In 1802, DuPont was primarily an explosives company. One hundred years ago, its focus turned to chemicals, materials and energy. Today, DuPont delivers science-based solutions that make real differences in people's lives and addresses global megatrends such as food, energy and protection. DuPont's ability to adapt to change and a foundation of unending scientific inquiry have enabled DuPont to become one of the world's most innovative companies. But, in the face of constant change, innovation and discovery, its core values have remained constant: commitment to safety and health; environmental stewardship; high ethical behaviour; and respect for people. DuPont is a Fortune 500 company. Among its brands: the DuPont Oval and DuPont (The "DuPont Brand Trademarks"); Pioneer® brand seeds, Teflon® fluoropolymers, films, fabric protectors, fibres, and dispersions; Corian® solid surfaces; Kevlar® high strength material, and Tyvek® protective material, among many others.
