Learn More About The Properties And Applications Of High-Density Polyethylene

From bottles, bags to plastic toys, almost everything that we have around us is made up of plastic. Being one of the most common thermoplastic materials currently available, we can say that almost every sector or industry uses it for various purposes. However, of all the plastics that are found, HDPE is one of the most commonly used. When you view this plastic under the microscopic lens, you will see that this material has linear-shaped structures with very few or no branches, which provide the maximum strength/density proportion. As a consequence of its molecular composition, this material performs best in environments where moisture tolerance and cost-effectiveness are required.

What is High-Density Polyethylene?

During the Second World War, this type of plastic was created to make the high-frequency radar cables. It was successfully marketed shortly after that. Although higher-density models achieve a more rigid effect, HDPE can still differ in versatility. HDPE is manufactured at a very low temperature of 70-300°C and a 20-80 bar pressure. High-density polyethylene is elastic, waxy, moisture-resistant, and also has a very low-temperature tolerance. Let us now have a look at some important chemical properties of HDPE.

  • Higher tensile function relative to other polyethylene
  • Low-cost plastic with good manufacturing capabilities
  • Strong tolerance to low temperatures
  • Outstanding electrical insulation properties
  • Extremely poor absorption of water
  • Conformance with FDA
  • Resistant to alcohols, alkalis, dilute acids, oils, hydrocarbons, and many other solvents

What are the Applications of High-Density Polyethylene?

An amazing combination of features makes HDPE the perfect substrate for many applications across different sectors. It can be configured to satisfy the end-user specifications. Some of the very important applications of the HDPE are mentioned below.

  1. Agriculture

When talking about the agriculture industry, HDPE is used in pipes, which are prevalent in lift irrigation, pesticide spraying system, flow line irrigation, drip irrigation, and so much more. These are preferred much more than any other, as they are lighter in weight and hence transportation is easier than others.

  1. Packaging Uses 

High-Density Polyethylene is being used in a variety of packaging uses. This includes the manufacturing of crates, tubs, containers for milk and fizzy drinks, vegetable packaging caps, jerry cans, barrels, commercial bulk containers, etc. In such implementations, HDPE provides the final result with an appropriate impact capacity. It is always better to choose something like HDPE for such packaging applications, as it does not leaches out chemicals when in contact with other material.

  1. Clothing Industry

This one is very common nowadays, and many of you must have noticed it. The majority of clothing industries nowadays use HDPE in the form of poly mailers to transport their products on receiving an order from the customers. These are very good to use and can save your goods from getting damaged due to harsh weather or wear-tear, which can be caused during shipping.

  1. Fibers and Textiles

Owing to its high tensile strength, HDPE is commonly used to manufacture ropes, fishing net, sports nets, agriculture nets, industrial and decoration fabrics. This is one of the very common uses of the HDPE, and hence we can now witness the use of high-density polyethylene in this sector also.

  1. Chemical Containers

Due to its chemical-resistant qualities, HDPE is suitable for manufacturing containers for storing shampoos, sunscreen, conditioners, household cleaners, engine oil, and antifreeze solutions. The potency of these bottles is enhanced when colored or pigmented.

  1. Production of Pipe Systems

The pipe made up of high-density polyethylene has a higher molecular weight when compared to other plastics. This reinforcement, with its UV resistance, makes it appropriate for pipe and outdoor applications. The pipe grade sheet has the potential to withstand 220-180 degrees Fahrenheit. It is strong in nature and hence is resistant to most chemical reactions. This makes it effective for many industrial applications.
