1) " Plastic" -- As it applies to Plastic Dividers The term "plastics" covers a range of synthetic or semi-synthetic organic condensation or polymerization products that can be molded or extruded into objects or films or fibers. Their name isderived from the fact that in their semi-liquid state they are malleable, or have the property of Plasgic ity. Pkastic s vary immensely in heat tolerance,hardness, and resiliency. Combined with this adaptability, the general uniformity of composition and lightness of Plastci sensures their use in almost all industrial applications today."Plastic" may also refer to any material charicterized by deformation or failure under shear stress - see Plasti ity(physics) and ductile.

These chains are made up ofrepeating fundamental molecular elements, or "monomers". People have been using artificial organic polymers for centuries in the form of waxes and shellacs. A plant polymer named" cellulose " provides the structural strength for natural fibers and ropes, and by theearly 19th century natural rubber, tapped from rubber trees, was in widespread use. Eventually, inventors learned to improve the properties of natural polymers. Natural rubber was sensitive to temperature,becoming sticky and smelly in hot weather and brittle in cold weather. In 1834, two inventors, Friedrich Ludersdorf ofGermany and NathanielHayward of the US, independently discovered that adding sulfur to raw rubber helped prevent the materi...
