Encapsulating silicone rubber for electronic box

Requirements of encapsulating silicone rubber for electronic box:

As electronic encapsulating materials, the key indicator of it is the electrical properties. Besides, the physical and mechanical properties are also important indicators to measure the quality of the potting silicone. You must pay attention to some performances when you select the heat conductive silicone, namely, viscosity, coefficient of linear expansion, shrinkage, tensile strength, thermal conductivity, fire resistance, aging resistance, dielectric strength, dielectric permittivity, dielectric loss factor, and so on.

At present, there are many brands of silicone for electronic box. Among all the brands, the brand of MC silicone is well known by the people from all over the world, for it has excellent quality and related technology support. Its thermal conductivity can reach more than 0.5 W/（m·K). For example, the thermal conductivity of MC3303, MC3304 is higher than 0.8 W/（m·K）. The operating temperature range of encapsulating silicone is - 50 ~ 250 ℃. And the potting silicone can nearly meet the all the requirements of electronic potting with any high standard.
