Dongfeng VR Group customer specific urea YKA33-10KG-PE-2

Formulated to meet the strict requirements of heavy-duty diesel engine SCR systems, the YKA33-10KG-PE-2 urea features a urea concentration of 32.5% (±0.5%)—the optimal ratio for converting nitrogen oxides (NOₓ) into harmless nitrogen and water. It undergoes a multi-stage purification process, achieving a total impurity content of ≤0.02% (including metals like copper, iron, and zinc ≤0.1mg/kg each) and a biuret content of ≤0.3%. This high purity prevents SCR system blockages (e.g., catalyst poisoning or injector clogging) and maintains NOₓ conversion efficiency at ≥95%—ensuring Dongfeng VR trucks comply with China’s National VI emission standards and reducing maintenance costs for the fleet

The urea is packaged in a food-grade high-density polyethylene (HDPE) container (thickness: 1.2mm) that offers exceptional durability and chemical resistance. The container features a triple-seal design: an inner aluminum foil seal (to prevent moisture absorption), a screw-on cap with a nitrile rubber (NBR) O-ring (to eliminate leakage during transportation), and a tamper-evident pull tab (to ensure product integrity—critical for avoiding adulteration that could damage SCR systems). The HDPE material is UV-resistant (passing 500-hour xenon lamp aging tests without brittleness) and impact-resistant (withstanding drops from 1.2m height onto concrete without cracking), making it suitable for VR’s long-distance transportation and outdoor storage conditions

Engineered to perform reliably in Dongfeng VR’s diverse operational regions (from cold northern China to hot southern areas), the YKA33-10KG-PE-2 urea maintains stability across a temperature range of -11°C to +50°C. It has a freezing point of -11°C—lower than standard urea (which freezes at -11.5°C, a negligible difference, but enhanced with a trace anti-caking agent to prevent crystal formation during thawing). When frozen, it expands by ≤2% (within the HDPE container’s expansion tolerance), avoiding container rupture. At high temperatures (up to +50°C), it resists urea decomposition (biuret formation ≤0.3% after 30 days of storage), ensuring consistent SCR performance regardless of climate—critical for VR’s cross-regional fleet operations

The YKA33-10KG-PE-2 urea fully complies with strict industry standards for automotive urea, including China’s GB 29518-2013 (Automotive Urea Solution for SCR System) and the international ISO 22241-1 standard. It undergoes batch-by-batch testing before delivery, including: urea concentration analysis (via refractometry), impurity detection (via inductively coupled plasma mass spectrometry, ICP-MS), and stability testing (freeze-thaw cycles). Additionally, the HDPE packaging meets China’s GB/T 13508-2011 (Plastic Drums for Packaging) and is recyclable (marked with PE recycling code “2”), aligning with Dongfeng VR Group’s environmental sustainability goals. This compliance guarantees the product’s safety, effectiveness, and alignment with the group’s emission reduction and sustainability commitments
