Technical Information

V Grade Polyimide Film (Higher Grade)

Product No.:MAF02

MAF0213/MAF0225/MAF0250/MAF0275

Q-MANTIC ® V Polyimide Film is produced by adopting “Biaxial Tension Process” with max. width 1080mm. Its all performance indexes are better than H polyimide, especially Shrinkage and Tensile Strength.

MAF02 is close to Kapton® Type VN. There is one more production process as horizontal stretch during the V grade polyimide film production while there is only vertical stretch in the production of H grade polyimide film. So V grade polyimide film has superior dimensional stability and lower coefficient of expansion. It is VTM-0 UL approved with excellent flame resistance and it is suitable for application in aerospace, flexible printed circuits, photovoltaic, new energy batteries.
