Electrical Insulation Pi Film with High-Quality Surface Treatment for Transformer

Product Description

Product Description

Polyimide film is made of pyromellitic dianhydride (PMDA) and diaminodiphenyl ether (ODA) in a highly polar solvent, which is polycondensed and cast to form a film and then imidized. The film has excellent high temperature resistance, electrical insulation, solvent resistance, and atomic radiation resistance, and can be used for a long time in the range of - 269 to +260°C. It is widely used in the wrapping of electromagnetic wires and cables, slot insulation, interphase insulation and gasketing of motors and appliances, and can be used as the base film of polyimide tape and flexible printed circuit boards.
Product thickness (mm): 0.125, 0.025, 0.05, 0.075, 0.10, 0.125.
Width (mm): 500, 520, 1000, can be cut into various widths according to user needs.

(1) Appearance
It is amber translucent, the surface is extremely smooth, there are no obvious impurities, pinholes, bubbles, and the edges are neat. This appearance quality ensures reliability in high-precision application scenarios, such as in electronic display manufacturing, and the display effect will not be affected by defects on the film surface.
(2) Various thickness specifications
Provides a variety of thickness options from 25μm to 125μm (including 25μm, 40μm, 50μm, 75μm, 100μm, 125μm), which can meet the specific needs of PI film thickness in different industries and different products. Whether it's flexible electronic circuits that require less thickness, or industrial insulation applications that require thicker PI films for strength, we have the right product.
