A Complete Overview and Benefits on PET Plastics
An Overview of PET Plastics
You may be thinking, “What does PET plastic stand for?” before we get into the specifics of this material. Just what is PET material? PET is an abbreviation for polyethylene terephthalate, its chemical name.
Common shorthand for PET includes PETE, PETG, APET, PETP, and PET-P. Dacron (in the US), Terylene (in the UK), and Lavsan (in Russia) are all brand names for PET plastic that are widely used interchangeably, much like “Kleenex” is the generic term for tissue paper.
PET is a versatile material because of its many useful qualities. PET has a crystal-like clarity and transparency. It can be bent without breaking, but it retains its strength and resists tearing. When molten, it takes on the form of almost any object.
The benefits of PET
Many common household items are likely constructed from PET. It’s a common material for disposable tableware, including plastic cups, water bottles, and shampoo jars. PET is also used in the form of polyester in many different textiles.
The following are some more PET uses:
- Microwaveable containers
- Containers for salad dressings
- Jars of peanut butter with pickles
- Containers for vitamins
- Solar panel lamination
- Arms for windshield wipers
- Covers for automobile engines
- Lamp holders for automobiles
Could I recycle PET plastic?
Yes! PET bottles can be recycled indefinitely. PET plastic is the most widely recycled plastic kind worldwide. Because it can be easily hydrolyzed down to monomers, purified, and re-polymerized to generate new food-grade PET, PET plastic is generally approved for recycling programs.
In the USA, PET plastic recycling has reached roughly 29.2% as of 2017. If you want to recycle your own PET plastic products, search for the number 1 among the continuous arrows to determine if the plastic is PET.
PET is safe for landfills, even if recycling is encouraged. It doesn’t break down naturally, so it won’t pollute the environment, but researchers in Japan have found bacteria that can digest PET plastic very quickly.
A Short Overview of PET’s Past Plastic
PET was originally created in the United Kingdom by the Calico Printers Association. It was initially made in 1940, when scientists were investigating phthalic acid. In 1941, a patent was issued in recognition of their work.
In the middle of the 1940s, a team of scientists at DuPont made the first use of PET in North America.
It wasn’t until the late ’50s that PET could be processed into film. Many of the modern applications of PET emerged later in the 1970s. Such as plastic bottles.

What PET Is and How It Was Made
In order to create PET plastic, terephthalic acid and ethylene glycol are polymerized. Melted PET is created by heating the two components together in a vacuum with the aid of catalysts. The polymer chains lengthen as the liquid thickens. If the polymer chain length is just right, the reaction can be halted.
Extruding and then cooling the PET results in thin strands. To create the appropriate material, the strands are pelletized before being remelted and stretched. To see how these pellets are transformed into plastic bottles, fast forward to the 28-second mark.
PET has the molecular formula (C10H8O4), and 1.38 g/cm3 is its density. It boils at 662 degrees Fahrenheit and melts at 482 degrees Fahrenheit.
