High adhesion waterproof polyimide tape for lithium battery

Product Description

Polyimide H film is synthesized by polymerizing PMDA and ODA in strong polar solvents through

the process of film forming and imine treatment at high temperature, which possesses excellent

physical, chemical, and electrical properties; it is also radiation resistant, solvent resistant,

low & high temperature resistant, It can be applied successfully in a wide range of temperature

as low as -452F (-269c) and as high as +500F (+260c). Thanks to its unique excellent

properties, it is the ideal candidate in many applications.

Application

It can be used in a variety of electrical and electronic insulation applications: such as wire and

cable tapes formed coil insulation, substrates for flexible printed circuits(FPC), motor slot liners,

magnet wire insulation, transformer and capacitor insulation, magnetic and

pressure-sensitive tapes, and tubing, etc.

Note: We can provide black, white and other colours of the polyimide film according to

the customer's request.

Technical Data

Appearance and Colour

Appearance

Transparent or semi-transparent with a smooth surface, free of wrinkle, crack,

particle, bubble, needle cavity, bubbles or foreign impurities/defects

Colour

Depending on the thickness of film, the color may change from transparent/semi

-transparent golden color to dark brown color, as the film thickness is increased
