Polyethylene naphthalate or PEN is a polyester derived from naphthalate-2, ethylene glycol, and 6-dicarboxylic acid. Although polyethylene naphthalate is similar to terephthalate (PET) chemically, it is more temperature resistant and a better barrier compared to PET. It features excellent physical properties such as good thermal conductivity, dimensional stability, dielectric strength, excellent hydrolysis resistance, low thermal shrinkage, and high mechanical strength.
