High Temperature Polyimide Label For Printed Circuit Board Labeling

High-temperature Polyimide labels are made of 1mil or 2mil polyimide film as the carrier, coated with acrylic pressure-sensitive adhesive. The matte white thermal transfer coating ensures easy readability of various barcodes and other variable information. They can withstand short-term high temperatures up to 320°C and long-term temperatures up to 280°C.

These labels exhibit excellent thermal stability, moisture resistance, and good initial tack, making them suitable for various applications such as PCB tracking, barcode tracking, solder masking during wave soldering, surface protection and masking, SMT processing, and protection of lithium batteries or chip packaging.
