How plastics are made - World Plastics Council
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.

How Is Plastic Made? A Look Inside the Process - Green Matters
2023年7月18日 · To make plastic, scientists transform raw materials, such as crude oil, into a workable polymer via heat, additives, manipulation, and time. As with most chemistry, the process usually begins with the base materials, according to the British Plastics Foundation.
Plastic | Composition, History, Uses, Types, & Facts | Britannica
2024年10月17日 · 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.
Plastic - Wikipedia
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.

2018年5月18日 · Once a completely natural product, much of today's plastic is man-made and largely dependent upon fossil fuels. From polymers to nurdles, learn how plastic i...
Plastic - Processing, Fabrication, Recycling | Britannica
2024年10月17日 · The process of forming plastics into various shapes typically involves the steps of melting, shaping, and solidifying. As an example, polyethylene pellets can be heated above Tm, placed in a mold under pressure, and cooled to below Tm in order to make the final product dimensionally stable.
How Plastics Work - HowStuffWorks
In this article, we'll examine the chemistry of plastic, how it's made, how it's used, and how it's disposed of and recycled. We'll also look at some new biologically based plastics and their role in the future of plastic.
