Urea 46% Adblue grade for car

Superiority:

Urea for Adblue/SCR Agricultural/Automotive Grade

Agricultural Urea is one kind of neutral fertilizer, which can be used in long time without any harmful material in soil. Usually it can be used both for base and top dressing fertilizer in agriculture. urea contains prilled urea and granular urea .
Prilled urea : gas based and coal based ; coated and uncoated; agriculture and industry grade
Granular urea : Can be used in agriculture and producing BB fertilizer and sulfur coated urea.

• Total nitrogen (N) mass fraction: Premium grade ≥ 46%, Qualified grade ≥ 45%.
• Biuret content: Premium grade ≤ 0.9%, Qualified grade ≤ 1.5%.
• Moisture content: Premium grade ≤ 0.5%, Qualified grade ≤ 1.0%.
• Methylene diurea (calculated as HCHO) mass fraction: ≤ 0.6% .
• Granularity: For any one of the four ranges of 0.85mm - 2.80mm, 1.18mm - 3.35mm, 2.00mm - 4.75mm, 4.00mm - 8.00mm, ≥ 93% (Premium grade) or ≥ 90% (Qualified grade).

Automotive urea granules are a high-purity solid urea product specifically designed for the production of die-sel exhaust fluid (DEF), also known as AdBlue. DEF is a critical component in the Selective Catalytic Reduction (SCR) systems of die-sel vehicles, effectively reducing nitrogen oxide (NOx) emissions from die-sel engines to meet increasingly stringent global environmental regulations. Our automotive urea granules are manufactured using advanced production processes, ensuring their purity and quality meet international standards, making them an ideal raw material for producing high-quality DEF.
