Heat Stabilized PET

Melinex® ST polyester films are recognized as the premier line of heat stabilized polyester films for printed electronics, flexible circuitry, optical display, membrane switch and related industries.  

Some performance benefits for Melinex® ST polyester films include:

  • Thermally stabilized @ 150°C for 30 minutes (MD/TD shrinkage @ <1%); ensures proper registration & performance of silver conductive inks
  • High tensile strength permits higher film processing speeds
  • Superior flatness for better web handling and higher yields
  • High stiffness and caliper control allows thinner films to retain rigidity when inserted into reading devices
  • Polyester films are inert and plasticizer free; no surface migration over time
  • Engineered surfaces with primer systems to remedy difficult adhesion challenges
