  • Nitrocellulose - Paul Vieille

    Nitrocellulose is a product obtained by nitration of pure cellulose, which is used, according to its characteristics, as a base for gunpowder, dynamite, explosive jellies or paints.
    Cellulose nitrate was discovered by Christian Schönbein in 1845, like many things in science, it happened by chance, when drying with a cotton cloth (cellulose fiber) with the remains of a mixture between sulfuric and nitric acid

  • Celluloid - Alexander Parkes

    Celluloid. Originally the trade name, and today the common name of a synthetic plastic product of the mixture of cellulose nitrate, or pyroxylin, with pigments and fillers in a solution of camphor and alcohol.
    When heated, the celluloid becomes flexible and malleable, and can be molded in numerous ways. Once cooled and dry, the material becomes hard. The celluloid is transparent and colorless, and the paste can be colored, rolled and molded into certain shapes.

  • Bakelite - Leo Baekeland

    Bakelite was the first fully synthetic plastic substance, created in 1907 and named in honor of its creator, the Belgian Leo Baekeland (the Nobel Prize in Chemistry Adolf von Baeyer experimented with this material in 1872 but did not complete its development). It was also one of the first known thermostable synthetic polymers. It is a phenoplastic that still has interesting applications today

  • Rayon - Bombyx

    Rayon is a fiber manufactured from regenerated cellulose. It is a cellulose fiber previously solubilized and subsequently regenerated. It is a very versatile fiber and has the same properties in terms of comfort of use as other natural fibers, being able to imitate the touch of silk, wool, cotton or linen.

  • Cellophane - Jacques E. Brandenberger

    Cellophane. Thin and flexible sheet, as a transparent paper, made of solidified viscose, which is mainly used to wrap objects and preserve them from moisture.
    Cellophane was invented by Swiss textile engineer Jacques E. Brandenberger in 1908. After seeing that wine was spilled on the tablecloth of a restaurant, Brandenberger had the idea of ​​producing a transparent coating for the fabric that made it waterproof.

  • Polyvinyl chloride ( PVC ) - Eugen Baumann and Waldo Semon

    Polyvinyl chloride: It is one of the most studied and used by man polymers for its development and comfort, given that due to its wide versatility it is used in areas as diverse as construction, energy, health, food preservation and everyday items. , among others.
    The chlorine atom attached to each carbon atom confers mainly amorphous characteristics and prevents its recrystallization

  • Neoprene - Wallace Carothers

    Neoprene (or polychloroprene). Neoprene is an artificial chemical that is used as a substitute for rubber. Its chemical formula is C4H5CL and has characteristics so similar to those of natural rubber, which can even fulfill the same functions. In addition to behaving as such, the neoprene is even more resistant to sunlight, oils and fats than rubber itself. Neoprene is obtained from chlorine butadiene, an element that originates from another element called acetylene.

  • Nylon and Neoprene - Paul J. Flory

    Nylon is a synthetic polymer belonging to the group of polyamides. It is a manufactured fiber which is formed by repetition of units with amide bonds between them. The substances that make up nylon are long chain synthetic polyamides that have amide groups (-CONH-) as an integral part of the polymer chain. There are several different versions of Nylons, with nylon 6.6 being one of the best known.

  • Polyethylene - Hans Von Pechmann

    Polyethylene. It is the most popular plastic in the world and probably the polymer that is most seen in daily life. The manufacture of polymers of ethylene consumes 60% of the ethylene that is produced.

  • Teflon - Hans von Pechmann

    Teflon It is the trade name registered by the North American transnational DuPont to identify a type of fluorinated polymer, chemical name "polytetrafluoroethylene" or "PTFE", formed by a succession of molecules composed of two fluorine atoms (F) and one of carbon ( C), which resulted in an inert and non-stick material.

  • Tupperware - Earl Tupper

    Los materiales plásticos Tupperware utilizados han pasado un estricto proceso de selección antes de su fabricación. Previamente, los productos se prueban contra impactos, detergentes, rayos ultravioleta, resistencia a temperaturas en función de su uso y, por supuesto, para su contacto con alimentos.

  • Kevlar - Stephanie Kwolek

    Kevlar Obtaining Kevlar fibers was complicated, highlighting the contribution of Herbert Blades, which solved the problem of which solvent to use for processing. Finally, DuPont began marketing it in 1972. It is very resistant and its mechanization is very difficult. Kevlar is a fiber that combines a reduced weight with extraordinary mechanical resistance.

  • Polyester Amides - John Rex Whinfield and James Tennant Dickson

    Polyester. British chemists John Rex Whinfield and James Tennant Dickson, employees of the Calico Printer`s Association of Manchester patented the "poly (ethylene terephthalate)" (also called PET or PETE) in 1941 by continuing Wallace Carothers' first investigations.
