Polyimide film (tape) 6051
Standard No.: JB/T 2726-1996
Applicable Range: The polyimide film is manufactured with the raw materials of pyromellitic dianhydride and 4,4---diaminodiphenyl ether synthetic resin, and adopted with doctor-blading process. It can resist high temperature and radiation as well as possess excellent dielectric performance and physical performance. It is applicable to motor Grade H, electric appliance insulation, and the electric insulating materials for other purposes.
I. Technological requirement:
1. Appearance: Film surface is smooth, bright and clean. It shall have no defects, such as folding, tearing, particulate, air bubble, pinhole and any external impurity. Its edges shall be orderly and have no breakage. And the film is provided in rolls.
2. Dimension1) Thickness and allowable deviation: see the recommended thickness in Table One. The products with other thickness can be supplied according to the requirements of customer.
