What’s the difference between LDPE and HDPE?

Both materials derive from polyethylene (PE), which is the most popular plastic in the world, used in everything from supermarket bags to bullet-proof vests. PE is a thermoplastic created by polymerising ethylene. This can be done in different ways that produce LDPE and HDPE. In other words, these polymers have different properties because of the structure of their molecules.

The differences in properties range from tensile strength, ductility, density and vary further depending on the application LDPE or HDPE is being used for, read more in this handy guide from Essentra Components.
