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 ¨C269¡æ (¨C 452¨H) and as high as 400¡ãC (752¨H).

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
