Automotive grade urea for DEF/SCR solution
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 50,000 tons/day.
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.
