Relying on the high reactivity of vinyl and the excellent comprehensive properties of organosilicon, vinyl silicone oil has been deeply penetrated into many fields such as addition-type silicone rubber, electronics and electrical engineering, textile printing and dyeing, and high-end coatings. As a core raw material and functional additive, its application scenarios continue to expand, market demand grows steadily, and it promotes the transformation of the organosilicon industry towards refinement and high-end. Driven by the dual factors of downstream industrial upgrading and tightening environmental policies, the application adaptability and industrial development model of vinyl silicone oil are constantly optimized, showing diversified, green and high-end development characteristics.
The addition-type silicone rubber field is the core application scenario of vinyl silicone oil, accounting for more than 60%. As the base compound of addition-type silicone rubber, vinyl silicone oil can be combined with hydrogen-containing silicone oil and platinum catalyst to prepare silicone rubber products with different hardness and properties through crosslinking reaction. In high-end medical silicone rubber, high-purity vinyl silicone oil can prepare non-toxic, tasteless and biocompatible products, which are used in medical devices such as syringes, infusion tubes and medical catheters; in aerospace silicone rubber, its high and low temperature resistance and radiation resistance can meet the needs of extreme environments, and it is used in seals, shock absorbers and other components; in electronic silicone rubber, its excellent electrical insulation can ensure the stable operation of electronic components, and it is used in packaging adhesives, thermal conductive adhesives, etc.
In the electronics and electrical field, the application value of vinyl silicone oil continues to be prominent. In semiconductor packaging, high-purity vinyl silicone oil can be used as a modifier of packaging materials to improve the high and low temperature resistance, insulation and adhesion of packaging materials, avoid packaging detachment caused by high temperature or humidity changes, and ensure the precision and reliability of chips; in electronic adhesives, it can be used as a crosslinking agent to improve the bonding strength, weather resistance and aging resistance of adhesives, adapting to the assembly needs of high-end electronic equipment; in wires and cables, its high and low temperature resistance and insulation performance can improve the service life of cables, which is used for the protection of wires and cables in high temperature, high humidity and strong corrosion environments.
In the fields of textile printing and dyeing and high-end coatings, the application advantages of vinyl silicone oil are increasingly expanding. In textile printing and dyeing, vinyl silicone oil can be used as a softener and finishing agent, which combines with the fiber surface through crosslinking reaction to endow the fabric with soft, smooth and wash-resistant hand feel, and at the same time improve the antistatic property and weather resistance of the fabric, which is widely used in various fabrics such as cotton, polyester and nylon; in high-end coatings, it can be used as a modifier to improve the weather resistance, wear resistance and hydrophobicity of coatings, avoid coating cracking and chalking, and adapt to scenarios such as exterior wall coatings, industrial anti-corrosion coatings and high-end furniture coatings.
The direction of industrial upgrading is clear, mainly presenting three trends: first, high-end upgrading, focusing on the R & D of products with high purity, low volatility and precise functional group distribution, adapting to harsh scenarios such as semiconductors and medical care; second, green development, promoting solvent-free synthesis processes, reducing VOC emissions, and developing degradable and environmentally friendly products, conforming to the dual-carbon goal; third, customized adaptation, developing special vinyl silicone oil according to the needs of downstream segmented scenarios, improving the compatibility between products and downstream systems. In the future, with the continuous development of downstream high-end industries, the market space of vinyl silicone oil will continue to expand, and the industrial value will be further improved.
