Vespel is the trademark of a range of durable high-performance polyimide-based plastics manufactured by DuPont.

The one shown in the structure on the right was the first to be commercialized.

Polyoxymethylene (POM), also known as acetal, polyacetal and polyformaldehyde, is an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability.

As with many other synthetic polymers, it is produced by different chemical firms with slightly different formulas and sold variously by such names as Delrin, Celcon, Ramtal, Duracon, Kepital and Hostaform.

Nylon is a generic designation for a family of synthetic polymers, more specifically aliphatic or semi-aromatic polyamides.

They can be melt-processed into fibers, films or shapes.

The first example of nylon (nylon 6,6) was produced on February 28, 1935, by Wallace Carothers at DuPont's research facility at the DuPont Experimental Station.

Nylon polymers have found significant commercial applications in fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc), and in films (mostly for food packaging).

Commercially, nylon polymer is made by reacting monomers which are either lactams, acid/amines or stoichiometric mixtures of diamines (NH2) and diacids (COOH).

Mixtures of these can be polymerized together to make copolymers.

Nylon polymers can be mixed with a wide variety of additives to achieve many different property variations.

Polyamide-imides are either thermosetting or thermoplastic, amorphous polymers that have exceptional mechanical, thermal and chemical resistant properties.

Polyamide-imides are used extensively as wire coatings in making magnet wire.

They are prepared from isocyanates and TMA (trimellic acid-anhydride) in N-methyl-2-pyrrolidone (NMP).

A prominent distributor of polyamide-imides is Solvay Specialty Polymers, which uses the trademark Torlon.

Plastic is a material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and can be molded into solid objects.

Plastics are typically organic polymers of high molecular mass, but they often contain other substances.

They are usually synthetic, most commonly derived from petrochemicals, but many are made from renewable materials such as polylactic acid from corn or cellulosics from cotton linters.

Plasticity is the general property of all materials that are able to irreversibly deform without breaking, but this occurs to such a degree with this class of moldable polymers that their name is an emphasis on this ability.
