What is Polyethylene Terephthalate?
Polyethylene Terephthalate – Definition: Polyethylene terephthalate (PET) is a type of polyester made from the monomers terephthalic acid and ethylene glycol. It produced in both solid and liquid forms, and commonly used to make beverage bottles and other packaging materials. PET also used in fiber form, where known as polyethylene terephthalate fiber (PET fiber or PETF).
Definition of Polyethylene Terephthalate
Polyethylene terephthalate (PET) is a strong, lightweight plastic made from polyethylene terephthalate monomer. It also used to make water bottles, food containers, and other packaging materials.
Polyethylene Terephthalate Structure
Polyethylene terephthalate a type of polyester created from the combination of terephthalic acid and ethylene glycol. The terephthalic acid molecule made up of a benzene ring and a carboxylic acid group, while the ethylene glycol molecule is a simple alcohol molecule. When the two molecules combined, they form a new, larger molecule with a repeating pattern of terephthalic acid and ethylene glycol groups. This new molecule is polyethylene terephthalate.
Polyethylene Terephthalate Preparation
Polyethylene terephthalate synthesized from ethylene glycol and terephthalic acid. However ethylene glycol and terephthalic acid are reacted in the presence of a catalyst to form polyethylene terephthalate.
What are The Properties of Polyethylene Terephthalate?
- The properties of polyethylene terephthalate (PET) include being lightweight, durable, and resistant to chemicals. PET commonly used to make plastic bottles and containers for food and drink.
- Polyethylene terephthalate, also known as PET or PETE, is a type of plastic that commonly used to make water bottles, food containers, and beverage containers.
- It is a strong, lightweight plastic that is shatter-resistant and has a good barrier to oxygen, moisture, and carbon dioxide. PET also recyclable and can made into different colors and finishes.
Pet Plastic Applications
There are a number of different applications for PET plastic. Some of the most common are:
- Bottles
- Jars
- Food packaging
- Medical packaging
- Car parts
- Textiles
