Plastic

Plastic is a versatile material comprising a wide range of synthetic or semi-synthetic organic compounds that are malleable and can be molded into solid objects. The term 'plasticity' refers to the ability of materials to deform irreversibly without breaking, which is a key characteristic of moldable polymers.

Plastics are typically organic polymers with high molecular mass and often include other substances. While most plastics are synthetic and derived from petrochemicals, there are variants made from renewable materials like polylactic acid from corn and cellulosics from cotton linters. Due to their low cost, ease of manufacture, versatility, and resistance to water, plastics are employed in numerous products, ranging from everyday items like paper clips to complex applications such as spacecraft. This extension provides a thorough reference for understanding plastics in various contexts.
