Plastics are produced in chemical plants by the polymerization of their starting materials ; which are almost always petrochemical in nature. Such facilities are normally large and are visually similar to oil refineries, with sprawling pipework running throughout.

17 Οκτ 2024 · Plastic, polymeric material that has the capability of being molded or shaped. This property of plasticity, often found in combination with other special properties such as low density, low electrical conductivity, transparency, and toughness, allows plastics to be made into a great variety of products.
26 Οκτ 2010 · The so-called PlantBottle from the Coca-Cola Co. is made by converting sugars from sugarcane farmed in Brazil into the polyethylene terephthalate (PET) plastic commonly used in the ubiquitous...
16 Μαΐ 2022 · Plastics are (mostly) synthetic (human-made) materials, made from polymers, which are long molecules built around chains of carbon atoms, typically with hydrogen, oxygen, sulfur, and nitrogen filling in the spaces.
Two main processes are used to produce plastics – polymerisation and polycondensation – and they both require specific catalysts. In a polymerisation reactor, monomers such as ethylene and propylene are linked together to form long polymer chains.

A plastic is a type of synthetic or man-made polymer that is similar to natural resins found in trees and other plants. Polymers are any of various complex organic compounds produced by polymerization—a process in which small molecules combine to make a very large chainlike molecule.
