Plastics Plastics The chemical compound 1,2-dichloroethane, commonly known by its old name of ethylene dichloride (EDC), is a chlorinated hydrocarbon, mainly used to produce vinyl chloride monomer (VCM, chloroethene), the major precursor for PVC production. 1,2-Dichloroethane is also used generally as an intermediate for other organic chemical compounds, and as a solvent. ...more on Wikipedia about "1,2-Dichloroethane"
Accumulator Head Machinery is used for the extrusion blow molding of large industrial hollow parts. Examples of parts produced on this machinery include drums, trash cans, automotive panels, playground equipment, and large containers, such as Jerry Cans, for liquid storage. Most parts produced on accumulator head machinery are single layer; however, specialized machinery is capable of producing parts with up to seven unique layers of plastic - these machines are used primarily to manufacture automotive gasoline tanks with barrier layers. ...more on Wikipedia about "Accumulator head machinery"
Acrylonitrile butadiene styrene, or ABS, ( chemical formula ) is a common thermoplastic used to make light, rigid, molded products such as pipes, golf club heads (used for its good shock absorbance), automotive body parts, enclosures, protective head gear, and toys including Lego bricks. It is a copolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The proportions can vary from 15% to 35% acrylonitrile, 5% to 30% butadiene and 40% to 60% styrene. The result is a long chain of polybutadiene criss-crossed with shorter chains of poly(styrene-co-acrylonitrile). The nitrile groups from neighbouring chains, being polar, attract each other and bind the chains together, making ABS stronger than pure polystyrene. The styrene gives the plastic a shiny, impervious surface. The butadiene, a rubbery substance, provides resilience even at low temperatures. ABS can be used between -25 °C and +60 °C. ...more on Wikipedia about "Acrylonitrile butadiene styrene"
Bakelite is a brand named material based on the thermosetting phenol formaldehyde resin polyoxybenzylmethylenglycolanhydride, developed in 1907- 1909 by Dr. Leo Baekeland. Formed by the reaction under heat and pressure of phenol and formaldehyde, generally with a wood flour filler, it was used for its nonconductive and heat-resistant properties in radio and telephone casings and electrical insulators. ...more on Wikipedia about "Bakelite"
Blow molding is a manufacturing process by which hollow plastic parts are formed. In general, there are three main types of blow molding; Extrusion Blow Molding, Injection Blow Molding, and Stretch Blow Molding. ...more on Wikipedia about "Blow molding"
In polymer chemistry, branching occurs by the replacement of a substituent, e.g, a hydrogen atom, on a monomer subunit, by another covalently bonded chain of that polymer; or, in the case of a graft copolymer, by a chain of another type. In crosslinking rubber by vulcanization, short sulfur branches link polyisoprene chains (or a synthetic variant) into a multipy-branched thermosetting elastomer. Rubber can also be so completely vulcanized that it becomes a rigid solid, so hard it can be used as the bit in a smoking pipe. Polycarbonate chains can be crosslinked to form the hardest, most impact-resistant thermosetting plastic, used in safety glasses. ** ...more on Wikipedia about "Branching (chemistry)"
Celluloid is the name of a class of compounds created from nitrocellulose and camphor, plus dyes and other agents, generally regarded to be the first thermoplastic. Easily molded and shaped, there are suggestions that celluloid was first made as an ivory replacement. Celluloid is highly flammable and also easily decomposes, and is no longer widely used. ...more on Wikipedia about "Celluloid"

Duroplast is a composite material, a close relative of formica and bakelite. It is a resin plastic reinforced with fibres (either cotton or wool) making it a fibre reinforced plastic similar to glass-reinforced plastic, but because it can be made in a press simmilar to shaping steel it is more suitable for volume car production. ...more on Wikipedia about "Duroplast"
The term elastomer is often used interchangeably with the term rubber, and is preferred when referring to vulcanisates. They are amorphous polymers existing above their glass transition temperature, so that considerable segmental motion is possible. At ambient temperatures rubbers are thus relatively soft ( E~3MPa) and deformable. Their primary uses are for seals, adhesives and molded flexible parts. ...more on Wikipedia about "Elastomer"
Engineering plastics are plastics that regain their original shape after deformation. If an engineering plastic reaches a critical amount of deformation, it may be unable to regain its original shape. ...more on Wikipedia about "Engineering plastic"

Heat shrink tubing (or commonly "heat shrink") is a thin polyolefin tube which shrinks in diameter when heated. It is sometimes lined with adhesive to prevent it from sliding off. It finds use in insulating electrical wire repairs, bundling wires together, and protecting wires or small parts from minor abrasion. ...more on Wikipedia about "Heat shrink tubing"
A hot runner is an injection mold component containing a series of channels that distributes molten plastic within a mold. Unlike an ordinary cold runners, the hot runners are heated, so the plastic melt in the hot runners never freeze. ...more on Wikipedia about "Hot runner"
Injection moulding ( United States Injection Molding) is a manufacturing technique for making parts from plastic material. Molten plastic is injected at high pressure into a mould, which is the inverse of the desired shape. The mould is made by a mouldmaker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection moulding is very widely used for manufacturing a variety of parts, from the smallest component to entire body panels of cars. It is the most common method of production, with some commonly made items including bottle caps and outdoor furniture. ...more on Wikipedia about "Injection moulding"

Neoprene is the DuPont Chemical trade name for a family of synthetic rubbers based on polychloroprene. It is used in a wide variety of environments, such as in wetsuits, electrical insulation, and car fan belts. Its chemical inertness makes it well suited for industrial applications such as gaskets, hoses, and corrosion-resistant coatings. It can also be used as a base for adhesives. Neoprene is used for noise isolation (transformer installation). Its springy consistency makes it notoriously difficult to fold when in sheet form. Neoprene can also be used as padding in external metal cases to protect the contents while allowing a snug fit. Neoprene is also used as a contrast in some jewelery designs. ...more on Wikipedia about "Neoprene"
Nylon represents a family of synthetic polymers, a thermoplastic material, invented in 1935 by Wallace Carothers at DuPont. The first product was a nylon- bristled toothbrush ( 1938), followed more famously by women's stockings ( 1940). It is made of repeating units linked by peptide bonds (another name for amide bonds) and is frequently referred to as polyamide (PA). Nylon was the first commercially successful polymer and the first synthetic fiber to be made entirely from inorganic ingredients: coal, water and air. These are formed into monomers of intermediate molecular weight, which are then reacted to form long polymer chains. It was intended to be a synthetic replacement for silk and substituted for it in parachutes after the United States entered World War II in 1941, making stockings hard to find until the war's end. Nylon fibers are now used in fabrics and ropes, and solid nylon is used for mechanical parts and as an engineering material. ...more on Wikipedia about "Nylon"
