With the rapid development of electronic technology, the requirements for protective materials for electronic components are getting higher and higher. Vinyl silicone oil has emerged as a key material in the field of electronic encapsulation.
Vinyl silicone oil can be divided into terminal vinyl silicone oil and high - vinyl silicone oil. In its molecular structure, some of the methyl groups on the polydimethylsiloxane main chain are replaced by vinyl groups, which endows it with certain chemical reactivity. This property enables vinyl silicone oil to participate in various chemical reactions, thus playing a unique role in electronic encapsulation.
During the potting process of electronic components, vinyl silicone oil is the well - deserved protector. It can provide a solid protective film for components and assembled parts, effectively isolating moisture, impurities, and chemical substances in the atmosphere, and preventing them from contaminating and corroding electronic devices. Moreover, vinyl silicone oil has a low viscosity and good fluidity, which is convenient for potting operations. It can ensure that every gap of the electronic components is fully filled during the potting process without leaving any dead corners. At the same time, it also has good electrical properties, insulation properties, and mechanical properties, meeting the strict requirements of potting materials for electronic components.
In addition to its application in electronic encapsulation, vinyl silicone oil is also an important raw material for addition - type silicone rubber, organic silicon potting adhesives, and silicone gels. By mixing with cross - linkers, reinforcing agents, etc., high - temperature - resistant vulcanized silicone rubber can be prepared, further expanding its application scope.
