Topblue AdBlue reduces Nitrogen Oxide (NOx) emissions. Nitrogen oxide is a harmful gas that can damage the human respiratory system, reducing lung function, increasing allergen exposure and the risk of respiratory illnesses. It promotes the formation of fine particulate pollution and ground ozone – harmful to both health and vegetation.

It’s for these reasons that governments set limits on vehicular NOx emissions and promote the use of AdBlue. This improves air quality and reduces the danger of diesel pollution-related illness and death.

The term AdBlue is a worldwide trademark of the German Association of the Automotive Industry (VDA) relating to DEF produced in accordance with the ISO 22241 specifications.

TopBlue AdBlue is a recognised international AdBlue manufacturer with years of experience and expertise. As part of the Sinopec group and a direct subsidiary of Sichuan Meigeng Chemical, and is one of the largest manufacturers of Automotive Grade Urea (AGU), the main component in the manufacture of AdBlue. Urea contains ammonia; the active ingredient in AdBlue that reacts with NOx and neutralises it before it enters the atmosphere.

Our AdBlue is made of a colourless mixture of high-purity urea (32.5%) and deionised water (67.5%), as set out in the ISO 22241 standard.
