Comments
Polyimide/WA
Polyimide film with
thermosetting acrylic adhesive
(not UL recognized)
-200 to 150°C
-328 to 302°F
560 mm × 1825 mm
22" × 72"
230 Ω/cm²
1500 Ω/in²
Similar to Polyimide/FEP except lower cost,
higher resistance densities, and lower tempera-
ture range. WA is preferred over FEP for most
custom designs under 150°C.
Polyimide/ULA
Polyimide film with UL
recognized thermosetting
acrylic adhesive
-200 to 150°C
-328 to 302°F
560 mm × 1825 mm
22" × 72"
230 Ω/cm²
1500 Ω/in²
Similar to Polyimide/WA except UL recognized
(UL94V-0).
All-Polyimide (AP)
Polyimide film with
polyimide adhesive
-200 to 260°C
-328 to 500°F
560 mm × 1145 mm
22" × 45"
230 Ω/cm²
1500 Ω/in²
Higher temperatures and watt densities
than industry standard flexible Polyimide
construction.
PTFE -200 to 260°C
-328 to 500°F
254 mm × 1016 mm
10" × 40"
70 Ω/cm²
450 Ω/in²
Fully sealed construction suitable for immersion
in acids, bases, and other corrosive chemicals.
Polyester
(with thermosetting adhesive)
-40 to 105°C
-40 to 221°F
560 mm × 1825 mm
22" × 72"
217 Ω/cm²
1400 Ω/in²
Low cost material for economic fabrication of
large heaters.
