Urea for Automotive/SCR/Fertilizer/Industry/Technical Use with SGS Testing Report
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.

Uses
Urea is a high concentration of nitrogen fertilizer, is a neutral organic fertilizer, also can be used in the production of a variety of compound fertilizer. In industry, for steel, stainless steel chemical polishing has whitening effect, used as a corrosion inhibitor in the metal pickling, also used in the preparation of the palladium activation fluid..
Packing and Transport
50kg ,500kg,1000kg PP bag or pallet available ,Stored in cool, dry and draughty storehouse. Kept away form fire, heat source, moisture. Avoid packing damage. when necessary should be placing the waterproof canvas.
