Overview

This is a super heat-resistant polyimide film with a unique composition made from BPDA (biphenyltetracarboxylic dianhydride), which is produced in-house by UBE Corporation.

It has particularly excellent dimensional stability, low water absorption, and chemical resistance.
NEW In addition to the basic grade Upilex®,
we offer a wide lineup of molded grade Upilex®-RN and functionally enhanced grades.

Features

  1. 1.High heat resistance

    The product has normal and long-term heat resistance in the 300°C class, and is suitable for high-temperature processes up to 500°C.

  2. 2.High mechanical properties

    Excellent toughness and abrasion resistance.
    Thin films can be used for applications that require high strength.

  3. 3.Chemical resistance

    Excellent chemical resistance to organic solvents, gasoline, automotive oil, alkalis, acids, etc.

  4. 4.High Performance Technology

    UBE's proprietary polyimide film surface layer composition is functionalized with our proprietary technology to develop even more highly functional and high-value-added films.

Applications

  • (electrical circuit) substrate

  • Thin Devices

  • Display Substrate

  • ATM Components

  • Speaker cone

Lineup

Based on the strengths of the basic grade Iupilex®-S,
we have developed a variety of film grades by utilizing our polyimide film surface functionalization technology,
which are widely used in various applications.
