content: I would like a cartridge heater which could go up to 400 degrees C. Ebay is littered with cheap cartridge heaters from hong-kong but none of them provide any kind of maximum temperature specification.http://www.ebay.com/sch/Business-Industrial-/12576/i.html?_from=R40&_nkw=cartridge+heater&_pgn=2&_skc=50&rt=ncWill these work?I would like a solution that does not cost 20+ dollars a heater mainly.

content: Those cartridge heaters are not ideal for your application; in all honesty, you would be better to buy a hot-gun or a paint stripper !

content: well regardless of my folly I still want to know what those things are rated for, just in caseI just wanted to make a modular lab compressor system (pickup tool, venturi cooling pipe (EVEN THOUGH I HAVE DUSTOFF) (http://en.wikipedia.org/wiki/Vortex_tube) (also doubles as smoke remover), solder pickup tool, hot air gun and solder paste dispenser.I know I can buy all this stuff cheap but it is more for fun then anything. I already own a proper hot air gun... it's just fun to misuse things you know? Plus customization, like foot pedal solder sucker or blower control is kind of neat.

content: The ones meant for plastic extrusion are normally rated to about 350C, as most extruders will operate at around 150-300C depending on the particular machine. The leads however are often only rated to 200C, as they are going to be outside the heater blocks and this is a cheaper insulation to make in a flexible form. Somw will operate to 600C, but then you will find the leads are made from ceramic beads threaded on the wires.
