Description
Automotive Grade Urea
Our product has the advantages of being low biuret and aldehyde-free, you can use it to produce high-quality urea solution, and the final product can fully meet the standard of ISO22241.
Description of low biuret urea 99% high purity SCR UREA with SGS testing What is SCR?-—SCR (Selective Catalytic Reduction) transforms the harmful nitrogen oxides (NOx) in the exhaust of diesel vehicles into harmless nitrogen gas and water vapor. The SCR solution is metered into the exhaust system in front of a catalyst. The urea hydrolyses to ammonia which then reacts with the NOx in the exhaust gas.
What is DEF?—-DEF is an aqueous urea solution used in SCR systems on diesel vehicles. SCR Urea complies with ISO 22241-1 and DIN 70070 standards
why ourSCR urea can be making DEF?—-The raw material of our urea is pure natural gas, so the urea has low Biuret, low Aldehydes, and low heavy metal materials; We have the most advanced production equipment and testing equipment.

For small samples quantity <1 kilogram, inside we use double resealable zip bags, and outside with aluminum Foil Bags.
For larger quantities>25 kilograms, normally we pack them in drums(normally 25 kg per) with two strong PET bags.
We do supply smaller packages like 10 grams/50 grams per bag as your requirement. Please contact us for more details if you have any questions!
