Silicone rubber heating plates are thin, lightweight and flexible. With this heater, it can be in full contact with the object being heated, allowing heat to be transferred to any desired location, improving heat transfer during processing, accelerating temperature rise and reducing power requirements. It has good waterproof performance, fast heating, uniform temperature, high thermal efficiency and good toughness. The silicone rubber heating plate has stable quality, anti-humidity and chemical corrosion resistance. The temperature range can be from -62 to 235 °C, and the maximum power load can be up to 3.1 W/cm2. Because the product is very thin, the heat transfer effect is good. The heating element is very close to the workpiece. At present, there are two circuit forms, one is an etched circuit method, the maximum width can be 360mm, and the length is not limited; the heating element is a chip-shaped electric heating element structure, which provides a more uniform thermal field than the wire-shaped electric heating element, and the heating period is It has a fast response time and a low power load and a longer service life than a filament-shaped electric heating element.
