In this guide, we are going to take a closer look at what this material is and how it will benefit you. 

What Is Polyethylene Foam

PE foam stands for Polyethylene foam and is a type of plastic manufactured through extrusion processes. When these foam sheets are made, polyethylene is first melted. Afterward, a gas like nitrogen or carbon dioxide is injected into the polyethylene to expand the plastic and give it a foamy structure. The process creates a closed cell structure and modifies the flat foam into a three-dimensional shape. A number of different foam sheet designs can be made from polyethylene. The foam sheets can vary in thickness, density, colour, and size and have many other applications.

Polyethylene is commonly used in buildings because it has thermal properties and it can also be used for packaging because it will protect goods from impact.

Where Did Polyethylene Foam Come From

The material polyethylene dates back to 1898 when the German chemist, Hans van Pechmann, accidentally created this substance while heating diazomethane. A white, waxy substance was created and two of his colleagues studied the substance, called it polymethylene, and realized its functionality. 

This material would once again be rediscovered in 1933 by Eric Fawcett and Reginald Gibson at the Imperial Chemical Industries in England. This unique plastic was soon developed into a wide range of products including items like Tupperware that are still popular to this very day.
