Polyimide Bondply

Polyimide Bondply is made of polyimide film coated by modified stage-B acrylic adhesive on two sides with

protection release film or paper. Polyimide bondply is widely used in protection of FCPB and other fields.

Characters:

* Excellent dielectric performance, high bondability and good dimension stability

* Low fluidity and good processability.

*Supplied with different sizes and colors.
