  • A solid material which can flow into a given desired shape through the application of heat and/or pressure. A plastic is ordinarily synthetic, and its chief constituent is usually a polymerized organic molecule, such as polyvinyl chloride. The two main classifications for plastics are thermosetting and thermoplastic. Plastics are electrical insulators, and have many applications in electronics, including their use in components such as capacitors, recording media such as floppy disks and optical disks, optical fibers, lenses, IC packages, in frames, as an encapsulant, and for tubing, among many others.

Origin & History of “plastic”

Plastic is etymologically a ‘mouldable’ substance. The word comes via French plastique and Latin plasticus from Greek plastikós ‘fit for moulding’, a derivative of the verb plássein ‘mould’ (source also of English plasma (18th c.) and plaster). Up until the 20th century its main use in English was as an adjective, meaning ‘pliable’. The first record of its use for a ‘synthetic material made from organic compounds’ comes from 1909. The trade-name Plasticine was coined from it in the 1890s.
