General Polyimide Film (TH)
TH is traditional polyimide film for general purposes. Customers are satisfied its stable quality. Lower stiffness、excellent heat resistance and electrical insulation properties meet customer’s requirements from the different industries. |
|
|
|
| |
|
- Higher elongation
- Lower stiffness
- Balanced MD/TD properties
