Adblue consists of 32.5% high purity urea and 67.5% deionized water.

Colorless, translucent, non toxic, corrosive, pH value is 10; It can dissolve continuously at high temperature and crystallize above minus 11.5 ℃.

NH ₃ will corrode and irritate human skin tissue in contact. If exposed to ammonia for a long time, skin pigment deposition or skin ulcer may occur. (in case of such a situation, seek medical treatment immediately to avoid more serious consequences).

The main purpose of adding AdBlue to diesel vehicles is to reduce nitrogen oxides (NOx) in the exhaust gas discharged by diesel engines. Vehicle urea is evenly injected into the vehicle exhaust through the selective exhaust catalytic reduction system (SCR) of diesel vehicles, and the urea is quickly decomposed into ammonia at high temperature (NH ₃) and conduct catalytic reduction reaction with NOx at the same time, and finally generate harmless N2 and H ₃ o emissions.
