• DEF Blending with Other Additives - Blending diesel exhaust fluid (DEF) with other additives is an evolving strategy within the Global DEF Market aimed at enhancing performance and addressing specific operational needs across various industries. DEF, typically a solution of urea in purified water, is integral to Selective Catalytic Reduction (SCR) systems used in diesel engines to reduce nitrogen oxide (NOx) emissions. Blending DEF with additives can offer additional benefits such as improved freezing point depressants, corrosion inhibitors, and stabilizers, which optimize performance in diverse environmental conditions.

  One common additive blended with DEF is corrosion inhibitors, which help protect SCR system components from corrosion caused by the urea solution. This is particularly crucial in environments with varying temperatures and humidity levels. Additives that lower the freezing point of DEF are essential for applications in colder climates, ensuring the fluid remains effective even in sub-zero temperatures. Such enhancements in DEF formulations enable reliable operation and compliance with emissions regulations across different geographic regions and operational conditions.

  The blending of DEF with additives is also explored for enhancing the fluid's stability and longevity during storage and use. Stabilizers can prevent urea decomposition and degradation, maintaining the integrity and effectiveness of DEF over extended periods.
