Yes, polythene is a man-made material. It is a type of plastic that is produced from ethylene, a chemical derived from petroleum.
The polymer "polythene".
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.
This monomer is ethene (or ethylene) - C2H4.
The main difference between Ordinary Polythene & Biodegradable polythene is: * Ordinary polythene takes an around 100 + years to degrade... * Biodegradable/Degradable polythene degrades or biodegrades in around 5 yrs depending on how it's made and how its disposed. However, biodegradation starts in the presence of sunlight, moisture, mechanical stress and/or microorganisms...

Petrol cannot be directly prepared from polythene. Polythene is a type of plastic made from ethylene, while petrol is a refined product derived from crude oil. The process of converting polythene back into its original components for potential further refining into fuel is complex, involves high temperatures, and is not commonly practiced on a large scale.

Polythene (polyethylene) sheet is made from polymerized ethylene monomer.
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.
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.
Yes, like Polyester, Polythene
Polythene is a compound made up of repeating units of ethylene monomers. It is not an element or a mixture, but a polymer compound.
Hefty sandwich bags are made up of polythene.
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.
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.
