The Advantages of MCH Ceramic Heating Element for E-cigarettes

The traditional electronic cigarette heating element is a metal heating wire. Although the heating effect can meet the needs, it has many shortcomings in other aspects. Nowadays, most electronic cigarette heating elements gradually no longer use traditional metal heating wires, but choose ceramic heating elements.
Metal Ceramics Heater (MCH) Heater for E-cig

Mainly because ceramic heating elements have the following advantages:

  • The heating speed of ceramic heating element is faster than that of traditional heating wire;
  • The heating temperature of ceramic heating element is higher than that of traditional heating wire;
  • The ceramic heating element does not leave any stains or dirt when used, which is especially beneficial to electronic cigarette products.

In the e-cigarette industry, heating elements are widely used, and ceramic heating elements are considered a breakthrough for the e-cigarette industry. Many e-cigarette customers give up using the traditional electric heating elements. Some e-cigarette heating elements could be viewed directly, so for dirty heating elements, it will affect the customer’s use. Ceramic heating elements have advantages in this regard, because the surface of the ceramic heating element is white. The key point is that it will not get dirty easily when used. From the appearance, it has a high-end and classy feeling.


About (Metal Ceramics Heater) MCH:

1. MCH is the abbreviation of Metal Ceramics Heater, which means metal ceramic heating element.

MCH refers to printing high melting point metal heating resistor paste such as metal tungsten or molybdenum manganese on a 92 to 96% alumina cast ceramic green body according to the requirements of the heating circuit design, and then laminating it by hot pressing, and then heating it at about 1650℃ The ceramic heating element, which is made by sintering ceramics and metal under the protection of a reducing atmosphere, has the advantages of corrosion resistance, high temperature resistance, long life, high efficiency and energy saving, uniform temperature, good thermal conductivity, fast thermal compensation, and does not contain lead or cadmium. , mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers and other harmful substances, and complies with EU RoHS and other environmental protection requirements and CE certification.


2. Main Raw Materials:
