  • DuPont Teijin Films™ (DTF) has been a leading high quality supplier of polyester PET and PEN films for more than fifty-five years. For many of those years the heat stabilized Melinex® ST™ polyester range has been available. These products have provided enhanced dimensional stability for higher temperature applications and processes. The figure below shows the shrinkage response of a typical product in that range versus standard Melinex® and Mylar® films. 

     

    In 2006, DTF commissioned a state of the art heat stabilizing asset in the USA which can thermally stabilize PET film from 2mil to 14mil (50 – 350 microns), with a max web width of 76” (1930mm). Proprietary technology is employed to provide best in class dimensional stability, consistency of shrinkage, web flatness and surface quality. Further parameters such as shrinkage and flatness can be customized to match your application.

    Today, DTF continues to run a wide variety of film types sold into many diverse applications, including: printed electronics, display, photovoltaics, MTS and medical diagnostics.

    Scott Gordon, Marketing Manager for the heat stabilized films, says “Our Melinex® STTM range is a differentiated PET film option that is required for many new applications, including the high growth Flexible Electronics segment. The improved dimensional stability can be used in higher temp processes, for holding registration in multi-pass printing or in applications where peak temperatures would provide an unacceptable response from our standard films. All of these benefits come with no compromise to the excellent performance of polyester, for example mechanical strength, chemical resistance, and ink adhesion”.

    DuPont Teijin Films continues to develop new products that include this dimensional stability.  For example, the new UV Stable Melinex® TCHUV films are also offered at heat stabilized Melinex® STCHUV films.

    The flexibility of the current manufacturing process allows any standard product to be further stabilized within the thickness and width criteria previously stated. Film options could include variations in polymer for color, optics and flammability plus surface coatings for a wide array of effects.

    Since 1992, Tekra has represented DuPont Teijin Films™ as a leading converter, coater, and distributor of DTF manufactured innovative ST™ Melinex® films. Tekra is unique in that we are both an authorized distributor and manufacturer of custom hardcoated PET films.
