Kapton® PST

Kapton® PST crystalline polyimide film designed for the pressure sensitive tape industry

Kapton® PST is a tough film that exhibits an excellent balance of physical, chemical and electrical properties over a wide temperature range, particularly at unusually high temperatures.

DuPont™ Kapton® PST grade polyimide film is a crystalline film designed for the pressure sensitive tape industry with improved film attributes for PST coaters. Film properties that aid in coater performance include superior point thickness and gauge control across the web, improved roll formation, and extended roll lengths. The film is available in 50, 100, 200, 300 and 500 gauges.

Features include:

  • Superior tensile strength
  • Good elongation
  • Minimal variation between MD and TD properties
  • Superior dielectric
  • UL listing
  • Long length splice-free rolls
  • Batch-to-batch uniformity
