High Performance FilmFlexible super-hard-coat film
Features
- High transparency
- High pencil hardness (3H – 8H) and continuous foldability
- Good abrasion resistance
Daicel’s flexible super-hard-coat films are hard but flexible.
While ensuring a high level of hardness, they are durable enough to withstand repeated bending in both in-fold and out-fold directions. This is why they are widely used as a cover film for foldable devices.
