XF-541 THERMAL TRANSFER PRINTABLE POLYIMIDE LABEL STOCK
Description:
Polyonics XF-541 is a polyimide label material with a permanent
pressure sensitive acrylic adhesive and a high opacity,
matte tan topcoat specifically designed for thermal transfer
printing on polyimide labels.
Polyonics
XF-541 polyimide label material is designed for barcode or alphanumeric
identification of printed circuit boards, or related electronic
components. It is the ideal label to withstand mixed circuit board
processes, on either the top or bottom side of the board. It has
excellent resistance to harsh fluxes, cleaners, saponifiers, and
wave solder environments, and resists all commonly employed methods
of cleaning. XF 541 polyimide labels are one of several polyimide
label materials available.Click on POLYIMIDE
LABELS.
The
printed polyimide label resists smearing, even when the board and
label are directly removed from a reflow or wave solder environment.
The XF-541 matte topcoat resists solder balls. For a list of recommended
thermal transfer ribbons see Thermal
Ribbons for Polyimide Labels.
XF-541 polyimide label material can also be printed with dot matrix,
laser, and ink jet printing technologies. Please email Printing
on Polyimide Labels Help, for more information.
The
choice of thermal transfer printer can make a real difference as
well on the overall polyimide label performance. Our materials can
be used with most industrial thermal transfer printers, such as
Zebra, Intermec, Sato, Printronix, NEC, Datamax, and Brady label
printers, for harsh environment bar code label printing with a wide
variety of thermal transfer ribbons.
XF-541
polyimide labels are also suitable for use in ISO clean-room applications,
when used with a film liner instead of a paper liner. Contact Polyimide
Labels for Clean Rooms for further information.

Customer
experience, supported by our laboratory data clearly show that XF
541 polyimide label material can be stored for at least one year
in an environment below 80 degrees F and 60% RH . We are confident
that our product will perform well beyond this time frame. However,
it remains the responsibility of the user to assess the risk of
using such product. We encourage customers to develop functional
testing protocols that will qualify a product's fitness for use,
in their actual applications.
