Natural Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Thailand, Malaysia, and Indonesia are three of the leading rubber producers. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into the rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale. Natural rubber is used extensively in many applications and products, either alone or in combination wit ...

Uniroyal
The company formerly known as the United States Rubber Company, now Uniroyal, is an American manufacturer of tires and other synthetic rubber-related products, as well as variety of items for military use, such as ammunition, explosives, chemical weapons and operations and maintenance activities (O&MA) at the government-owned contractor-operated facilities. It was founded in Naugatuck, Connecticut, in 1892. It was one of the original 12 stocks in the Dow Jones Industrial Average, and became Uniroyal, Inc., as part of creating a unified brand for its products and subsidiaries in 1961. The company's long-lived advertisement slogan was "''United States Tires are Good Tires''." One of Uniroyal's best known tires is the ''Tiger Paw'' introduced in the 1960s and included as original equipment for that decade's muscle cars such as the Pontiac GTO, which itself was promoted as The Tiger during its early years. Today, Uniroyal still uses the Tiger Paw brand name in its tire line. In 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polymer Scientists And Engineers
A polymer (; Greek ''wikt:poly-, poly-'', "many" + ''wikt:-mer, -mer'', "part") is a Chemical substance, substance or material consisting of very large molecules called macromolecules, composed of many Repeat unit, 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 compound (chemistry), compounds, produces unique physical property, physical properties including toughness, high rubber elasticity, elasticity, viscoelasticity, and a tendency to form glass, amorphous and crystallization of polymers, semicrystalline structures rather ...

Friction
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: *Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into ''static friction'' ("stiction") between non-moving surfaces, and ''kinetic friction'' between moving surfaces. With the exception of atomic or molecular friction, dry friction generally arises from the interaction of surface features, known as asperities (see Figure 1). *Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. *Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. *Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body. *Internal friction is the force resisting motion between the elements making up a so ...

MRPRA
The Tun Abdul Razak Research Centre, originally known as the British Rubber Producers' Research Association, carries out research into rubber and is funded by the Malaysian government. Early years: as the British Rubber Producers Research Association: 1938 to 1957 The British Rubber Producers Research Association was formed as a scientific research organization in 1938 'to understand rubber and in pursuit of this aim to mount a programme of fundamental research', since at that time the technology was almost entirely empirical.Biographical Memoirs of Fellows of the Royal Society (1999) vol 45 pp 185-194 It carried out fundamental work on rubber, which included the more general polymer science and the physics and mathematics of rheology and in addition contributed to early work on electronic computers. Prominent in the push for greater rubber research and the establishment of the association was Sir Eric Miller, who became chairman of the BRPRA. In 1939, it obtained its first prem ...

David Tabor
David Tabor (né Tabrisky), FRS (23 October 1913 – 26 November 2005) was a British physicist who was an early pioneer of tribology, the study of frictional interaction between surfaces, and well known for his influential undergraduate textbook "Gases, Liquids and Solids". Early life and education David Tabrisky was the sixth of seven children of Russian Jewish parents Charles (born "Ezekiel") Tabrisky and Rebecca (née Weinstein), who had emigrated to the United Kingdom and lived at Notting Hill Gate. His father had been a non-commissioned officer in, and armourer to, the Russian Imperial Army, and had run a business as a gunsmith and metalworker. On coming to England, he established a small metalworking business specialising in customised fittings and designs. Charles Tabrisky changed the family's surname to "Tabor" in the early 1920s. Tabor was educated at the Portobello Road Primary School, Regent Street Polytechnic Secondary School, and Imperial College London (to which he ...
