PRILLED UREA

Prilled Urea TDS

• Appearance : white, slightly colored granules

• Total nitrogen : 46%

• Biuret : max. 1.2K%

• Alkalinity : max. 0.02%

• Formaldehyde : max 0.4%

• Granulomtery : 0.85 mm - 3.35 mm

CHARACTERISTICS

Prilled urea, often referred to as “urea prills,” is a type of urea that has been formed into small, spherical solid particles. Prilling is a process of spraying liquid material from the top of a tower and letting it fall down while cooling and solidifying into small spherical particles. As the urea melt falls through the tower, it cools and solidifies into small, spherical prills.

It is known for its uniform size distribution and ease of handling. However, it’s more susceptible to crushing due to its lower strength compare to granular urea. Prilled urea is often use in situations where rapid dissolution and ease of spreading are required. it has smaller and softer particles.

Use of Urea in Industries

MELAMINE POWDER

Prilled Urea is a key raw material in the production of melamine, a versatile compound used in the manufacturing of plastics, laminates, adhesives, and flame retardants. Urea undergoes condensation reactions to form melamine, which is then polymerized to produce various melamine-based product

GRANULAR UREA

Granular Urea TDS

• Appearance : white, slightly colored granules

• Total nitrogen : 46%

• Biuret : max. 1.2K%

• Alkalinity : max. 0.02%

• Formaldehyde : max 0.4%

• Granulomtery : 2mm - 5mm

CHARACTERISTICS

Granular urea, is a white, typically larger and more irregular than prilled urea, providing greater strength and reducing breakage. Hence it is a btter option for handling. It is generally free-flowing and less prone to caking, especially with surface refinement and anti-caking additives. It has high nitrogen content and has slow release. Ideal for mechanical spreading.

WOOD-BASED PANEL

Industrial Boards: Urea is also utilized in the production of industrial boards, such as particle boards and medium-density fiber-boards (MDF). These boards are widely used in construction. Urea is added to the wood fibers or particles to act as a binder, enhancing the strength and stability of the boards.

RESINS

Urea serves as a raw material in the production of plastics, resins and adhesives. Resins are widely used as adhesives in the wood and construction industries. These resins are produced by reacting urea with formaldehyde, resulting in a strong and durable adhesive. UF resins find applications in plywood, particle boards, laminates, and other wood-based products.

AUTOMOTIVE INDUSTRY

In the automotive industry, urea is commonly used in the production of automotive urea, also known as diesel exhaust fluid (DEF) or AdBlue. Automotive urea is a solution that is injected into the exhaust system of diesel vehicles to reduce nitrogen oxide (NOx) emissions, helping to meet stringent emission standards.
