VN Polyimide Film
Description:
VN Polyimide Film (equivalent to Kapton® VN Film, APICAL® Type NP, LIREN® VN) is a low-shrinkage film, synthesized by polymerizing an aromatic dianhydride and an aromatic diamine. It has the excellent balance of electrical, thermal, mechanical, physical, and chemical properties over a wide range of temperatures as low as –269℃ (– 452℉) and as high as 400°C (752℉).
VN Polyimide Film not only has all of the properties of Type HN, but also has superior low shrinkage and dimensional stability. It has the highest UL-94 flammability rating: V-0. The UL File Number is E31879.
Characteristics
• Superior low shrinkage
• Excellent dimensional stability
• High dielectric strength
• Chemical resistance
• Flame resistance UL V-0
• UL approved qualified film
• Temp resistance from -269°C to over 400°C (-452°F to over 752°F)
Application:
VN Polyimide Film can be used in flexible printed circuit board (FPC), voice coil and other special department which requires superior dimensional stability, good peel strength, and so on.
