\n- Whitening or cracking after repeated bending<\/li>\n
- Insufficient bending lifetime, leading to performance degradation after frequent folding<\/li>\n
- Optical surface degradation and increased yellowing<\/li>\n
- Inability to support ultra-small bending radii (R < 1 mm)<\/li>\n<\/ul>\n<\/div>
The market therefore urgently requires a transparent high-performance film that can bend, roll, and endure over time.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
