Thermoplastic Elastomer
Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) that consist of materials with both thermoplastic and elastomeric properties. While most elastomers are thermosets, thermoplastics are in contrast relatively easy to use in manufacturing, for example, by injection moulding. Thermoplastic elastomers show advantages typical of both rubbery materials and plastic materials. The benefit of using thermoplastic elastomers is the ability to stretch to moderate elongations and return to its near original shape creating a longer life and better physical range than other materials. The principal difference between thermoset elastomers and thermoplastic elastomers is the type of cross-linking bond in their structures. In fact, crosslinking is a critical structural factor which imparts high elastic properties. Types There are six generic classes of commercial TPEs (de ...

University Of Akron Faculty
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic Church monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word ''universitas'' (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde' ...

Polymer Scientists And Engineers
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'', meani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colwyn Medal
Colwyn was a local government district with borough status from 1974 to 1996, being one of six districts in the county of Clwyd, north-east Wales. History The borough was created on 1 April 1974, under the Local Government Act 1972. It covered parts of four former districts from the administrative county of Denbighshire, which were all abolished at the same time:* *Abergele Urban District * Aled Rural District, except the parish of Llansantffraid Glan Conway, which went to Aberconwy *Colwyn Bay Municipal Borough * Hiraethog Rural District, except the parishes of Eglwysbach, Llanddoget, Llanrwst Rural, and Tir Ifan, which went to Aberconwy The new borough was named Colwyn, taken from the name of the area's largest town, Colwyn Bay. Under the Local Government (Wales) Act 1994, Clwyd County Council and the county's constituent districts were abolished, being replaced by principal areas, whose councils perform the functions which had previously been divided between the coun ...

Thomas Midgley Jr
Thomas Midgley Jr. (May 18, 1889 – November 2, 1944) was an American mechanical and chemical engineer. He played a major role in developing leaded gasoline (tetraethyl lead) and some of the first chlorofluorocarbons (CFCs), better known in the United States by the brand name Freon; both products were later banned from common use due to their harmful impact on human health and the environment. He was granted more than 100 patents over the course of his career. In 1944 he accidentally strangled himself to death in Worthington, Ohio. Early life Midgley was born in Beaver Falls, Pennsylvania, to a family with a history of invention. His father, Thomas Midgley Sr., was an inventor notably in the field of automobile tires. His maternal grandfather was James Emerson, who invented the "inserted tooth saw". His mother was Hattie Midgley (née Emerson). He grew up in Columbus, Ohio, and graduated from Cornell University in 1911 with a degree in mechanical engineering. On August ...

Longboat, Florida
Longboat Key is a town in Manatee and Sarasota counties along the central west coast of the U.S. state of Florida, located on and coterminous with the barrier island of the same name. Longboat Key is south of Anna Maria Island, between Sarasota Bay and the Gulf of Mexico. It is almost equally divided between Manatee and Sarasota counties. The town of Longboat Key was incorporated in 1955 and is part of the Bradenton– Sarasota–Venice Metropolitan Statistical Area.

History Early history Longboat Key was originally inhabited by Native Americans. The area of what is now Longboat Key was scouted by Juan de Añasco who was the first known European to explore the key and Hernando De Soto's scout. He spent about two months attempting to find a landing site, and he was also most likely the first European man to see and explore ...

Vulcanization
Vulcanization (British: Vulcanisation) is a range of processes for hardening rubbers. The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice. It has also grown to include the hardening of other (synthetic) rubbers via various means. Examples include silicone rubber via room temperature vulcanizing and chloroprene rubber (neoprene) using metal oxides. Vulcanization can be defined as the curing of elastomers, with the terms 'vulcanization' and 'curing' sometimes used interchangeably in this context. It works by forming cross-links between sections of polymer chain which results in increased rigidity and durability, as well as other changes in the mechanical and electrical properties of the material. Vulcanization, in common with the curing of other thermosetting polymers, is generally irreversible. The word vulcanization is derived from Vulcan, the Roman god of fire and forge.
