plastic

1. any one of a large number of synthetic usually organic materials that have a polymeric structure and can be moulded when soft and then set, esp such a material in a finished state containing plasticizer, stabilizer, filler, pigments, etc. Plastics are classified as thermosetting (such as Bakelite) or thermoplastic (such as PVC) and are used in the manufacture of many articles and in coatings, artificial fibres, etc.
2. Fine arts
a. of or relating to moulding or modelling
b. produced or apparently produced by moulding
3. Biology of or relating to any formative process; able to change, develop, or grow

Plastic

Any of the various synthetic complex organic compounds produced by polymerization; can be molded, extruded, or cast into various shapes or drawn into fibers.

acrylic fiber

A synthetic polymer fiber.

fiberglass

The generic term for a material consisting of extremely fine filaments of glass that are mixed with a resin to give the desired form in a mold. Layers of this combination are laid or sprayed into the mold.

nylon

A class of thermoplastics characterized by extreme toughness, strength, and elasticity and capable of being extruded into filaments, fibers and sheets.

plastic

[′plas·tik]
(materials)
A polymeric material (usually organic) of large molecular weight which can be shaped by flow; usually refers to the final product with fillers, plasticizers, pigments, and stabilizers included (versus the resin, the homogeneous polymeric starting material); examples are polyvinyl chloride, polyethylene, and urea-formaldehyde.
(mechanics)
Displaying, or associated with, plasticity.

plastic

1. A natural or artificially prepared organic polymer of low extensibility, as compared with rubber; can be molded, extruded, cut, or worked into a great variety of objects, rigid or nonrigid, relatively light, which are formed by condensation polymerization and by vinyl polymerization; plastics.
