Polyethylene and Polypropylene: What’s the Difference?

We’ve talked a lot about polyethylene pipe, but for those that are just getting started with the many benefits of HDPE, there may be some confusion. There is also polypropylene, a word that sounds somewhat like polyethylene yet has its distinct characteristics.

Similar to polyethylene, polypropylene is indeed a type of plastic. However, unlike polyethylene, polypropylene is able to mold after it has reached a certain temperature. Once the material has cooled down, it will once again become a solid. It can, therefore, be used as a type of plastic or it may have applications as a fiber. Its melting pot is also significantly higher than polyethylene and it is known for its strong stability. For example, when used as a hinge, this plastic can opened and closed numerous times without issue.

In terms of physical properties, polyethylene and polypropylene have lots of similarities. However, the former is, as mentioned, better able to withstand certain temperatures like cold, for example. Polyethylene is also well-suited for use as an electrical insulator.
