Mineral insulation heater is a high-performance heater, which adopts pure MgO, better heat-conducting property than traditional mica and ceramic, as insulation material. A thin and dense layer of nanometer MgO is filled between electric heating wire and metal sheath so that the heat energy of the heating wire will be transmitted very quickly to the heated object, bringing down the heating wire’s temperature and enhancing the heater’s working life greatly. On the other hand, the working temperature can be up to 760℃℃. Hence, the mineral insulation heater is better to meet modern plastic production craft.

      6. Heating evenly and stably, having a longer life time.
