Polyethylene naphthalate - Wikipedia
Polyethylene naphthalate (poly (ethylene 2,6-naphthalate) or PEN) is a polyester derived from naphthalene-2,6-dicarboxylic acid and ethylene glycol. As such it is related to poly (ethylene terephthalate), but with superior barrier properties.
Polyethylene Naphthalate (PEN) | Formula, Properties & Application
The prominent distinguishing characteristics of PEN lie in its superior chemical, thermal, mechanical, and barrier properties. This can be attributed to the chemical structure, which contains a naphthalene group that imparts rigidity and heat resistance.

General chemical structure of PENs (with R as the variable group).
The general chemical structure of PENs is shown in Fig. 1 with R as the variable group. This means that we have different types of PENs based on the R-group. These include PEN G, PEN V,...
Poly (ethylene naphthalate) (PEN) - Wiley Online Library
This article summarizes PEN's key material properties, resin preparation and fabrication, and representative examples of end-use applications published to date.
The penicillins are organic acids, read-ily soluble in different organic solvents, such as esters, chloroform or ether, but insoluble or only sparingly soluble in hydrocarbons.
