PI Film
Polyimide film for high-temperature insulation, flexible circuits, battery insulation, and precision electronics converting where thermal stability and dielectric performance are required.
Material family
Polyimide (PI) functional film
Typical product form
Roll film, slit width, sheets, and converted die-cut pieces
Primary performance direction
High-temperature insulation, dimensional stability, and dielectric support
Overview
ALS Tape supplies polyimide (PI) film as a high-performance functional film for applications where temperature resistance, electrical insulation, and dimensional stability must be maintained through converting and final assembly. PI film is commonly specified for flexible printed circuit structures, insulation wraps, slot liners, battery insulation pieces, masking support layers, and thin dielectric barriers in electronics and advanced manufacturing programs. ALS can support custom slit widths, sheet supply, laminated constructions, and precision die-cut converted parts so PI film is delivered in a production-ready format.
