The PENSTAR family offers a range of high-class Polyethylene Naphthalate products and its copolyesters for technically demanding applications.

Polyethylene Naphthalate (PEN) is a high-performance polymer known for its superior thermal, mechanical, and optical properties, making it ideal for advanced applications in electronics, packaging, and high-performance films. Compared to PET, PEN offers superior thermal stability, barrier properties, dimensional control, and optical performance, making it the preferred choice for high-performance applications.

• A more rigid molecular structure for enhanced strength and dimensional stability
• A higher glass transition temperature (121°C vs. 78°C) for improved heat resistance
• Better gas and moisture barrier performance due to tighter molecular packing
• Improved dimensional control from its slower crystallization rate
• Greater stretchability and orientation, leading to better mechanical and optical film properties
• Enhanced optical performance with higher refractive index anisotropy
• Superior processability, particularly in demanding film and display applications
