The electric heater is a new type of electric heating product, which is a soft and bendable film-like electric heating device. It is made by evenly distributing the metal heating element in the shape of a moor and wire in the glass fiber cloth coated with high temperature resistant silicone rubber and pressing it at high temperature. Its body is thin, usually 0.8~1.5mm thick, and light in weight.

Electric heating film composition
Electric heating film is a new type of electric heating product. Compared with traditional metal electric heating products, it can be more closely attached to the surface of the heated object during heating, so it is very popular among customers.
The electric heating plate is a kind of flexible and flexible film-like electric heating device. It is made by evenly distributing the metal heating element in the form of berths and filaments in the glass fiber cloth coated with high temperature resistant silicone rubber, and is molded at high temperature. Its body is thin, usually 0.8~1.5MM thick, light weight, general, 1.3~1.9 kg per square meter. It has the characteristics of rapid heat generation and rapid temperature rise when electrified. It has the characteristics of large heating surface, uniform heating, weather resistance, corrosion resistance, environmental protection, flame retardant, easy installation, long life, and high insulation strength. It is unique among many electric heating devices.
The use of silica gel electric heating film
Electric heating films have been widely used in various industries such as providing thermal environment for outdoor communication equipment, outdoor insulation and antifreeze, chemical equipment heating, pipeline antifreeze, outdoor equipment backup battery insulation, medical treatment and other industries.
To put it more popularly, because of its softness and flexibility, the electric heating sheet is often used to cover the surface of some curved objects to achieve heating, such as oil drums, pipes, and experimental equipment.
Instructions for use of electric heating film
1. When using this type of electric heating device, it must be noted that its continuous operating temperature should be less than 240℃, and the instantaneous temperature should not exceed 300℃.
2. Kunzhong silicone rubber electric heating sheet can work and press, that is, use the auxiliary pressure plate to make it close to the heated surface. At this time, the heat conduction is good, and the power density can reach 3W/cm2 when the temperature of the working area does not exceed 240℃.
3. The allowable working temperature is less than 150℃ under the condition of sticking installation.
4. In the case of dry burning in the air, the power density should be less than 1 W/cm2 due to the temperature resistance of the material; in non-continuous working conditions, the power density can reach 1.4 W/cm2.
5. The working voltage selection is based on the principle of high power-high voltage and low power-low voltage, and special needs can be listed.
