About Plastic Products and Plastic Pollution | US EPA
Plastic products are generally versatile, durable and lightweight. Plastic products are prominent in the construction, transportation, and packaging industries. Plastic innovations contributed to many life-saving products that revolutionized the health care industry.

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.

History and Future of Plastics - Science History Institute
Plastic is a word that originally meant “pliable and easily shaped.” It only recently became a name for a category of materials called polymers. The word polymer means “of many parts,” and polymers are made of long chains of molecules. Polymers abound in nature.

What is Plastic? Definition and Explanation - Plastic Online
What is plastic? Plastic is a man-made material that may be moulded and formed into solid objects. It is crafted from long chains of molecules known as polymers. Plastics can bend and exchange form without breaking easily. They are very flexible and may be moulded into many forms and merchandise.
