Polymers & Plastics

Polyester amides

1979 BCE

Polyether block amide or peba is a thermoplastic elastomerIt.It is a block copolymer obtained by polycondensation of a carboxylic acid polyamide with an alcohol termination polyether

Kevlar

1966 BCE

Kevlar or polyparaphenylene terephthalamide is a polyamide first synthesized in 1965 by Polish-American chemist Stephanie Kwolek, who worked for DuPont. Obtaining Kevlar fibers was complicated, highlighting the contribution of Herbert Blades, who solved the problem of which solvent to use for processing

Tupperware

1949 BCE

Tupperware is normally used to do kitchen and home products.Is often used generically to refer to plastic or glass food storage containers with snap close lids.

Teflon

1938 BCE

Polytetrafluoroethylene, better known as Teflon, is a polymer similar to polyethylene, in which hydrogen atoms have been replaced by fluorine atoms. The chemical formula of the monomer, tetrafluoroethene, is CF2 = CF2. The polymer formula is shown in the figure.

Polyethylene

1936 BCE

Polyethylene or polythene is the most common plastic in use today. It is a linear, man-made, addition, homo-polymer, primarily used for packaging. As of 2017, over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market

Nylon

1935 BCE

Nylon or nylon is a synthetic polymer that belongs to the group of polyamides. Nylon is an elastic and resistant textile fiber, it is not attacked by moths, it does not require ironing and is used in the manufacture of stockings, fabrics and knits, also bristles and lines.

Neoprene

1931 BCE

Neoprene or polychloroprene is a family of synthetic rubbers that are produced by polymerization of chloroprene. Neoprene has good chemical stability and maintains flexibility over a wide temperature range.

Polyvinyl chloride (PVC)

1926 BCE

Polyvinyl chloride is the world's third-most widely produced synthetic plastic polymer. About 40 million tons of PVC are produced each year.

Cellophane

1920 BCE

Cellophane is a thin, transparent sheet made of regenerated cellulose. Its low permeability to air, oils, greases, bacteria, and water makes it useful for food packaging.

Rayon

1907 BCE

Rayon is a man-made and regenerated cellulosic fiber.

Bakelite

1907 BCE

Bakelite is the first plastic made from synthetic components. It is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde.

Celluloid

1860 BCE

Celluloids are a class of materials produced by mixing nitrocellulose and camphor, often with added dyes and other agents. Once much more common, celluloid's common contemporary uses are table tennis balls, musical instruments, combs, office equipment, and guitar picks.

Nitrocellulose

1845 BCE

Nitrocellulose is a highly flammable compound formed by nitrating cellulose through exposure to nitric acid, or to a mixture of nitric acid and another acid, usually either hydrochloric acid or sulfuric acid, or to another powerful nitrating agent.
