Comments<br />
*Resistance density varies with the size of the heater (higher density possible with smaller heaters).<br />
Similar to Polyimide/FEP except lower cost,<br />
higher resistance densities, and lower temperature<br />
range. WA is preferred over FEP for most<br />
custom designs under 150°C.<br />
Similar to Polyimide/WA except UL recognized<br />
(UL94V-0).<br />
Higher temperatures and watt densities<br />
than industry standard flexible Polyimide<br />
construction.<br />
Fully sealed construction suitable for immersion<br />
in acids, bases, and other corrosive chemicals.<br />
Low cost material for economic fabrication of<br />
large heaters.<br />
