With the continuous development of science and technology, PTC heaters have been widely used in home appliances, automotive heaters and other fields. In the production process of PTC heater, silicone gel, as an important material, plays a very crucial role. This paper will introduce the features and applications of silicone specially used for PTC heaters and its advantages in solder joint protection and ultra-high heat resistance.

 Silicone EG0508B is a colloidal material composed of polysiloxane and siloxane. It has strong heat resistance, cold resistance and chemical stability, so it is widely used in electronics, electrical appliances and other fields. PTC heater special silicone gel is a special silicone gel material for PTC heater production, with the following characteristics:

First, the solder joint protection. During the fabrication of PTC heaters, ENIENT silicone can be used to protect the solder joints of the PTC element. The PTC element is the core component of the PTC heater, and the stability of its solder joint directly affects the service life and performance of the heater. The silicone gel has good insulation performance and adhesion, which can effectively fix the solder joint of the PTC element on the base of the heater, and can prevent the solder joint from being eroded by the external environment, thus extending the service life of the PTC heater.

 Secondly, ultra-high heat resistance. The PTC heater will produce high temperature when working, so it is necessary to choose the material with very good heat resistance. The special silicone gel of PTC heater has super high heat resistance, which can work stably for a long time in the temperature range of-60℃ to + 300℃. It can withstand the high temperature of PTC heater without deformation and aging, ensuring the safe and reliable operation of the heater.

 In addition to the above characteristics, the special silicone gel for PTC heater also has good bonding properties and chemical corrosion resistance. It can be firmly bonded to the base of the PTC element and the heater, and will not be corroded by water, acid and base and other chemicals, ensuring the stability and safety of the PTC heater.

 In practical applications, the silicone gel used for PTC heaters has many other advantages. For example, its flexibility is suitable to the production requirements of different shapes and sizes of PTC heaters, and its hardness is moderate to meet the fixed requirements of PTC components without causing damage to PTC components.

 In conclusion, the special silicone gel for PTC heater plays a very important role in the production process of PTC heater. It has excellent solder joint protection ability and super high heat resistance, which can effectively extend the service life of PTC heater and ensure the safe and reliable operation of the heater. Therefore, the selection of high quality PTC heater special silicone material is very important to improve the quality and performance of PTC heaters.
