The
primary component of automotive urea granules is urea, with a purity
level exceeding 99.9% and free from any harmful impurities. By
dissolving the automotive urea granules in deionized water, DEF
compliant with the ISO 22241 standard can be produced. ISO 22241 is a
global standard established by the International Organization for
Standardization (ISO) for DEF, covering its chemical composition,
physical properties, storage, and usage requirements. Our automotive
urea granules ensure that the final DEF product fully complies with this
standard, meeting the demands of global markets.
