Some examples of the specialty plastics are polytetra fluoroethylene (PTFE) , thermoplastic polyurethanes (TPU), polysulphones (PSO), polyester sulphone (PES), polyarylates, polyamide imide (PAI), etc. Polyurethane is polymer composed of a chain of organic units joined by carbamate (urethane) links. Polyurethane polymers are formed by combining two bi or higher functional monomers. Urethane foam is an artificial material with several different uses. The manufacturing process can produce foams of varying densities and flexibilities. This means it can serve functions as diverse as bedding, packaging and footwear. It is important to note that urethane foam is most commonly used to refer to a material made from polyurethane. Furniture, bedding, automotive interiors, energy management, footwear and insulation utilize flexible foam technology due to its wide range of density, cushioning ability and versatility of use. Appliance (refrigeration, water heaters), construction panels, roofing boardstock, and spray applied insulation utilize rigid polyurethane foam due its superior insulating and mechanical properties to reduce energy consumption and enhance structural integrity of the finished product. The versatility of the technology and processability makes rigid polyurethane foam uniquely suited for other applications, like architectural molding, energy absorbing materials in automobiles, entry doors, and even picnic coolers.

Polyester or polyethylene terephthalate (PET) is an unreinforced, semi-crystalline thermo-plastic polyester derived from polyethylene terephthalate. Its excellent wear resistance, low coefficient of friction, high flexural modulus, and superior dimensional stability make it a versatile material for designing mechanical and electro-mechanical parts. PET is fully recyclable and can be easily reprocessed into many other products for many different applications. However, unlike paper and other cellulose products, PET does not readily decompose. However, biodegradable additives are available that enhance the biodegradation of this plastic without affecting the physical properties. Formation of a flexible polyurethane foam is an intricate process employing unique hardware, multiple ingredients and at least two simultaneous reactions. The urethane forming reaction occurs between the isocyanate and the polyol. Polyurethanes, also known as polycarbamates, belong to a larger class of compounds called polymers. Polyurethanes can be produced in four different forms including elastomers, coatings, flexible foams, and cross-linked foams. Elastomers are materials that can be stretched but will eventually return to their original shape. They are useful in applications that require strength, flexibility, abrasion resistance, and shock absorbing qualities. Thermoplastic polyurethane elastomers can be molded and shaped into different parts. This makes them useful as base materials for automobile parts, ski boots, roller skate wheels, cable jackets, and other mechanical goods. When these elastomers are spun into fibers they produce a flexible material called spandex. Spandex is used to make sock tops, bras, support hose, swimsuits, and other athletic apparel. Co-injection is the process of injecting two resins simultaneously through a single gate to form a multi-layer structure. Recently, there has been a re-emergence of interest in co-injection technology spurred on by the development of new resins, barrier systems, controls, and hardware technologies. Increasing demand of polyethylene terephthalate (PET) from food and beverage sector like in carbonated soft drinks packaging, increase demand for packaged food due to rise in consumption of frozen and processed food, rise in demand for electronics and automotive applications/industries and ecofriendly substitution are the most important driving factors in the polyethylene terephthalate market. Also, rapid urbanization, innovative packaging and high economic growth is contribution in increasing the demand for polyethylene terephthalate regardless of the geographical location. This book will be a mile stone for its readers who are new to this sector, will also find useful for professionals, entrepreneurs, those studying and researching in this important area.

Rigidity Theory and Applications by M.F. Thorpe,P.M. Duxbury Pdf
Although rigidity has been studied since the time of Lagrange (1788) and Maxwell (1864), it is only in the last twenty-five years that it has begun to find applications in the basic sciences. The modern era starts with Laman (1970), who made the subject rigorous in two dimensions, followed by the development of computer algorithms that can test over a million sites in seconds and find the rigid regions, and the associated pivots, leading to many applications. This workshop was organized to bring together leading researchers studying the underlying theory, and to explore the various areas of science where applications of these ideas are being implemented.
It is widely understood that Charles Darwin’s theory of evolution completely revolutionized the study of biology. Yet, according to David Sloan Wilson, the Darwinian revolution won’t be truly complete until it is applied more broadly—to everything associated with the words “human,” “culture,” and “policy.” In a series of engaging and insightful examples—from the breeding of hens to the timing of cataract surgeries to the organization of an automobile plant—Wilson shows how an evolutionary worldview provides a practical tool kit for understanding not only genetic evolution but also the fast-paced changes that are having an impact on our world and ourselves. What emerges is an incredibly empowering argument: If we can become wise managers of evolutionary processes, we can solve the problems of our age at all scales—from the efficacy of our groups to our well-being as individuals to our stewardship of the planet Earth.
Lift-curve Slopes Determined in Flight on a Flexible Swept-wing Jet Bomber by William S. Aiken (Jr.) Pdf
An analysis is made of the effects of Mach number and dynamic pressure on the lift-curve slope of a large flexible swept-wing jet-propelled airplane by using flight measurements of normal acceleration and angle of attack with auxiliary instrumentation as needed. The methods and procedures used to correct the flight measurements (obtained in abrupt push-pull maneuvers) and to convert the flight test data to equivalent rigid conditions for comparison with rigid-model wind-tunnel tests are described in detail. The airplane angle of zero lift and the airplane-less-tail angle of zero lift for the Mach number range of the flight tests (0.42 to 0.81) are also presented. Excellent agreement was obtained in the comparison between flight and wind-tunnel rigid lift-curve slopes and angles of zero lift.
