Product Info.

1. Introduction:

      What we called the heating element is generally used to convert the electricity/electric energy into heat. With the power being connected, the current will pass through the inside element, in the meanwhile, it will encounter the resistance, then will lead to the heating of the element equipment, thus achieve the final heating purpose. Different from the Peltier Effect, the current flow of this process is totally independent to control it current flow direction.

2. Structure:

      The resistive heater can be made of the conductive PTC rubber material. Inside of it, the resistivity increases exponentially with the increase of temperature. This heater will produce high power when cold and quickly heated to a constant temperature. As the resistivity increases exponentially, the heater cannot be heated to a higher temperature than this. At this temperature, rubber acts as an insulator. The temperature can be selected in the rubber production process. The typical temperature is from 0~80℃.


       It is an intelligent self-regulating heater and self - limiting heater. 

  • Self - regulation means that each point of the heater is independent of the constant temperature without regulating electronics. 

  • Self - limiting means that the heater cannot exceed a certain temperature at any point and does not require excessive heat protection.
