Low Cost, Polyimide (Kapton^®) SUBSTITUTE
for Circuit Board Bar Code Labels

Westmoreland, NH -- POLYONICS, Inc., announced a low cost, thermal transfer printable modified polyimide (sometimes known as Kapton^®) label material, XF 558, which withstands circuit board manufacturing process temperatures of up to 500° F. This modified polyimide allows the user cost savings of up to 50%, over Kapton^® based label materials. Labels printed with the proper thermal transfer ribbon can withstand the harshest solvents, cleaners, fluxes, and saponifiers, even without overlamination.

"This product uses the same outstanding Thermogard^® coating technology used in our widely acclaimed Kapton^® product, XF 557," said Dr. James R. Williams, Polyonics' Director of Marketing and Sales. "In addition, it offers advantages over cast acrylate films, a so-called Kapton^® substitute, " he added. XF 558 delivers consistent print quality and proven chemical resistance when printed with the proper thermal transfer ribbons. Higher converting yields are realized than with cast acrylates, due to higher tear and tensile strengths, which means higher profits for converters. However, Williams noted that each user must thoroughly test this material in his or her actual process environment, since it may not be suitable in all cases.

Polyonics is widely recognized as the premier manufacturer of labelling materials for harsh environment/industrial bar code label applications. Polyonics markets and distributes its products through commercial label printers and converters worldwide.
