Plastic is a material consisting of any of a wide range of
synthetic or semi-synthetic
organics that are
malleable and can be
molded into solid objects of diverse shapes. 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 partially natural.
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.
