In the vast world of materials science, vinyl silicone oil is like a bright pearl, shining in many fields with its unique properties and wide application. It is an important member of the silicone family, and vinyl is cleverly introduced into the molecular structure, thus possessing many extraordinary properties.
Vinyl silicone oil usually appears as a colorless or light yellow transparent liquid, non-toxic and odorless, and has no mechanical impurities, giving people a sense of purity. From a physical point of view, its vapor pressure is small, its flash point and ignition point are high, but its freezing point is low, which makes it stable under high temperature and special environment, and it will not easily evaporate, burn or solidify, providing a basic guarantee for its application under complex working conditions.
And its chemical properties are even more eye-catching. The presence of vinyl gives it high reactivity. With the help of catalysts, it can react cleverly with chemical substances containing active hydrogen groups and other active groups to prepare various silicon products with special properties. For example, when preparing high temperature vulcanized silicone rubber (HTV), vinyl silicone oil, as a key base material, works synergistically with crosslinkers, reinforcing agents, etc., greatly improving the strength and hardness of silicone rubber, meeting the stringent requirements of industrial products for material mechanical properties.
Based on the difference in end-capping groups, vinyl silicone oil is mainly divided into vinyl end-capped silicone oil and trimethyl end-capped silicone oil. Among vinyl end-capped silicone oils, vinyl end-capped polydimethylsiloxane (Vi-PDMS) and vinyl end-capped vinylmethylsiloxane-dimethylsiloxane copolymer (Vi-PMVS) are more common. Different types of vinyl silicone oils have their own strengths in applications.
In the production of liquid silicone rubber, vinyl silicone oil is also an indispensable protagonist. It can prepare addition-type liquid silicone rubber with excellent fluidity and elasticity, and has been widely used in scenarios with high requirements for material flexibility and molding performance, such as the manufacture of flexible parts of medical devices and electronic products. At the same time, vinyl silicone oil has also shown its prowess in the field of new material research and development. It reacts with organic materials such as polyurethane and acrylic acid to synthesize new materials that are weather-resistant, aging-resistant, UV-resistant and tough, providing more possibilities for high-end application fields.
In the field of electronics, vinyl silicone oil, as a sealing material, builds a solid protective wall for electronic components and elements, blocking external pollution, moisture and vibration, ensuring the stable operation of electronic equipment and extending its service life. In the release link of industrial production, it is the main raw material of release agent, effectively preventing product adhesion, improving production efficiency and product quality, and playing an important role in processes such as plastic product demolding and rubber product molding.
With the rapid development of science and technology and the continuous progress of industry, the market demand for vinyl silicone oil has shown a growth trend. In the emerging field of new energy vehicles, it is used for battery pack sealants and high-voltage cable insulation materials, meeting the needs of high temperature resistance, aging resistance and high safety; in the fields of 5G communications and high-end electronic equipment manufacturing, its application potential is also being continuously explored. Researchers are also actively exploring the modification technology and new synthesis methods of vinyl silicone oil, committed to improving its performance, reducing costs, further expanding its market application space, and promoting related industries to new heights. Vinyl silicone oil is continuing to shine on the stage of materials science with its unique charm, bringing more convenience and surprises to modern industry and life.
