Hey guys, i am here to try pick some brains. I am en electronic engineer who is currently playing with some projects at home. I am creating a monstrous e-cigarette prototype. I am not using the conventional nichrome wire and wick method, but rather just dropping it onto a hot plate for instant clouds. Anyway the burning question is about insulators, i will have a handheld unit that will get pretty hot around the heater. I was hoping to put a heat buffer between my heaters enclosure and the outer enclosure. Some thermally insulating material that is also inert and safe for someone to be inhaling hot air over. I had thought about thermoplastic and pocket of air as an insulator. Mica doesn't seem flexible enough. What do you guys think? Any tips or suggestions are greatly appreciated! Genuinely!
