*): CTI value not given in UL file or not tested by UL

(**): Values apply to the raw material, no details in the UL file

Note: polyester films are usually listed at 105 °C (generic value) – class B for adhesive tapes results from the corresponding tests for adhesive tapes. All films can be exposed to higher temperatures for short periods (e.g. polyester up to approx. 200 °C for hours). The information about the insulation material class relates to long-term application as an insulating film in electrical engineering
