Highly thermal-resistant, insulative and adhesive PI varnish for major semiconductor
customers in the world ​

New Businesses
(Powder, Display, Tube, etc.)

A diversified product portfolio of new materials 
addressing the emerging demand for
next generation applications​

EV (Electric Vehicle)

Electric motor lightweighting is crucial for increasing EV power output and enabling high-speed charging. PI Advanced Materials’ PI varnish not only reduces vehicle weight significantly, but also improves thermal stability and provides electrical insulation for reliable performance.  Our PI varnish has been adopted for use in the world’s first pure EV-exclusive platform. ​

Semiconductor

PI Advanced Materials’ semiconductor varnish is an essential material for its electrical insulation and adhesive properties during semiconductor manufacturing process. We are supplying customized varnish to major semiconductor manufacturers in the world, and are developing Photosensitive Polyimide (“PSPI”) for our semiconductor customers.

Display

The paradigm in flexible OLED panels is shifting to thinner and even more flexible panels. PI varnish for flexible OLED printed circuits with heat resistance, dimensional stability and flexibility is a solution that can potentially replace glass in the future.  PI Advanced Materials is developing differentiated products from the competition with either colorless, eco-friendly or low dielectric properties to become the first mover in the next generation display applications.

Tube​

PI varnish for printer tubing is highly heat resistant for reliable performance, and its applications are expanding from home and office printers to the next generation 3D printers. 

Product Introduction​

Leomid™ (PI Varnish)

Our PI varnish provides optimal solutions for semiconductors, displays, electric vehicles and rechargeable batteries that can help transform industries and our everyday lives.
