8. When would I specify aluminum foil backing for a heater?

Foil helps to spread heat between heater strands, improves adhesion of PS, and makes polyimide less springy for better conformance to curves. It increases the temperature and watt density ratings of polyimide heaters with PSA. For silicone rubber heaters, foil with acrylic PSA is less expensive than #12 PSA applied directly to the rubber.
