How does plastic make our lives easier?
Plastics are used to make bicycle helmets, child safety seats and airbags in automobiles.
They’re in the cell phones, televisions, computers and other electronic equipment that makes modern life possible.
They’re in the roofs, walls, flooring and insulation that make homes and buildings energy efficient..
Why plastic is used instead of metal?
In industrial applications, plastic offers maneuverability and handling benefits when compared with metal — think of the large sliding compartment doors in shipping containers. They can provide the same strength and rigidity (more on that below), with a much lower weight, making them considerably easier to move.
What are the advantages and disadvantages of metals?
Advantages and Disadvantages of metals commonly used in ManufacturingAdvantages: The most abundant metal in the Earth’s crust, Aluminium is relatively soft, durable, lightweight, ductile and malleable metal. … Disadvantages: It’s not particularly strong and is expensive compared to steel of the same strength.More items…
What is the advantage and disadvantage of plastic?
What are the advantages and disadvantages of using plastic? The benefits of plastics: the production criteria are durable, low cost, water-resistant, lower energy and heavy chemicals and are lightweight.
How does replacing of metal parts with plastic parts in Aircrafts help?
Plastics have replaced aluminum as a more affordable, more lightweight material option, useful for both the interior design and functionality of airplane cabins. Plastic can be used for everything from overhead luggage storage compartments to ductwork to ventilation fan rotors.
Do we need plastic?
Plastic is durable and provides protection from contaminants and the elements. … It reduces food waste by preserving food and increasing its shelf life. It protects food against pests, microbes and humidity.
What are the disadvantages of plastic use?
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.
Is stainless steel renewable?
The non-renewable resources used to make steel, like minerals and fossil fuels, are not wasted because the steel will be used forever. This is truly sustainable. Steel is truly recyclable and is truly recycled. … Unlike other materials, steel is only used – never consumed.
What are three advantages of using plastic?
The advantages of plastics: It is durable, low cost, water resistant, lesser energy and heavy chemicals requirements in manufacture and are light weight.
How plastic is useful to us?
Plastic is very useful because it can be coloured, melted, shaped, squashed, rolled into sheets or made into fibres plastics. Plastic also are hygienic and it is not poison to our bodies. Plastic is used made ropes that are very strong and fishing lines, glues and paints.
Which is better metal or plastic?
More heat-resistant – metals tend to have a higher melting point than plastics. Operating temperature – metal can be used in extreme hot and cold temperatures. Metal has a higher tensile strength than plastic. Stainless steel is durable and easy to clean.
Does plastic last longer than metal?
Product Life: The life span is longer for plastics than metals in many applications. Cost: The cost of raw material can be appreciably less. With a less labor intensive process, plastic molding can also save energy, labor, and production time vs.
Is plastic stronger than metal?
Plastics developed from organic materials have been researched for many years now. In 1941, Henry Ford used industrial hemp plastic to construct a car. The material is at least 2.5 times stronger than steel. … In addition to this, recent research shows that the material is completely biodegradable.
What are the advantages of using metal?
Metals generally provide the following advantages over plastic fabrication: Heat resistance: Metals typically have a higher melting-point and are less likely to degrade under elevated temperatures. Improved strength: Metal grades tend to be stronger, harder, and more durable than their plastic counterparts.
What is the disadvantage of plastic?
Harmful Nature Disposable plastics used in packaging foodstuff meant for human consumption contain harmful compounds. Improper disposal of these packaging products leads to these harmful compounds finding their way to water bodies, where they dissolve over a long time due to their non-biodegradable nature.
What is a disadvantage of steel?
Steel is an alloy of iron. This makes it susceptible to corrosion. In high temperatures, steel loses its properties. …
What are the disadvantages of sheet metal?
However, the disadvantages are that forming times are long, production rates are low, and the parts are not suitable for high-temperature use.
Is plastic cheaper than aluminum?
PLASTIC STRIKES BACK Simple economics is a major factor; aluminum is more expensive than plastic – the raw material cost for a can is about 25-30% higher than a PET bottle of a similar volume, according to analyst Uday Patel at consultancy Wood Mackenzie.
What is plastic metal?
Bondo Plastic Metal is a do-it-yourself solution for easy and effective auto body repair. Fill and seal seams and cracks in metal and other surfaces right from the tube – no mixing required.

Why is plastic harmful?
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 are the positive impacts of plastic?
The Positive Impact of Plastics Lightweight plastics packaging saves fuel and decreases emissions during transportation. Plastic water supply systems and plastic storage tanks provide clean water free of heavy metals. Plastic products for medical applications contribute to improved health and wellness.
