We can also provide Unifiner in film type available.
Unifiner film has higher heat resistance, transparency, electrical properties and flexibility. It is suitable for various applications that require high heat resistance.

Approaching Applications

Film capacitor

Its high heat resistance and electric properties (dielectric breakdown strength) contribute to create a high heat resistance ability for Film capacitor.

Optical film

- ITO transparent conducting films -

Unifiner Film has a compatible advantage in both of high heat resistance and transparency. It can expect to be used for the applications to base film for optical film such as touch panel.

Recommendation : M-2000H 25µm film

TransparencyHeat resistance

- OCA base film -

It can expect the following effects when Unifiner Film is used for OCA base film as a transparent-high heat resistance base material.

Process reduction
  • Detaching process of the heavy release film such as PET film
  • Attaching process of OCA onto Unifiner
Waste materials reduction
  • No need to use release film (heavy release) such as PET film
