New DuPont™ Elvaloy® RET Asphalt Modifiers Can Help Achieve Longer-Lasting Road Performance

Expanding Our Horizons with Elvaloy® 5160 and 5170 (Asphalt Modification)

Advanced Material Solution Based on Unique Polymer Chemistry

WILMINGTON, Del., May 11, 2015 – DuPont Packaging & Industrial Polymers (DuPont) introduced two new Elvaloy® RET asphalt modifier grades to fight the effects of weather, heavy traffic and loads, which can extend the drivable life of roads and highways and help lower road-repair costs. The new grades also are shown to achieve performance requirements at lower additive rates than competitive products to further lower overall cost.

DuPont™ Elvaloy® RET 5160 and 5170 modifiers are the latest addition to DuPont’s growing portfolio of asphalt modifiers.

“Being able to cost-effectively build and maintain roads and highways in excellent driving condition is absolutely critical, and we are committed to using our materials science capabilities to optimize our existing portfolio,” said Dale Outhous, vice president, Ethylene Copolymers, DuPont Packaging & Industrial Polymers.

The unique 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.

“Harsh climate and heavy traffic conditions can cause significant damage to roads, including thermal cracking, moisture stripping, fatigue cracking and rutting, substantially increasing the safety risks to drivers on the roads,” said 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.” Additional Elvaloy® RET grades are expected in 2016.

Elvaloy® RET modifiers are designed to outlast a variety of weather conditions from the Arctic to the desert – giving manufacturers confidence in their roads and their performance throughout the coldest and the hottest weather. With nearly 25 years of paving experience, DuPont estimates that more than 95,000 miles of roads around the world are paved with Elvaloy® RET.
