Everything You Need To Know About Polyethylene (PE)

Now that we know what it is used for, let’s examine some of the key properties of polyethylene. PE is classified as a “thermoplastic” (as opposed to “thermoset”), based on the way the plastic responds to heat. Thermoplastic materials become liquid at their melting point (110-130 degrees Celsius in the case of LDPE and HDPE respectively).
