PI Film from Hyosung Chem arrives as a quiet workhorse: a thin, amber sheet that bends between your fingers yet shrugs off soldering heat on a crowded circuit board. In the hand it feels smooth and slightly waxy, more technical than household plastic.
What PI Film is built for
PI Film from Hyosung Chem is a polyimide-based film engineered as a substrate for flexible printed circuit boards, high-density interconnects and display modules. It targets applications where temperatures above 200°C and tight bending radii would destroy standard polyester films.
The material is typically produced in precise thickness grades, often between tens and a few hundred micrometers, giving process engineers room to tune stiffness and weight. On a production line, rolls of PI Film run through coating and etching steps to build copper traces and protective layers.
Background on Hyosung Chemical shares
Hyosung Chem uses PI Film and other advanced materials to position itself as a supplier to electronics and battery manufacturers in Asia and beyond.
Where engineers lean on it
In a flex PCB stack, PI Film usually sits as the base layer under copper foil, adhesive and coverlay. Its heat resistance lets assemblers push reflow profiles and maintain dimensional stability, which matters when fine-pitch components line up across folding sections.
Display makers and battery-pack designers also tap PI Film for insulation and mechanical support in tight spaces. Because the film can be cut and laser-processed cleanly, it lends itself to intricate apertures around connectors, sensor windows or venting holes.
How it feels in daily use
On the lab bench, a strip of PI Film bends without creasing, then snaps back to its original shape with a tidy, self-assured motion. When laminated into a flex cable, it gives the assembly a robust backbone that still threads through narrow chassis rails.
Technicians appreciate that the film does not curl aggressively at the edges after thermal cycling, reducing rework. The slightly matte surface also takes printed alignment marks well, which simplifies visual checks during manual assembly.
Hyosung Chemical on the market
Hyosung Chem positions PI Film alongside films for lithium-ion battery separators and other specialty polymers as part of its advanced materials portfolio. Overall, Hyosung Chemical shares trade on the Korea Exchange under ISIN KR7298000001, giving domestic investors exposure to these industrial products.
