Urea Prilled 46% Nitrogen | High-Quality Prilled Urea Supplier

Urea Prilled is a nitrogen-rich, white, spherical solid known for its high solubility and consistent particle size . The prilling process involves spraying molten urea from the top of a high tower, allowing it to solidify into small, uniform droplets as it falls against an upward flow of air . This method is recognized as the most profitable and reliable for producing urea, although it presents specific environmental challenges that are often mitigated by modern manufacturing techniques.

Prilled urea is typically characterized by a mean particle diameter of around 1.64 mm, which gives it a distinct advantage for specific applications like foliar feeding and high-precision blending . Its smaller size provides a greater surface area-to-volume ratio compared to granulated urea, leading to a faster dissolution rate in water .

Chemical Structure & Properties

• Chemical Formula: CH₄N₂O or (NH₂)₂CO 

• Chemical Structure: The molecule consists of a carbonyl group (C=O) attached to two amine groups (–NH₂). This simple structure is highly stable yet readily breaks down in soil to release nitrogen.

• CAS Number: 57-13-6 

• Molecular Weight: 60.06 g/mol 

• Appearance: White, free-flowing crystalline powder or small spherical prills .

• Melting Point: 132 – 135 °C .

Specifications & Quality

H3: Technical Details

The quality of prilled urea is determined by several key parameters. Our product adheres to the highest standards, ensuring consistent performance in your applications.

• Nitrogen Content: 46% minimum by weight . This high concentration makes it one of the most efficient solid nitrogen fertilizers available.

• Biuret Content: ≤ 0.6% maximum . Biuret is a compound that can be toxic to plants if present in high concentrations. Our low biuret specification ensures safety for all agricultural applications, especially foliar spraying.

• Moisture Content:

  • Total: ≤ 0.6% .

  • Hygroscopic: ≤ 0.3% . This low moisture level minimizes caking and ensures excellent storage and handling properties.

• Particle Size: The prills typically have a mean diameter of 1.64 mm, with 90% min falling within a specific range like 0.85 – 2.80 mm or 1.0 – 2.84 mm, depending on the grade .

• Free Ammonia: 0.01 – 0.02% .

H3: Packaging Information

We offer flexible and robust packaging options to suit different logistical needs and ensure product integrity during transit and storage.

• Bulk: Available for large-scale industrial and agricultural operations.

• Big Bags: 800 kg and 1000 kg jumbo bags, suitable for bulk handling and efficient storage .

• Smaller Bags: 25 kg and 50 kg polypropylene bags for ease of handling and smaller-scale applications .

Purity, Testing & Quality Assurance

Every batch of our prilled urea undergoes rigorous testing to guarantee it meets the strictest specifications. Our Quality Assurance program includes testing for:

• Assay: Purity between 98% and 102%, often meeting USP specifications .

• Biuret Content: Analyzed via High-Performance Liquid Chromatography (HPLC) to ensure levels are below the industry maximum.

• Moisture Content: Determined by Karl Fischer titration to verify low hygroscopicity, which is a key advantage of prills over granules .

• Physical Properties: Regular testing for particle size distribution, crushing strength, and flowability ensures ease of application and blending.

Common Research Applications Include

Prilled urea serves as a vital raw material across various industries and research fields:

• Agriculture: As the primary nitrogen fertilizer for top-dressing and soil application, it promotes rapid vegetative growth . Its high solubility makes it ideal for fertigation systems and liquid fertilizer blends.

• Biochemistry: A key reagent used as a protein denaturant. It is used in studies to unfold proteins and explore their structure, function, and enzyme kinetics .

• Pharmaceuticals and Cosmetics: An active ingredient in topical creams for its moisturizing and keratolytic properties, helping to treat dry skin conditions .

• Industrial Chemistry: A precursor in the manufacture of urea-formaldehyde resins (used in adhesives and plastics), melamine, and as an additive in some adhesives and textiles .

Shipping & Availability

Our prilled urea is available for immediate shipment from our strategically located warehouses. We serve both domestic and international markets, with efficient logistics to ensure timely delivery.

• Transport: Shipped by rail, road, and sea per the applicable regulations for transporting non-hazardous, non-combustible solids .

• Inventory: We maintain substantial inventory levels to meet demand for both bulk and packaged orders.

• Lead Time: Standard lead times apply; expedited shipping options may be available upon request.

Precautions

While prilled urea is classified as a non-hazardous material for transportation , it is essential to follow standard safety procedures:

• Storage: Store in a cool, dry, well-ventilated area away from direct sunlight to prevent moisture absorption and caking .

• Handling: Wear suitable protective clothing, gloves, and eye protection to avoid contact with skin and eyes .

• Incompatibilities: Avoid contact with strong oxidizers, hypochlorites, and nitrites, as violent reactions may occur .

• First Aid: In case of eye contact, rinse immediately with plenty of water and seek medical advice
