6050J Polyimide Film

Application: Used for various interturn insulation of F class motor, wire wrapping insulation,  transformer insulation and meter insulation.

Features: The substrate is a polyimide film, coated with F grade adhesive, after baking, cut it into electrician thermosetting pressure-sensitive adhesive tape with a smooth surface and uniform layer, no gummosis, when unwinding, no glue transferring phenomenon, tape edge will be neat without damage, this product has good adhesion properties, insulating properties and heat resistance. Heat-resistant class is F.
