AdBlue®

CHEMIKLER EPDM & CHEMIKLER UPE are proven safe for AdBlue®

As concerns about air quality have grown, so have vehicle exhaust regulations. Since 2006, diesel trucks and buses have been equipped with selective catalytic reduction (SCR) convertors, and diesel cars followed suit a few years later.

Most SCRs reduce nitrogen oxide emissions through the use of a urea solution. For best results, this urea solution (aka AUS – aqueous urea solution 32 - or AdBlue® or DEF) must be stable from production to delivery at the station through the refilling of the vehicle’s tank – and the success of each of those steps depends in part on the availability of a high-quality hose. 

A normal rubber hose would not work. As Gérald Soulagnet, Head of the Material Development Department at Trelleborg Fluid Handling Solutions explains, “ there are strict limits to content of sulphur and it was obvious that AUS and rubber materials could interact between each other.“

Fortunately for our clients -- and our planet -- there are better alternatives. Soulagnet and his team evaluated many different options before selecting the best compound for a hose to carry a urea solution.
