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 · In this article a brief review of the essential properties of plastics is provided, followed by a more detailed description of their processing into useful products and subsequent recycling. For a fuller understanding of the materials from which plastics are made, see chemistry of industrial polymers.
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.

Crude oil is one of the main ingredients needed to make plastic. But it’s also a fossil resource, which means there’s a limited amount of it on our planet. Happily, for one key component in plastic, called aniline, we discovered a way to create it from biomass (materials such as corn, straw and wood) instead of oil.
Plastics are made from natural materials such as cellulose, coal, natural gas, salt and crude oil through a polymerisation or polycondensation process.
