The silicone rubber heating plate is mainly composed of nickel-chromium alloy heating wire and silicone rubber high-temperature insulating cloth. The silicone rubber heating plate can be made into various shapes and patterns according to the size of the workpiece. The silicone rubber heating plate is very thin, light weight and flexible. With this kind of heater, it can be in full close contact with the heated object, allowing heat to be transferred to any place needed, improving heat transfer during processing, accelerating heating and reducing power requirements. It has the characteristics of good waterproof performance, fast heating, uniform temperature, high thermal efficiency, good toughness, convenient use, safe life of up to ten years, and resistance to aging.

The silica gel electric heating element has stable quality, moisture-proof and chemical corrosion resistance. The temperature range can be -62～235℃, and the maximum power load that can be provided is 3.1W/c㎡. Because this product is very thin, the heat transfer effect is good, and it is practical. The heating element is very close to the workpiece. There are currently two circuit forms, one is the etching circuit method, the maximum width can be 360mm, the length is not limited; the heating element is a sheet-shaped electric heating element structure, which provides a more uniform thermal field than a wire-shaped electric heating element, and the heating time period is And the response time is fast, compared with the filament heating element, the power load is low, and the service life is longer. The other is the arrangement of round wire heating elements. It is widely used in industrial, medical, laboratory, food and aviation fields.
Features:
1. Various shapes and sizes can be customized according to customer requirements (such as round, oval, cone...).
2. The insulating layer of the silicone rubber heating plate is composed of silicone rubber and glass fiber cloth, which has high insulation performance, and the breakdown voltage can reach 20-50KV, so it can be used with confidence.
3. The installation of the silicone rubber heating plate is extremely convenient. It can be installed through room temperature vulcanized rubber, vulcanized, or installed in holes according to customer requirements, or installed in the form of bundles.
4. Heating element: Winding the heating wire of nickel alloy on the glass fiber wire, the heating power can reach 2.1W/c㎡, and the heating is more uniform.
5. Moisture-proof and chemical-proof silicone rubber material provides longer heater life.
illustrate:
1. When using this type of electric heating device, it must be noted that its continuous working temperature should be less than 240℃, and the instantaneous temperature should not exceed 300℃.
2. The silicone electric heating device can work and press, that is, use the auxiliary pressure plate to make it close to the heated surface. The heat conduction is good, and the current density can reach 3W/c㎡ when the temperature in the working area does not exceed 240℃.
3. The allowable working temperature is less than 150°C under the condition of stick-on installation.
4. In case of dry burning in the air, the power density should be less than 1 W/c㎡ due to the temperature resistance of the material; in non-continuous working conditions, the power density can reach 1.4 W/c㎡.
5. The working voltage selection is based on the principle of high power-high voltage, low power-low voltage, and special needs can be listed.
