a very common celebrity in the world of synthetic polymers has been useful to humans for many years now. Teflon is a fluorocarbon polymer also known by the chemical name polytetrafluoroethylene.1 The name Teflon is the registered trademark of the DuPont Company for polytetrafluoroethylene.2 However, due to polytetrafluoroethylene being commercialized under the name Teflon, it has become its commonly used name. There are countless different uses of Teflon. Due to its many amazing properties, it is
conditioner, to plastics that release that fried egg from the fry pan with perfection. These discoveries made by DuPont can arguably yield some of the most significant products made by man in the 21st century. One among the many products, polytetrafluoroethylene (PTFE, aka Teflon) is a synthetic fluoropolymer that can be used in a wide range of products. It’s extremely low coefficient of friction, and very hydrophobic and lipophobic characteristics are highly desired in its uses in non-stick coatings
T here are now a wide range of PTFE products to choose from, in the industrial gasket market place in today’s world. The product has evolved dramatically since the late 1960’s, from just virgin and commercial grade PTFE, to the present day offerings, as what is described as calendered or restructured filled PTFE sheet. PTFE has many benefits, the two most notable are, it has exceptional chemical resistance, which there are only a few chemicals that will attack the polymer, and can withstand temperatures
Polyethylene Polyethylene (PE) is one of the most commonly used polymers which can be identified into two plastic identification codes: 2 for high-density polyethylene (HDPE) and 4 for low density polyethylene (LDPE). Polyethylene is sometimes called polyethene or polythene and is produced by an addition polymerisation reaction. The chemical formula for polyethylene is –(CH2-CH2)n– for both HDPE and LDPE. The formation of the polyethylene chain is created with the monomer ethylene (CH2=CH2). The
W. L. Gore Case Analysis Although the name W. L. Gore & Associates may not seem familiar to the ear, in all actuality, its products are some of the most well-known in existence. W. L. Gore is famous for its pioneering work with the polytetrafluoroethylene polymer, which lies as the backbone for many of Gore’s products, including its most famous, Gore-Tex. Founded on January 1, 1958, by the husband and wife team of Bill and Vieve Gore in the basement of their home, W. L. Gore & Associates has expanded
Non-stick frying pans are one of the most common kitchen utensils today. Frying pan is mostly used for cooking. The non stick frying pans are made of two components, the metal body and the Non Stick layer. Actually the surface of the non stick frying pan is coated with a layer of oil or fat when the pan is in use. The layer of oil has four functions: it lubricates the surface; increases contact between the food and the pan; acts as a thermal mass to reduce the cooking time; and can be increases flavor
Jessica Hebner Professor Nedra El-Mansouri CHEM111L-011 27 November 2017 The Invention and Effective Utilization of Teflon Teflon is an important invention of the 20th century that has many purposes and is utilized in many products today. In the U.S. today, even if an individual does not know what Teflon is, it is more than likely that they have utilized it in some way. From medical equipment to household items, Teflon is an effective and readily seen substance. The discovery of Teflon grew
hip replacement operation. He developed the procedure stated above, where the head of the femur is removed and a metal implant is cemented in the bone. Along with this, a metal acetabular cup was placed in the hip socket. He originally used polytetrafluoroethylene as the material between the joints to replace the synovial fluid. The material wore down and caused problems for the patients, as it was reactive in the body. Eventually, the procedure for a hip replacement consisted of a metal femoral stem
Synthetic polymers are used by chemist to make many everyday items that we are frequently using without even realising. A common product that the use of synthetic polymers have been introduced to is various types of cosmetics and personal care items. Synthetic polymers are currently being used in cosmetics and questioned whether they are either inevitable or ineffective in their use. Synthetic polymers are already being used in cosmetics this meaning the effects of synthetic polymers must either
sciences is necessary to initiate a new technological capability and opportunity” (Berkhout, Hartmann & Trott 2010). In the Gore-Tex case, Bill and Vieve Gore, the founder of W.L. Gore Associates found fluorocarbon polymers that expanded polytetrafluoroethylene (PTFE) as an market opportunity in 1969. Second is integrated engineering cycle. Since they found the PTFE to create an opportunity to the market. Bob Gore found that the PTFE is a material that were stretching, highly flexible and would
L. Gore & Associates, Inc. is a global, privately held company headquartered in Newark, Delaware, United States. It employs approximately 8,000 associates (current employees). Gore produces proprietary technologies with versatile polymer polytetrafluoroethylene (PTFE) used in products in the health care and leisure industries. It is mainly
With the development of modern technologies, people enjoy their lives with higher level of quality. This results in the extension of average humane life time and the rapid changes of age structure of the population in the world. There are increasing demands for replacing the failed tissues on aged people. For example, if injury occurs on knees, the ability to flex the knee will be restricted due to pain. Deterioration of the knee joint would make it difficult to perform everyday activities. Even
In today’s ever changing and ever-quickening business environment, there is constant debate about what type of organizational structure is “best,” and how choice of structure impacts productivity. Companies in the same industry that receive different results may employ contrasting organizational structures. Founded in 1958, W.L. Gore and Associates trademarked Gore-Tex, a breathable, waterproof fabric (Gore, n.d., para. 1). Columbia Sportswear Company, founded in 1938 is a leading innovator in the
