Testimonials
“Our team at the NASCAR R&D Center went to great lengths to study ways in which energy can be absorbed during impacts on the race track and the IMPAXX energy foam developed by Dow Automotive is what we found worked the best. The IMPAXX foam has performed extremely well in protecting our drivers and has proven to be a highly effective safety feature that NASCAR plan to incorporate further in our sport.”
“The car, equipped with Impaxx, hit the wall at 200 mph and rolled over eight times. McDowell walked away, got into a backup car and qualified for the Samsung 500 race”
