Heat conductive electronic potting silicone

Increased electrical power requires a good quality potting material with good thermal and insulating properties. Silicone rubber is the first choice of electronic potting material because of its good physical and chemical properties and process performance, adding the high thermal conductivity filler, the insulation and heat conductive silicone can be got. As the technology matures, heat conductive electronic potting silicone will play a more and more important role in the protection of equipment, especially in the protection of high pressure high-power components. This article mainly talks about performance requirements and the development direction of heat conductive silicone.   Performance requirements of heat conductive electronic potting silicone: As electronic potting materials, the key indicator of heat conductive silicone is its electrical properties, which is related to the potting silicone whether it can be directly used for electronic potting. Besides, physical and mechanical properties are also important indicators of measuring the quality of the heat conductive electronic potting silicone. Specifically, these indicators need to be noted when you buy the heat conductive silicone, such as, viscosity, coefficient of linear expansion, shrinkage, tensile strength, cementability, thermal conductivity, fire resistance, aging resistance, heat distortion temperature, dielectric strength, dielectric permittivity, volume resistivity, dielectric loss factor, etc.     At present, varieties of heat conductive electronic potting silicone are more at home and abroad. The United States' DowCorning silicone and the first homegrown brand of Hong Ye silicone are well known by the public. Their thermal conductivity can reach more than 0.5 W/（m·K）, For example, the thermal conductivity of heat conductive silicone HY-9055, HY-9045, and HY-9025 is larger than 0.8 W/（m·K）. The operating temperature range of heat conductive silicone is - 50 ~ 250 ℃. And the potting silicone can basically meet the requirements of high-power electronic potting.   The development of transparent heat conductive electronic potting silicone which is convenient to observe the working condition of electronic devices is the development direction of the future. The current product is basically prepared by directly adding thermally conductive filler in the organic silicone rubber, which is difficult to obtain a transparent potting silicone. Hong Ye Company has developed several models of heat conductive silicone with transparent appearance, such as transparent potting silicone HY-9300.   Shenzhen Hong Ye Jie Technology Co., Ltd has achieved a dominant position in the global silicone rubber market. Our electronic potting silicone enjoy high quality and an excellent price performance ratio, which has been exported to more than 90  countries and regions so far and gets its high praise from our customers in quality, delivery time, and services.
