China Widely Used Polyimide Pi Film with High Temperature Resistant

Widely Used Polyimide PI Film With High Temperature Resistant

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.
