Tyvek
Tyvek () is a brand of synthetic flashspun high-density polyethylene fibers. The name "Tyvek" is a registered trademark of the American multinational chemical company DuPont, which discovered and commercialized Tyvek in the late 1950s and early 1960s. Tyvek's properties - such as being difficult to tear but easily cut, and waterproof against liquids whilst allowing water vapor to penetrate - have led to it being used in a variety of applications. Tyvek is often used as housewrap, a synthetic material used to protect buildings during construction, or as personal protective equipment (PPE). History Tyvek is a nonwoven product consisting of spun bond olefin fiber. It was first discovered in 1955 by a researcher for the DuPont textile company working in an experimental lab, who noticed a type of white fluff coming out of a pipe. That fluff was a form of polyethylene, which DuPont requested a patent for within a year of the discovery. After technologies improved during the next few ...

Polymer Banknotes
Polymer banknotes are banknotes made from a synthetic polymer such as biaxially oriented polypropylene (BOPP). Such notes incorporate many security features not available in paper banknotes, including the use of metameric inks. Polymer banknotes last significantly longer than paper notes, causing a decrease in environmental impact and a reduced cost of production and replacement. Modern polymer banknotes were first developed by the Reserve Bank of Australia (RBA), Commonwealth Scientific and Industrial Research Organisation (CSIRO) and The University of Melbourne. They were first issued as currency in Australia during 1988 (coinciding with Australia's bicentennial year); by 1996, the Australian dollar was switched completely to polymer banknotes. Romania was the first country in Europe to issue a plastic note in 1999 and became the third country after Australia and New Zealand to fully convert to polymer by 2003. Other currencies that have been switched completely to polymer b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bradbury Wilkinson And Company
Bradbury Wilkinson & Co were an English engraver and printer of banknotes, postage stamps and share certificates. History The original company was established in the 1850s by Henry Bradbury and begun printing banknotes in 1856. Bradbury then died in 1860. In 1873–74, the firm built an imposing six-storey workshop, for engraving printing plates, in Holborn, London at 25 and 27 Farringdon Road, which is now a Grade II-listed building. The company printed the first series of the Imperial Bank of Persia banknotes that were issued in 1890. In 1903, the company was acquired by the American Bank Note Company. In 1917, it moved to New Malden in Surrey still operating as Bradbury-Wilkinson as a wholly owned subsidiary of ABNC. In 1983, Bradbury Wilkinson created a form of polymer banknote using Du Pont's Tyvek material; this was marketed as Bradvek and used to print 1-pound banknotes for the Isle of Man. In 1986 the company was acquired by De La Rue. The site is now occupied by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polymer
A polymer (; Greek '' poly-'', "many" + ''-mer'', "part") is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compounds, produces unique physical properties including toughness, high elasticity, viscoelasticity, and a tendency to form amorphous and semicrystalline structures rather than crystals. The term "polymer" derives from the Greek word πολύς (''polus'', meaning "many, much") and μέρος (''meros'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DuPont
DuPont de Nemours, Inc., commonly shortened to DuPont, is an American multinational chemical company first formed in 1802 by French-American chemist and industrialist Éleuthère Irénée du Pont de Nemours. The company played a major role in the development of Delaware and first arose as a major supplier of gunpowder. DuPont developed many polymers such as Vespel, neoprene, nylon, Corian, Teflon, Mylar, Kapton, Kevlar, Zemdrain, M5 fiber, Nomex, Tyvek, Sorona, Corfam and Lycra in the 20th century, and its scientists developed many chemicals, most notably Freon (chlorofluorocarbons), for the refrigerant industry. It also developed synthetic pigments and paints including ChromaFlair. In 2015, DuPont and the Dow Chemical Company agreed to a reorganization plan in which the two companies would merge and split into three. As a merged entity, DuPont simultaneously acquired Dow and renamed itself to DowDuPont on August 31, 2017, and after 18 months spin off the merged en ...

American Banknote Company
ABCorp is an American corporation providing contract manufacturing and related services to the authentication, payment and secure access business sectors. Its history dates back to 1795 as a secure engraver and printer, and assisting the newly formed First Bank of the United States to design and produce more counterfeit resistant currency. The company has facilities in the United States, Canada, Australia, and New Zealand. The American Bank Note Company is a wholly owned subsidiary of ABCorp. Origins Robert Scot, the first official engraver of the young U.S. Mint, began the company that would eventually grow into a high security engraving and printing firm, the American Bank Note Company. Founded in 1795 as Murray, Draper, Fairman & Company after Scot's three partners, the company prospered as United States population expanded and financial institutions proliferated. Its products included stock and bond certificates, paper currency for the nation's thousands of state-chart ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
