Functional film
EPU(Elastic poly Urethane) Flexible Film?
- A material that has excellent transmittance (93%, higher than glass), high elasticity (excellent self-restoration), and thickness stability (clear image quality without orange peel) and is intended for application in various fields, including displays -> used in industrial, construction, and automotive interior/exterior materials and achieved high market growth rates.
Necessity?
- Recently, the development of new and elastic materials (epu) has become necessary due to changes in 3D structures and folding displays
Key Features
Excellent 93% transmittance
- Higher transmittance than TPU (Thermoplastic polyurethane) film
Excellent 3D curve
- Superior curvature than TPU (Thermoplastic polyurethane) film
Excellent self-healing ability
- Overcomes scratches and pressure issues better than TPU (Thermoplastic polyurethane) film
Thickness Stability
- Wider thickness productivity than TPU (Thermoplastic polyurethane) film (20um~300um)
