Thermal conductive insulating sheet, also known as thermal conductive silicone tape, is the same as thermal conductive silicone sheet, which is both thermal and insulating.

However, unlike thermal conductive silica gel sheet, it can withstand higher breakdown voltage under limited thickness.
Thermal insulation sheet is widely used in many fields, such as MOS power tubes which need thermal insulation.
However, different electrical equipment has different use requirements. When selecting insulating materials, it is necessary to select the appropriate type according to the characteristics of the insulating materials themselves.

How to select thermal insulation sheet correctly? You can focus on the following performance indicators:
01. Compression coefficient
Because many materials increase in thickness after moisture absorption, and the thickness will decrease after drying again, this puts forward higher requirements for the compressibility of thermal insulation materials, such as being able to withstand various deformation and shrinkage conditions.
02. Heat resistance
Thermal insulation materials used in some special occasions have certain requirements for their heat resistance grade. For example, in the application of solar panels, thermal insulation materials have high requirements for heat resistance. If the selected thermal insulation materials do not reach the corresponding level, it is likely to shorten the service life of the entire device.
03. Insulation performance
There are many kinds of thermal insulation materials, and the insulation strength of different materials is different. In use, we need to have a basic parameter guidance for insulation, and then select the corresponding thermal insulation materials according to these parameters.
04. Mechanical properties

In the field of mechanical equipment, vibration, pulling or moving will inevitably occur during use, which increases the difficulty of thermal insulation materials applied to small parts. If the mechanical property of the insulating material is weak, it is easy to be damaged and its insulation property is weakened. Therefore, when selecting thermal insulation materials, measuring their mechanical properties is also a very important link.
