Image of Kaladex® 2000 hazy PEN film

Kaladex® 2000 is a hazy, uncoated polyester PEN film and is considered the standard PEN film in the Kaladex® line, whereas Kaladex® 2000L offers superior shrink resistance.

Kaladex® is a polyethylene-naphthalate (PEN) film manufactured by DuPont Teijin Films™. Originally introduced in 1992, Kaladex® PEN film is better equipped for harsh environment applications than traditional PET and has many superior properties such as strength, heat resistance, anti-hydrolysis, dimensional stability, low oligomer extraction, etc. It also serves as a cost-effective alternative to specialty engineered films like polyimides. Kaladex® is used for high-density data storage tapes, IC card, optical applications, flexible printed circuitry (FPC), automotive end uses, and electrical insulation components in applications such as capacitors and batteries.
