Product Description

We are the biggest producer and exporter of SCR/DEF Urea in China.We have been dealing with SCR/DEF Urea for 13 years.Our capacity is 500 tons/day,we export SCR Urea aroud 100,000 tons/year.
We have a production line specially for producing excellent quality SCR/DEF Urea.
Our product has very low biuret:0.8% max, and with extraordinarily low lwvel of Aldehyde.
We are producing using D-I water so our urea is without heavy metals.

Automotive grade urea is the raw material to produce AdBlue (DEF / AUS 32), which is a kind of liquid for reducing nitrogen oxide pollution in diesel vehicle exhaust.
Our product has advantages of low biuret and Aldehyde free, you can use it to produce high quality urea solution, final product can fully meet standard of ISO22241.
