6. Can I immerse these heaters in water or other liquids?

Generally the answer is no. The materials used in polyimide insulated Thermofoil heaters are waterproof, but edges are not sufficiently sealed for immersion. Custom designs (including all PTFE heaters) can include increased border areas and sealed leadwire connections that make these heaters immersible in water. Silicone rubber insulated heaters require RTV cement or similar materials along all exposed edges and leadwire attachment areas for immersion in water.
