The Advantages And Disadvantages Of Polyethylene

The Advantages And Disadvantages Of Polyethylene

Polyethylene is the most well-liked and commonly used plastic in the world, used in shopping bags, toys and shampoo bottles. There are over one hundred million tonnes of the material’s resins produced yearly, which accounts for 34% of the plastics market.

Advantages
Polyethylene has many benefits which is why it has been used to make many products over the years.

Polyethylene has many useful properties which make it suitable for a number of applications. It has low energy and hardness, however could be very ductile and has good impact energy; it will stretch slightly than break.
Polyethylene is waterproof and durable, so it is longer lasting when exposed to the elements compared to different polymers.
Polyethylene is a good electrical insulator, providing electrical treeing resistance but can turn out to be electrostatically charged. Adding antistatic agents will stop this.
Depending on the thickness of the polyethylene, it could be nearly clear to opaque. The clearness of low-density polyethylene (PE) makes it suitable for packaging.
Polyethylene as HDPE may be recycled into different products, which is more price efficient than manufacturing a new product from new plastic.
Polyethylene has a melting level range of a hundred and twenty to 180 degrees Celsius for medium to high density and one hundred and five to 115 degrees Celsius for low-density polyethylene. The nice heat resistant properties enable it for use in high and low temperatures.

Disadvantages
Despite its well-likedity, polyethylene is a polymer with a couple of disadvantages which can deter manufacturers and consumers from using it.

The polymer, like many different plastics, takes a long time to break down, and as such can find yourself in landfill sites for decades, which we are running out of space for.
One other way to eliminate polyethylene is incineration, which can result in harmful gas emissions.
Polyethylene is principally extracted from petroleum or natural gas, of which there is a finite amount.
Producing polyethylene takes a considerable amount of energy and also leads to high emissions of carbon dioxide, a greenhouse gas contributing to global warming and local weather change.
Though it is technically potential to recycle the mainity of plastic polymers, there are lots of completely different types to type via, which is pricey and complex.
