Master Rolls
Full-width rolls for precision coating, lamination and further converting.
Specialty Films / Electrical Insulation
An enhanced-performance polyimide film for FCCL, precision tape backing and dimensionally critical converting.

Functional Uses
ATR-PI-EP supports FCCL base-film, precision tape-backing, dimensionally critical electronics and precision converted-part applications.

Converting Quality
ATR-PI-EP combines improved dimensional stability, higher modulus, mechanical uniformity, thickness uniformity and flatness to support registration and converting control.
Improved dimensional behavior supports registration, layer alignment and repeatable converting in demanding processes.
Higher modulus and more uniform mechanical performance support controlled web handling through coating, lamination and precision converting.
Improved thickness uniformity and flatness help maintain consistent contact, alignment and downstream process control.
Available Forms
ATR-PI-EP is available in master rolls, slit rolls and die-cut parts. Width, length, core size, winding and converted format are confirmed for the intended process.

Full-width rolls for precision coating, lamination and further converting.
Customer-specified widths prepared for controlled downstream processing.
Converted insulation parts produced to the agreed drawing and application requirements.
