Plastic - Wikipedia
Plastics are a wide range of synthetic or semisynthetic materials composed primarily of polymers. Their defining characteristic, plasticity, allows them to be molded, extruded, or pressed into a diverse range of solid forms.

PLASTIC Definition & Meaning - Merriam-Webster
The meaning of PLASTIC is a plastic substance; specifically : any of numerous organic synthetic or processed materials that are mostly thermoplastic or thermosetting polymers of high molecular weight and that can be made into objects, films, or filaments.

Plastic - Simple English Wikipedia, the free encyclopedia
Plastics are mostly petrochemicals, made from natural gas or from petroleum, a type of oil. Chemical engineers refine the petroleum which goes through a heating process. It develops ethylene and propylene, which are the chemical building blocks for many plastics. These chemicals are then combined with other chemicals to produce a polymer.

What Are Plastics? Types, Chemistry, and Health Risks
Plastics are synthetic or semi-synthetic materials made from long chains of molecules called polymers. These polymer chains are built by linking together thousands of smaller molecules, known as monomers, which are typically derived from oil, natural gas, or coal.

Plastic: Definition, Types, Properties, Applications, Advantages, and ...
Plastic is a synthetic polymer made from various organic materials that can be molded into almost any shape. Some types of plastic are clear and transparent, like that used in disposable water bottles, while others are opaque and available in a range of colors.

Plastic - Polymers, Synthetic, Recycling | Britannica
In many plastic products, the polymer is only one constituent. In order to arrive at a set of properties appropriate to the product, the polymer is almost always combined with other ingredients, or additives, which are mixed in during processing and fabrication.
