Cartridge heaters are reasonably priced, robust and easy to install. As a rule they consist of a cylindrical stainless steel tube and thus provide a high corrosion prevention. There is a heating wire inside which is wound onto a ceramic core. The number of coils varies depending on the power. In order to avoid a short-circuit, the cartridge heater is filled with magnesium oxide and compressed afterwards. Highly compacted they reach a surface watt density of up to 50 W/cm² and withstand highest stress.

square cartridge heaters are used where much power has to be installed near the surface of a tool, e.g. in cutting knives, sealing stations or hot plates. The cartridge heaters can easily be pressed into a rectangular groove. Apart from the advantageous heat transfer over ¾ of the sheath, it is not necessary to cement or cast in the heater which is imperative for round cartridge heaters. Unlike tubular heaters which are also available in square sections (see chapter Flexible Heating Pipes), the square cartridge heaters have the termination on one side and can be loaded with 16W/cm² (2.5W/in²) due to their special inside construction.

Silicone heaters are resistant to permanent temperatures up to 200°C, with self-adhesive foil 180°C should not be exceeded. Higher temperatures of 230°C is possible for a short time without destroying the heater. The temperature that will be reached within the application, generally is not easy to predict, as there are many influencing factors. In addition to the power, resp. surface load, this also includes mass and type of the material to be heated (thermal conductivity, surface quality, etc.) installation / assembly situation (bonded, vulcanised, clamped, etc.), ambient temperature, air movement and, of course, the control technology used. Application examples for silicone heater mats include: canteen kitchen technology / catering, anti-fog and anti-freeze applications, tool or plate heating in machines, 3D printers, laboratory equipment, composite materials repair, joint curing and much more.
