Polythene, also known as polyethylene, was first synthesized by German chemist Hans von Pechmann in 1898. However, it was not until 1933 that the first practical method for producing polythene was developed by British chemists Eric Fawcett and Reginald Gibson at Imperial Chemical Industries (ICI). Their work led to the commercialization of polythene, which has since become one of the most widely used plastics.

What is polythene rod made of?
The polymer "polythene".
What type of material is a sheet of polythene?
Polythene (polyethylene) sheet is made from polymerized ethylene monomer.
Is polythene man made?
Yes, polythene is a man-made material. It is a type of plastic that is produced from ethylene, a chemical derived from petroleum.
Is polythene made of carbon and hydrogen?
Yes, polythene is made of repeating units of ethylene, which is composed of carbon and hydrogen atoms. The chemical formula for polythene is (C2H4)n, where n represents a large number of repeating units.
What is the state of matters of polythene?
Polythene is a type of plastic that is non-biodegradable, meaning it does not break down easily in the environment. This has led to issues with pollution and waste management, as polythene items can persist in the environment for a long time. Efforts are being made to reduce the use of polythene and find more sustainable alternatives.
Is polythene a mixture compound or element?
Polythene is a compound made up of repeating units of ethylene monomers. It is not an element or a mixture, but a polymer compound.
Are plastic made from chemicals?
Yes, like Polyester, Polythene
What are hefty sandwich bags made of?
Hefty sandwich bags are made up of polythene.
Is polythene natural?
Polythene, also known as polyethylene, is a synthetic polymer made from ethylene, a compound derived from natural gas and petroleum. It is not a natural material as it is man-made through chemical processes in industry.
Is polythene toxic?
Polythene itself is not inherently toxic, as it is a type of plastic made from polymers. However, when polythene is not disposed of properly and ends up in the environment, it can release harmful chemicals and pollutants that can be toxic to organisms. It is important to recycle and properly dispose of polythene to prevent environmental harm.
What is the difference between Bakelite and polythene in nature?
Bakelite is a thermosetting plastic, meaning it cannot be reshaped once molded, while polythene is a thermoplastic that can be melted and reshaped multiple times. Bakelite is a poor conductor of electricity, whereas polythene is an insulator. Bakelite is more rigid and heat resistant compared to polythene.
What is more flexible aluminium or polythene?
Polythene.
