The Incredible Properties of HDPE Plastic

Plastic products are all around us. Whether they are used to package groceries or act as airbags in automobiles, plastic is essential to daily life. Plastic is very useful because it is strong and lightweight, but also can be colored, bent and molded into a variety of shapes and sizes. Among the six plastics, one of the most common materials in all of manufacturing is High-Density Polyethylene, also known as HDPE. 

High-density polyethylene plastic is a flexible, see-through material that is weather-resistant and displays durability at very low temperatures. Due to these features, HDPE plastic is one of the most versatile plastics in the world. HDPE is classified by RIC code 2, which is found on the bottom of finished products like milk jugs or laundry detergent bottles.

Since HDPE has a high melting point of 120-140°C (248-284 °F), it can withstand high temperatures in outdoor or factory settings. This material is also resistant to chemicals and most solvents. So substances like dilute acids, oils, and grease do not absorb into the material. These chemical resistance properties allow HDPE to be very durable and adaptable in a variety of environments. 

According to Omnexus, HDPE also has high tensile strength properties which allow it to be resistant under tension. “It’s lightweight yet super-strong. That’s why an HDPE milk jug that weighs 2 ounces can carry a gallon of milk,” according to Plastics Make it Possible. Other notable physical properties of HDPE include its resistance to hard impact, weather, mold, mildew, rotting, and insects. 

HDPE is used in a wide variety of applications due to its robust benefits. The material is most commonly seen in the form of food and drinks packaging, which includes items like milk, ice cubes, lotions, and fruit juices. However, HDPE is also used for other applications as well. Thanks to its high tensile strength, it is a component in ropes, fishing nets, sports nets, and various types of fabrics. Another common application of HDPE is for pipes and fittings due to its chemical resistance and strength properties. These properties allow HDPE to effectively secure gas, water, sewage and protect cables. Lastly, HDPE plastic can also be used to make plastic lumber as a sustainable wood alternative.
