What is the main raw material for plastic?
Plastics are made from natural materials such as cellulose, coal, natural gas, salt and crude oil through a polymerisation or polycondensation process. Plastics are derived from natural, organic materials such as cellulose, coal, natural gas, salt and, of course, crude oil.
What properties of plastic make them the material of choice?
Plastics generally have: resistance to corrosion and chemicals, low electrical and thermal conductivity, high strength-to-weight ratio, colors available in a wide variety and transparent, resistance to shock, good durability, low cost, are easy to manufacture, resistant to water and have low toxicity.
What are the pros and cons of plastic?

Why is plastic bad for Earth?
Plastic pollution on land poses a threat to the plants and animals – including humans who are based on the land. … Chlorinated plastic can release harmful chemicals into the surrounding soil, which can then seep into groundwater or other surrounding water sources and also the ecosystem of the world.
What would happen if everyone stopped using plastic?
Plastic bags are produced using petroleum, natural gas and other chemicals. Its production is toxic to the environment. … If we eliminated plastics from our lives, we’d save hundreds of marine species from entanglement and plastic ingestion.
What are the disadvantages of plastics?
The demerits of plastic are: Plastic bags thrown carelessly on roads get into drains and the sewer system and choke them. … Plastics give out harmful gases upon heating or burning which causes air pollution and many health problems. Plastic bags filled with garbage is thrown away in the open.
Why do so many people use plastic?
Plastic is: … Durable: because plastic packaging is so durable, plastic packaging can be very thin. This means it uses fewer resources and takes up less space for transport which means fewer trucks, trains or planes are needed to transport it. Versatile: plastics can be transformed in many different ways.
What chemicals are used to make plastic?
The term “plastics” includes materials composed of various elements such as carbon, hydrogen, oxygen, nitrogen, chlorine, and sulfur. Plastics typically have high molecular weight, meaning each molecule can have thousands of atoms bound together.
What are three properties of plastic?
Plastics are generally low cost, easy to manufacture, durable, strong for their weight, electrically and thermally insulative, and resistant to shock, corrosion, chemicals, and water.
What is the main cause of plastic pollution?
But what are the causes of plastic pollution? Negligence is the main cause. In fact, it is estimated that 80% of marine litter comes from land. This pollution comes mainly from household waste, which is poorly recycled, dumped in landfills or abandoned in nature.
Do we really need plastic?
It is cheaper, but there are other good reasons we have started relying more and more on plastic packaging. … Plastic is durable and provides protection from contaminants and the elements. It reduces food waste by preserving food and increasing its shelf life.
Who invented plastic?
Alexander ParkesPlastics: a story of more than 100 years of innovation Finally, the wide range of completely synthetic materials that we would recognise as modern plastics started to be developed around 100 years ago: One of the earliest examples was invented by Alexander Parkes in 1855, who named his invention Parkesine.
Is paper a raw material?
The process of papermaking uses raw materials including water, energy, chemicals and wood chips (1), that contain cellulose. Cellulose is the fiber component of wood, and exists naturally in most plant life.
How harmful is plastic?
Plastic affects human health. Toxic chemicals leach out of plastic and are found in the blood and tissue of nearly all of us. Exposure to them is linked to cancers, birth defects, impaired immunity, endocrine disruption and other ailments.
