen content supports robust plant growth and improves crop yield, making it a versatile agricultural tool.
