*): 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

CTI

= tracking resistance

0= >600V (only CMC 278xx, Formex)

1= >400V-600V (e.g. Polyester film, Hostaphan or Mylar, Teonex, Kapton FN)

2= >250V-400V 3= >175V-250V (e.g. Aptiv Peek, Nomex)

4= >100V-175V (e.g. Kapton HN)

HAI

 = High Arc Ignition; UL 746C
= number of electric arc ignitions required to ignite the insulation material

0= >120
1= 60-120
2= 30-60
3= 15-30
4= 0-15

HWI

= Hot Wire Ignition; UL 746C time until ignition in sec.

0= >120
1= 60-120
2= 30-60
3= 15-30
4= 7-15
5= 0-7
