Heat Stabilized Polyester Films (ST Films)

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.

Benefits of Melinex® Heat Stabilized Polyester Films

There are a variety of perks when it comes to heat stabilized polyester films, and those are:

  • Thermally stabilized at 150°C for 30 minutes (MD/TD shrinkage at <1%); ensures proper registration and 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 allow thinner films to retain rigidity when inserted into reading devices
  • Polyester films are inert and plasticizer free, meaning no surface migration over time
  • Engineered surfaces with primer systems to remedy difficult adhesion challenges
