How Silicone Rubber Heaters Work

Silicone Rubber Heaters generate heat from electrical resistance elements within the heater sheet. When supplied with power as per design specifications, the heating elements transfer thermal energy through a silicone structure to the surface of the workpiece in contact with it.

The efficiency of heat transfer depends on wattage, contact surface area, tightness of fit between the heater and the workpiece, and characteristics of the material of the workpiece.

Installation should choose an appropriate mounting method that suits both the heater structure and the workpiece surface to ensure good heat transfer and reduce risks from abnormal high temperature accumulation.

Flexible Heater Design

The standout feature of silicone sheet heaters is their flexible design, which allows for easy installation on workpieces with curved shapes or specific mounting areas compared to some rigid heater types.

Bending or curving must be within the design specifications and should not involve sharp folds or repeated bending that could damage heating element structures and electrical insulation.

If the heater needs to be installed on a surface with a large curve, please provide details of the radius and size of the installation area for the manufacturer to check suitability before ordering.

Installation on Workpiece Surface

The Silicon Heater can be designed for installation on workpiece surfaces. The appropriate attachment method must be selected based on environmental conditions and operating temperature.

The attachment may consider clamping, mechanical fixing, or other forms as designed and approved by the manufacturer. It should not be assumed that all heaters come with a pre-applied adhesive layer.

Installation on sharp surfaces, contaminated surfaces, or in conditions that could damage the silicone sheet should be avoided.

Electrical Power Design and Watt Density

The selection of heater power should consider the mass of the workpiece, initial temperature, target temperature, heating time required, and system heat loss.

In addition to total electrical power, watt density (Watt Density) per surface area must be considered appropriately for thermal conductivity capability. Selecting too high a Watt Density may cause hot spots and reduce heater lifespan.

The appropriate values of power and Watt Density must be confirmed by the manufacturer based on actual usage conditions.

Temperature Control

The use of silicon sheet heaters should have an appropriate temperature control system, such as Temperature Controller together with Temperature Sensor to control surface or workpiece temperature.

For tasks that pose a risk of overheating, consider over-temperature cut-off devices separate from the normal temperature control circuit according to system risk levels.

Applications

• Heating surfaces of machine parts
• Heating workpieces with curved shapes
• Heating pipes or containers designed for support
• Heating metal sheets or components
• Maintaining temperature of equipment and machines
• Spot heating in production processes
• Designing heating systems for specific machinery
• Replacing old heater sheets according to specifications

The above examples are applications that require appropriate design selection, not implying that all sizes of heaters can be used in every environment.

Silicon Heater Selection Guidelines

• Check the size and surface characteristics of the heating area needed
• Determine the operating temperature and target temperature of the workpiece
• Specify the voltage according to the existing system
• Calculate power requirements based on the thermal load of the system
• Verify the electrical density over the heater area
• Check the required curvature for installation
• Determine an appropriate mounting method
• Select wire position and terminals safely
• Consider temperature control systems and overheating protection systems
• Prepare drawings or samples for the manufacturer to review

Usage Safety Precautions (Safety Precautions)

• Use the electrical voltage as specified by the manufacturer
• Avoid operating above the certified maximum temperature for that heater model
• Avoid folding the heater at sharp angles or bending beyond material limitations
• Avoid drilling, cutting, or modifying the heater sheet after production
• Install to ensure proper surface contact to aid in heat dissipation
• Avoid using without heat dissipation if not designed for it
• Check insulation condition, wiring, and terminal positions before use
• Install temperature control systems and overheat protection devices according to risk level
• Avoid using the heater in wet areas or with chemical contact unless certified appropriate
• Cut off power supply and wait for the heater to cool down before removing or maintaining it
