A stretched silicone rubber heater produces heat due to the Joule heating effect. When an electric current flows through a conductor, such as a stretched silicone rubber heater, it encounters resistance. This resistance causes the electrical energy to be converted into heat energy, which is then dissipated as heat.
In the case of a stretched silicone rubber heater, the silicone rubber material is a good electrical insulator, which means that it resists the flow of electricity. However, when the silicone rubber material is stretched, it becomes less resistive and allows more electrical current to flow through it. This increased current flow results in a higher rate of energy conversion from electrical to thermal energy, which produces heat.
The amount of heat produced by a stretched silicone rubber heater is directly proportional to the electrical current flowing through it and the amount of resistance encountered by the material. By controlling these parameters, it is possible to adjust the amount of heat generated by the heater and use it for various applications, such as in heating pads, warming blankets, and other heating devices.
