Urea Automotive Grade (DEF / AdBlue)

High-Purity Urea for Diesel Emission Control Systems

Urea Automotive Grade is a high-purity urea specifically produced for use in Diesel Exhaust Fluid (DEF / AdBlue) solutions used in modern diesel engines. It plays a critical role in reducing harmful emissions in vehicles equipped with Selective Catalytic Reduction (SCR) systems.

Chemienral supplies premium automotive-grade urea designed to meet the strict purity requirements necessary for DEF production, ensuring reliable performance in emission control applications.

Urea Automotive Grade is a refined form of urea manufactured with extremely low impurity levels to comply with the quality requirements of DEF production.

When dissolved in deionized water (typically 32.5% urea solution), it forms Diesel Exhaust Fluid, which is injected into the exhaust stream of diesel vehicles. Inside the SCR catalyst, the solution helps convert harmful nitrogen oxide emissions into harmless nitrogen and water vapor.

This process helps diesel vehicles comply with global emission standards.

Key Features

  • Ultra High Purity: Produced to meet strict automotive-grade standards

  • Low Biuret Content: Prevents catalyst damage in SCR systems

  • Consistent Quality: Reliable performance in DEF production

  • High Solubility: Easily dissolves to produce stable DEF solution

  • Low Dust Granules: Suitable for industrial processing

  • Global Compliance: Suitable for DEF manufacturing meeting international standards

Main Application

Diesel Exhaust Fluid (DEF / AdBlue) Production

Automotive-grade urea is the key raw material used to produce Diesel Exhaust Fluid, a solution widely used in:

  • Passenger diesel vehicles

  • Trucks and heavy-duty vehicles

  • Agricultural machinery

  • Construction equipment

  • Marine diesel engines

In SCR systems, DEF converts harmful nitrogen oxides (NOx) into environmentally safe compounds.

Industry Importance

With increasingly strict emission regulations worldwide, DEF has become essential for modern diesel engines meeting standards such as:

  • Euro 6

  • EPA Tier 4

Automotive-grade urea ensures reliable DEF production that protects the SCR catalyst and maintains emission compliance.
