The first man-made plastic was unveiled by Alexander Parkes at the 1862 Great International Exhibition in London. This material - which the public dubbed Parkesine - was an organic material derived from cellulose that once heated could be molded but that retained its shape when cooled. Parkes claimed that this new material could do anything rubber was capable of, but at a lower price. He had discovered something that could be transparent as well as carved into thousands of different shapes. But Parkesine soon lost its luster, when investors pulled the plug on the product due to the high cost of the raw materials needed in its production.

Alexander Parkes 1862 created a material called Parkesine. It was an organic material made from cellulose and heated it could be molded, and keep its shape when it cooled down.

What are the differences between polymers and plastics?

Polymers are large molecules made up of repeating units, while plastics are a type of polymer that can be molded into various shapes. Not all polymers are plastics, but all plastics are polymers. Plastics are a subset of polymers that have additional properties, such as being lightweight, durable, and easily molded.


Is plastic a polymer?

Yes, plastic is typically made from polymers. Polymers are long chains of repeating molecules, and plastics are derived from these long chains. The properties of plastics can vary depending on the specific type of polymer used in their production.


Do plastics occur naturally?

Plastics do not occur naturally; they are synthetic materials made from polymers derived from petroleum or natural gas. However, some organisms have evolved the ability to break down plastic waste, like certain bacteria and fungi, but these are not considered natural occurrences of plastic.


What makes plastics different from materials like metals and plastics?

Plastics are organic polymers made from carbon, hydrogen, and other elements, whereas metals are inorganic elements that form crystalline structures. Plastics are lightweight, have low melting points, and are highly moldable, while metals are typically heavier, have higher melting points, and can conduct electricity. Additionally, plastics are generally more resistant to chemicals and corrosion compared to metals.


What are most plastics made from?

Most plastics are made from synthetic polymers derived from petrochemicals, such as crude oil and natural gas. These polymers are formed through a process called polymerization, in which small monomer molecules are chemically bonded together to form long chains. The most common types of plastics include polyethylene, polypropylene, and polyvinyl chloride (PVC).

Are all plastics petrochemicals?

No, not all plastics are petrochemicals. A few examples of bioplastics (plastics made from biologic sources) include Polyhydroxyalkanoates, Polylactic Acids and a wider variety of starch based plastics.

How are biodegradable plastic made?

There are two types of biodegradable plastics: bioplastics and plastics made from petrochemicals. Bioplastics are made from renewable resources, like vegetable fats and oils, vegetable starch, or microbiota. Plastics made from petrochemicals are made by combining biodegradable additives which enhance biodegradation.
