    AI Overview
    Technical grade urea (AUS32) is a high-purity urea used to produce AdBlue® (Diesel Exhaust Fluid), consisting of 32.5% urea and 67.5% demineralized water. It complies with ISO 22241 standards to ensure zero contamination (free of metals/aldehydes), protecting selective catalytic reduction (SCR) systems. It is crucial for reducing NOx emissions in diesel engines. 
    Key Characteristics and Technical Specifications: 
    • Composition: 32.5% urea, 67.5% demineralized water.
    • Purity Requirements: Must be uncoated, low-biuret, and free from heavy metals/aldehydes to prevent SCR damage.
    • Standardization: Adheres to ISO 22241.
    • Application: Used in Euro 4, 5, and 6 diesel engines with Selective Catalytic Reduction (SCR) technology.
    • Storage Requirements: Must be stored between -11°C and 30°C to avoid degradation; temperatures above 35°C should be avoided. 
    Benefits of High-Quality Technical Urea: 
    • Emission Control: Reduces harmful nitrogen oxides (NOx) in diesel exhaust by up to 90%.
    • System Protection: Prevents corrosion of urea pumps, sensors, and catalytic converters. 
    Important Distinctions:
    Do not confuse technical grade urea (AUS32) with agricultural urea. Agriculture grade contains high levels of anti-caking agents and heavy metals, which will destroy the SCR system and void vehicle warranties.
