Glass Fiber Etched Silicone Rubber Heater

Glass Fiber Etched Silicone Rubber Heating Element

According to the CAD drawing output film, through the printing and etching process to the required film. As it is a sheet product (standard thickness is 1.5mm), it has good flexibility and can fully contact with the heated object. Because of its flexibility, it is easier to get close to the heated object, and the shape can be designed to be heated according to the requirements, so that the heat can be transferred to any required place. The general plane heater is mainly composed of carbon, and etched silicon heater is composed of arranged nickel alloy resistance wires, so it can be used safely. The surface heater can be made according to the requirements. The product is widely used in medical and health care, instruments and mechanical equipment and other tubular, surface like antifreeze, heat preservation and heating.

According to different naming habits, we also call the silicone rubber heating pad as silicone rubber heating sheet, silicone rubber heating plate, silicone rubber electric heating sheet, silicone rubber electric heating film, etc. with or without temperature control.

Characteristics of Glass Fiber Etched Silicone Rubber Heaters:

Etched foil elements can provide special advantages for manufacturers looking for thinner flexible heaters in applications where size and weight are serious issues. They can be used for short-term and long-term production because these components can achieve higher power density and rapid heating capabilities.

Although the etched foil needs a wider width to provide the same wattage and resistance as the winding components, these components can be placed closer together without contact and short-circuiting. Therefore, the etched foil can be in a tighter space on the substrate. Finally, manufacturers can obtain more precise temperature control with complex heat distribution characteristics.

Alloys for heating elements

Some metal alloys have both thermal conductivity and electrical resistivity, so they are suitable for heating elements. Alloys are composed of base metals and other trace metal elements, which are added in a specific process to change the mechanical, structural, electrical, thermal and conductive properties of the base metal. The inherent properties of the alloy may be improved, such as higher corrosion resistance or conductivity, or reduced impurities. Commonly used alloys in heating elements include stainless steel, nickel-chromium, copper-nickel or Inconel 600.

304 stainless steel

Stainless steel 304 is a metal alloy composed of chromium and nickel because it also combines with carbon. It can be formed using a variety of techniques including hydroforming. The main advantages of stainless steel are excellent heat transfer ability, corrosion resistance and ease of manufacturing. Its heat capacity is 20°C and the maximum mechanical temperature is 420°C.

Nichrome

Nickel chromium contains a certain percentage of nickel and chromium. The addition of chromium increases electrical resistance and corrosion resistance to high temperatures. Due to its ductility and strength, the alloy is suitable for winding components. The maximum working temperature of this alloy is 1100°C, and the heat capacity is about 20°C.

Copper nickel

Copper nickel has incredible corrosion resistance and electrical resistance. This alloy is often sought after due to its good workability. Although it is more suitable for 400°C heating elements, its maximum mechanical temperature is 600°C. It also provides a heat capacity of 20°C.

Inconel 600

Inconel 600 alloy is best suited for applications requiring high corrosion and electrical resistance, and it is also non-magnetic, which makes the alloy ideal for flexible heater elements used with products that are susceptible to magnetism, in outdoor and humid environments. It contains a combination of nickel, chromium and some iron. It also has high chemical resistance. The heat capacity of this alloy is 20°C and the mechanical temperature is 1100°C.

Use the correct heating element for your application

The best way to select the heating element for the application is to determine the required power density, the required heat transfer and preheating, the working environment and the required heater size. If the manufacturer needs a large, robust heater with a small bend radius, and the entire process requires multiple watt densities, then a wirewound heater can do the job. For applications that require fast heating and a thin flexible heater with good overall heat transfer capability, etched foil elements can be used.

Jaye heater technology, we design and manufacture flexible heaters for manufacturers in various industries. We can customize the heater using the appropriate materials and heating elements required by the application.
