What is PET Stands For?
PET is a versatile and widely used plastic material. It is also known as polyethylene terephthalate. PET is a thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, and thermoforming for manufacturing, and in combination with glass fibre for engineering resins.
History of PET
1. PET was first synthesized in 1941 by John Rex Whinfield and James Tennant Dickson in the UK.
2. It was patented in 1946 by Imperial Chemical Industries (ICI).
3. The first commercial production of PET began in 1953.
Properties of PET
1. PET is a strong and lightweight material.
2. It is resistant to chemicals and heat.
3. PET is transparent and has a low gas permeability.
Uses of PET
1. PET is used in the manufacture of food and beverage containers.
2. It is also used in the production of clothing fibres, such as polyester.
3. PET is used in the manufacture of thermoformed products, such as trays and clamshells.
Environmental Impact of PET
1. PET is a non-biodegradable material.
2. It can take hundreds of years to decompose.
3. PET can accumulate in the environment and can pose a threat to wildlife.
Conclusion
PET is a versatile and widely used plastic material. It has a number of desirable properties, including strength, lightness, and resistance to chemicals and heat. However, PET is also a non-biodegradable material and can have a negative impact on the environment. As a result, there is a growing interest in developing biodegradable alternatives to PET.
