1904 Parlin, New Jersey
The Parlin, N.J., site, acquired in the 1904 purchase of the International Smokeless Powder & Chemical Company, quickly became the center of DuPont's paint and photographic product operations. Although Parlin produced munitions during World War I, it also produced nitrocellulose-based pyroxylin brass lacquers.
In 1920 researchers at Parlin's Redpath Laboratory began developing these lacquers into films, and one attempt led fortuitously to the discovery of Duco quick-drying finish, DuPont's first major chemical invention. During World War II, Parlin switched to the production of camouflage, coatings for bombs and tanks, insect repellants, and other national defense needs. After the war, Parlin came under DuPont's Fabrics and Finishes Department. Paint manufacture was phased out, replaced by the production of Teflon® and its successors.
Development of photographic products also continued apace at Parlin. In 1920 a commercial plant for the production of 35mm film was opened under the DuPont-Pathé Film Manufacturing Corporation. In 1932 X-ray films also went into production. Both performed well. DuPont's motion picture film won an Academy Award in 1943 and Allied forces employed a wide variety of films during World War II. In the postwar years the Photo Products Department embarked on a broad research program, and Parlin developed and manufactured such products as Cyrel® flexographic printing plates and Cromalin® color proofing systems.
