Polyimide
Film is produced by cast method, which has high temperature resistance,
resistance to
|
|
|
|
radiation
and excellent dielectric properties. It is applicable to electrical
insulating of the class H electric
|
|
|
motor
and other electrical equipments, and other use electrical insulating
materials.
