Polyimide Film 6051 Film polyester

Specifications

Polyimide Film 6051

Standard No: JB/T2726-1996

Application scope: The polyimide film is produced by adopting ”Doctor-Blading Process”.It processes heat-resistant, radiation resistant and excellent dielectric performance and applies to motor grade H electrical insulation as well as the electric engineering insulating materials for other usage.

Technical specifications.
