Product Desciption

Insulating material polyimide film for speakers

1. Polyimide Film
Polyimide film is a special plastic film, has excellent mechanical properties, dielectric properties, no melt at

-195 ° C - 280 ° C under the conditions of long-term use. Because of its unique high performance main as

the base dielectrics for Flexible Printed Circuits (FPC), Tape Automated Bonding (TAB), Pressure Sensitive

Tape (PST), Insulation for Electric Motor (Insulation) etc., it is widely used in sophisticated product of

military affairs, satellite navigation, digital product, H grade and F grade electric motors, computer and

mobile phone etc.
