The DSM team will be honored as Heroes of Chemistry at the American Chemical Society's 224th national meeting in Boston, along with chemists and chemical engineers from DuPont and Solutia Inc. Retired U.S. Air Force General Brent Scowcroft will speak at the event about what it means to be a hero in today's changing world.
"These chemical innovators have significantly contributed to the protection and security of our world with commercial technologies that detect, prevent, alleviate or remediate threats to our health and safety," said Eli Pearce, president of the American Chemical Society. "The chemical advances made by these men and women serve as testimonials to the valuable role chemists and chemical engineers play in improving our lives. It is with pride that the Society recognizes them as Heroes of Chemistry."
Personal and vehicle armor must provide maximum protection at minimal weight. Traditionally, lightweight armor was modeled on woven fabrics, but in the late 1980s, DSM learned that material made from its super-strong polyethylene fiber, called Dyneema, is better at stopping bullets when the fibers are laid in one direction and each layer of fibers is stacked in an opposite direction. The fibers and layers are bonded together with resins.
Protective gear -- including armored cockpit doors, lightweight vehicle armor panels, bullet-resistant vests and military helmets -- made with Dyneema fibers can stop, deform and dissipate energy from high-velocity bullets. The material also resists abrasion and withstands moisture, UV radiation and many chemicals. Dyneema is the world's strongest fiber and is fifteen
