DuPont shows asphalt modifier grades in Dubai

DuPont is showing two of its newly introduced Elvaloy Reactive Terpolymer asphalt modifier grades at a conference in Dubai, UAE.

The three-day sixth Middle East Bitumen/Asphalt Conference will run till May 14 at the Shangri-La Hotel.

DuPont Elvaloy RET 5160 and 5170 modifiers are the latest addition to the company’s range of asphalt modifiers that can endure the effects of weather, heavy traffic and loads, extending the drivable life of roads and highways and lowering road-repair costs.

The new grades also are shown to meet performance requirements at lower additive rates than competitive products to further lower overall cost.

Dale Outhous, vice president – ethylene copolymers, DuPont Packaging & Industrial Polymers, said: “Being able to cost-effectively build and maintain roads and highways in excellent driving condition is absolutely critical.”

The polymer chemistry used in the new grades is credited for enhancing reactivity with asphalt to achieve maximum properties with minimal modifiers. The new grades also provide the same benefits as the existing Elvaloy RET grades, including exceptional rutting resistance, cold-temperature performance, inherent fuel and water resistance, long storage stability, and efficient processing with low mixing temperatures and easy compaction, the company says.

“Harsh climate and heavy traffic conditions can cause significant damage to roads, including thermal cracking, moisture stripping, fatigue cracking, and rutting. This can substantially increase the safety risks to drivers on the roads,” says Alexandre Saba, marketing manager – Industrial and Consumer, DuPont Packaging & Industrial Polymers.

“As DuPont continues to innovate and develop new solutions for the asphalt industry, we strive to improve road safety and performance while also keeping costs low for road developers.

“We are confident that our new modifiers will be appreciated by the show’s Middle Eastern visitors as they are designed to bear the region’s high temperatures and fast-moving vehicles,: he says
