Document 4: Hercules Inc.: Hercules, Inc., was a chemical and munitions manufacturing company based in Wilmington, Delaware, which was formed as the Hercules Powder Company. Hercules Powder Company was formed in 1882 by DuPont and Laflin & Rand Powder Company to finance construction of a dynamite plant on land adjacent to San Francisco Bay owned by DuPont subsidiary California Powder Works. This created the company town of Hercules, California. Hercules Inc. was a manufacturer of chemicals and munitions based in Wilmington, Delaware. The company was established in 1912 by T.W. Bacchus as the Hercules Powder Company. The Hercules Powder Company was one of the companies created from the break up of the E.I. du Pont de Nemours "powder trust" in 1911 as ruled by a U.S. Supreme Court decision. In its early years as a separate company, it continued to produce explosives and dynamite." Hercules was spun off from DuPont as a result of U.S. federal government actions in the field of antitrusts. Hercules, Inc., operated under this name until 2008, when it was merged into Ashland Inc.
Document 5: Microfiber: Microfiber (or microfibre) is synthetic fiber finer than one denier or decitex/thread. This is smaller than the diameter of a strand of silk (which is approximately one denier), which is itself about 1/5 the diameter of a human hair. The most common types of microfibers are made from polyesters, polyamides (e.g., nylon, Kevlar, Nomex, trogamide), or a conjugation of polyester, polyamide, and polypropylene. Microfiber is used to make mats, knits, and weaves for apparel, upholstery, industrial filters, and cleaning products. The shape, size, and combinations of synthetic fibers are selected for specific characteristics, including softness, toughness, absorption, water repellency, electrostatics, and filtering capabilities.
Document 6: DuPont v. Kolon Industries: DuPont v. Kolon Industries is an intellectual property lawsuit centering on the allegation that Kolon Industries (of ), a South Korea-based company, stole trade secrets concerning the production and marketing of Kevlar from DuPont, an American chemical company. Kevlar is a high strength synthetic fiber used in applications as diverse as bicycle tires and body armor. On September 14, 2011, a jury found in favour of DuPont and awarded damages of $919.9 million. A 2015 settlement reduced the damages to $275 million.
Document 7: M5 fiber: M5 fiber (polyhydroquinone-diimidazopyridine or PIPD) is a high-strength synthetic fiber first developed by the Dutch chemical firm AkzoNobel. It is produced in the United States by the Magellan Systems International, which became a division of DuPont.
Document 8: Vinylon: Vinylon, also known as Vinalon, is a synthetic fiber produced from polyvinyl alcohol, using anthracite and limestone as raw materials. Vinylon was first developed in 1939 by Ichiro Sakurada, Ri Sung Gi, and H. Kawakami. Production of this fiber was delayed for World War II. The fiber was largely ignored in Korea until Ri defected to North Korea in 1950. Trial production began in 1954 and in 1961 the massive February 8 Vinylon Complex was built in Hamhung. Vinylon's widespread usage in North Korea is often pointed to as an example of a success of the "juche" philosophy, and it is known as the "juche" fiber.
Document 9: Andrew N. Liveris: Andrew N. Liveris (born 5 May 1954) is Executive Chairman of DowDuPont and CEO and Chairman of The Dow Chemical Company, a global specialty chemical, advanced materials, agrosciences and plastics company based in Midland, Michigan with 2013 annual sales of more than $57 billion. Liveris has been a member of Dow's board of directors since February 2004, CEO since November 2004 and was elected as Chairman of the board effective 1 April 2006. Liveris became CEO in 2004 after holding the position of Chief Operating Officer (COO). He has been appointed to lead advisory groups to the White House under both the Obama administration and Trump administration.
Document 10: DuPont: E. I. du Pont de Nemours and Company, commonly referred to as DuPont, was an American conglomerate that was founded in July 1802 as a gunpowder mill by American chemist and industrialist Éleuthère Irénée du Pont.
Document 11: Kevlar: Kevlar is the registered trademark for a para-aramid synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, this high-strength material was first commercially used in the early 1970s as a replacement for steel in racing tires. Typically it is spun into ropes or fabric sheets that can be used as such or as an ingredient in composite material components.
Document 12: Polybenzimidazole fiber: Polybenzimidazole (PBI, short for poly[2,2’-("m"-phenylen)-5,5’-bisbenzimidazole]) fiber is a synthetic fiber with a very high melting point. It has exceptional thermal and chemical stability and does not readily ignite. It was first discovered by American polymer chemist Carl Shipp Marvel in the pursuit of new materials with superior stability, retention of stiffness, toughness at elevated temperature. Due to its high stability, polybenzimidazole is used to fabricate high-performance protective apparel such as firefighter’s gear, astronaut space suits, high temperature protective gloves, welders’ apparel and aircraft wall fabrics. In recent years, polybenzimidazole found its application as a membrane in fuel cells.
Document 13: Dow Chemical Company: The Dow Chemical Company, commonly referred to as Dow, was an American multinational chemical corporation headquartered in Midland, Michigan, United States, and the predecessor of the merged company DowDuPont. In 2007, it was the second-largest chemical manufacturer in the world by revenue (after BASF) and as of February 2009, the third-largest chemical company in the world by market capitalization (after BASF and DuPont). It ranked second in the world by chemical production in 2014.
Document 14: Vinyon: Vinyon is a synthetic fiber made from polyvinyl chloride. In some countries other than the United States, vinyon fibers are referred to as polyvinyl chloride fibers. It can bind non-woven fibers and fabrics. It was invented in 1939.
Document 15: Acrylic fiber: Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average molecular weight of ~100,000, about 1900 monomer units. For a fiber to be called "acrylic" in the US, the polymer must contain at least 85% acrylonitrile monomer. Typical comonomers are vinyl acetate or methyl acrylate. DuPont created the first acrylic fibers in 1941 and trademarked them under the name Orlon. It was first developed in the mid-1940s but was not produced in large quantities until the 1950s. Strong and warm, acrylic fiber is often used for sweaters and tracksuits and as linings for boots and gloves, as well as in furnishing fabrics and carpets. It is manufactured as a filament, then cut into short staple lengths similar to wool hairs, and spun into yarn.
