The World’s First Ultra-Thin Polyimide Film at Just 4 Micrometers (μm)!

The world's thinnest ultra-film :

By producing this 4-micrometer ultra-thin polyimide film, following the successful commercialization of a 5-micrometer ultra-thin film, PI Advanced Materials has demonstrated its unrivalled film-making technology on a global scale. The development is expected to provide a competitive edge to the company in the market for lightweight products, essential to the growing trend of slimmer electronic devices, including smartphones.

Essential material in the electronics 

Polyimide films are essential materials in the electronics, aerospace, and automotive industries due to their exceptional heat resistance and strength. While most polyimide films are produced in thicknesses ranging from 12.5 to 25 micrometers, PI Advanced Materials stands out as the only manufacturer worldwide offering a 4-micrometer polyimide film produced by a non-stretching process.

Lightweight and compact devices

These ultra-thin polyimide films are essential for developing lightweight, compact electronic devices such as smartphones, high-performance displays, and wearable technology. They are expected to provide innovative solutions across various applications, including battery materials. Notably, the 4-micrometer film, which is approximately 1/25th the thickness of a human hair, is both lightweight and flexible, making it ideal for miniaturizing components for flexible display panels. These ultra-thin polyimide films can dramatically reduce the thickness and weight of high-definition display panels while enhancing electric vehicle battery efficiency through weight reduction. Starting next year, it will also be applied to improve the heat resistance and durability of smartphones, tablets, and wearable devices.
