Polyethylene is the most well-liked and commonly used plastic in the world, utilized in shopping bags, toys and shampoo bottles. There are over 100 million tonnes of the material’s resins produced yearly, which accounts for 34% of the plastics market.
Polyethylene has many benefits which is why it has been used to make many products over the years.
Polyethylene has many helpful properties which make it suitable for several applications. It has low strength and hardness, but is very ductile and has good impact power; it will stretch fairly than break.
Polyethylene is water-resistant and durable, so it is longer lasting when exposed to the weather compared to different polymers.
Polyethylene is a good electric insulator, offering electric treeing resistance but can change into electrostatically charged. Adding antistatic agents will prevent this.
Depending on the thickness of the polyethylene, it might be almost transparent to opaque. The clearness of low-density polyethylene (PE) makes it suitable for packaging.
Polyethylene as HDPE may be recycled into other products, which is more price efficient than manufacturing a new product from new plastic.
Polyethylene has a melting level range of 120 to a hundred and eighty degrees Celsius for medium to high density and a hundred and five to a hundred and fifteen degrees Celsius for low-density polyethylene. The good heat resistant properties enable it for use in high and low temperatures.
Despite its standardity, polyethylene is a polymer with a few disadvantages which can deter producers and consumers from utilizing it.
The polymer, like many different plastics, takes a very long time to break down, and as such can find yourself in landfill sites for decades, which we are running out of area for.
Another way to eliminate polyethylene is incineration, which may end up in dangerous gas emissions.
Polyethylene is mainly extracted from petroleum or natural gas, of which there's a finite amount.
Producing polyethylene takes a large amount of energy and likewise leads to high emissions of carbon dioxide, a greenhouse gas contributing to global warming and local weather change.
Although it is technically possible to recycle the keyity of plastic polymers, there are a lot of totally different types to kind through, which is expensive and complex.
