Description
Automotive-Grade Urea Detailed Specifications
DONGKWANG Automotive-Grade Urea Granules are engineered specifically for producing AdBlue® / Diesel Exhaust Fluid (DEF) used in SCR (Selective Catalytic Reduction) systems. Manufactured under strict quality protocols, these prilled granules feature high purity, ultra-low contaminant levels, excellent solubility, and consistent flowability, enabling stable, ISO-compliant AUS 32 production.
Designed for global emission-control standards (Euro IV, V, VI), DONGKWANG urea ensures reliable NOx reduction performance for both light-duty and heavy-duty diesel vehicles.
