What is Polyethylene and Where Is It Use?
History of Polyethylenes
The history of polyethylene goes back almost a hundred years, to the 1930s. It was discovered in 1933 by two employees of Imperial Chemical Industries, a UK-based chemical company, Eric Fawcett and Reginald Gibson. The chemical representation of polyethylene, which is a thermoplastic frequently used in the production industry, is (-CH2CH2-)n.
What is Polyethylene?
Polyethylene is a thermoplastic polymer produced at high temperature and pressure, obtained from monomerized ethylene and having different usage areas. Known for being a durable and strong thermoplastic, polyethylene is one of the most preferred raw materials in the production of plastics.
What Are The Properties of Polyethylenes?
Polyethylenes can be seen in different colors and appearances. Polyethylenes, which can be colored with white, blue, brown, black and orange colors, are extremely durable and strong thermoplastics. Known for their resistance to external impacts, polyethylenes are also extremely resistant raw materials against harmful UV rays. Polyethylenes, which has the ability to insulate electricity, also has high strength. They are also frequently used in the packaging of liquid products. In light of all these, when the usage rates in the world are examined, it is seen that the most used thermoplastic is polyethylene.
Apart from these features, some of the features of polyethylene are as follows;
-Moisture and water resistant
-Extremely strong in packaging of acidic chemicals
-Easy to process
-Abrasion resistant
-Resistant to heat and cold
-Does not carry bacteria
-Lightweight and easy to use
-High resistance to cracking
Usage Areas of Polyethylenes
Polyethylenes have different usage areas according to their structures and production methods. It is frequently used in the construction industry, plastic industry and cosmetics industry. If we look at these sectors a little more specifically, it can be used in the production of industrial water tanks, toys, playgrounds, cans and household goods. However, the usage areas are not limited to those listed only. It is frequently used in the paper industry, in the production of pumps and bellows, in the production of artificial body parts, in the production of machine parts, in the production of wheels and in the production of automotive parts.
Polyethylene Types
Polyethylenes can be found in different types according to their chain structure and industrial usage areas. These polyethylene types are as follows;
- Ultra High Molecular Weight Polyethylene
- Ultra Low Molekül Ağırlıklı Polietilen
- High Molecular Weight Polyethylene
- Low Density Polyethylene
- Very Low Density Polyethylene
- Linear Low Density Polyethylene
- Medium Density Polyethylene
- High Density Polyethylene
Considering the sector average, the most used polyethylene varieties in the production industry; It is seen that it consists of high-density polyethylene, low-density polyethylene and linear low-density polyethylenes.
Where to Buy Polyethylene?
There are many factors to consider when purchasing polyethylene. One of them is the quality of the polyethylene to be purchased. Unused production polyethylenes should be preferred instead of recycled polyethylenes. Another factor is seller reliability. It has been observed that negative experiences are frequently experienced in purchases made in large quantities from unproven intermediaries. In this sense, Sümer Petrokimya is one of the most reliable polymer and chemical raw material suppliers in Turkey. You can take a look at the polyethylene category of Sümer Petrokimya, which attaches great importance to high customer satisfaction in pre-sales, sales and after-sales processes, and reach our experts from the sales support page for the product you are interested in.
