Advantages: silicone potting sealant after curing material is soft, there are solid rubber and silicon gel two forms, can eliminate most of the mechanical stress and play the effect of shock absorption and protection. Stable physical and chemical properties, with good high and low temperature resistance, can work in the range of -50~200℃ for a long time. Excellent weather resistance, can still play a good protective role in the outdoor for more than 20 years, and not easy yellowing. It has excellent electrical performance and insulation ability. After filling and sealing, it can effectively improve the insulation between internal components and lines, and improve the use stability of electronic components. With the repair ability, it can quickly and conveniently remove the sealed components for repair and replacement.
Disadvantages: Slightly poor bonding performance.
Application: Suitable for sealing all kinds of hard working environment and high-end precision/sensitive electronic devices. Such as LED, display, photovoltaic materials, diodes, semiconductor devices, relays, sensors, car ballast HIV, car computer ECU, etc., mainly play the role of insulation, moistureproof, dustproof, shock absorption.
With the development of electronic technology, silicone rubber will undoubtedly become the best encapsulation material for sensitive circuits and electronic devices due to its many excellent properties.
