High heat resistant polyamide film Uniamide®

Heat-resistant film that can handle processing temperatures from 180 to 260 degrees.
Biaxially oriented film with excellent bending resistance and shock absorption.
Transparent substrate that transmits ultraviolet rays of 320 nm or more.

Unitika Ltd.'s "High Heat-Resistant Polyamide Film Uniamide®" is a new type of biaxially oriented polyamide film made from highly heat-resistant thermoplastic aromatic polyamide (PA) resin, which was previously considered difficult to form into a film.
Even after high heat treatment such as reflow, it maintains high optical transparency for both UV and visible light.

Features of Polyamide Film Uniamide®

Heat resistance: Heat resistant up to 180-260 degrees.
Workability: Melt processing and heat fusion are possible.
Transparency: Has transparency comparable to that of polyester film.
Hydrolysis resistance and chemical resistance: Excellent chemical stability derived from the polyamide structure.
Electrical properties: As an electrical insulator, it has excellent properties, especially in the high frequency range of 1MHz or more.

Applications of Polyamide Film Uniamide®

Flexible Copper Clad Laminate (FCCL)

Transparent LED display substrate

Transparent FPCs and related substrates (FPC substrates, reinforcing films, coverlays, etc.)

Heat-resistant processing paper (release film for laminated board molding, ceramic capacitor base material, etc.)

Heat-resistant adhesive tape

UV adhesive tape base material

Speaker diaphragm

Small electronic device parts

Perovskite solar cell

Compared to conventional solar cells, perovskite solar cells are thinner, lighter and more flexible, which means they can be easily installed in places where conventional solar cells were difficult to install, and can be used anywhere, including in buildings, vehicles and mobile phones.
In addition, perovskite solar cells boast high conversion efficiency, converting sunlight into electricity more efficiently, allowing more energy to be generated in a smaller area.
