E-8632 is a 2 mil (0.064 mm) matte white polyimide thermal-transfer label stock for functional labelling of highly specified electronic goods. With appropriate thermal-transfer ribbons it delivers high-quality, high-resolution print for topside printed-circuit-board manufacture and traceability. The polyimide construction is dimensionally stable at high temperature and chemically resistant, and prints resist smearing when the board and label are removed directly from a reflow or wave-solder environment. Its removable adhesive allows the label to be lifted cleanly without residue for rework and re-identification.
